[JBoss-user] [Messaging, JMS JBossMQ] - Re: MDB extends base class: Verification of Enterprise Beans
I barely remember this, so bare with me if I'm not correct, but I do believe that at that time we were trying to isolate the EAR and progress towards J2EE compliance. We avoided this problem by, for the time being, giving up on isolating any EAR that contained MDBs, and consequently, any other EARs they communicated with. Our only isolated EARs today in 4.0.2 are those that don't contain MDBs and don't communicate via RMI to ears containing them, or any other unisolated ear. The suspicion I have, but haven't had the time to prove, yet, is that unless the container itself is configured for J2EE compliance the ears containing MDBs can have this problem. It is possibly related to a classpath issue, because during deploy I noticed that the classpath can be different than at runtime. This isn't the only issue where deployment errors were related to classpath issues that wouldn't have arisen if the EAR was isolated, or because the deployment classpath was different than the runtime classpath. I know this is a vague explanation, and could be proven wrong, but it has explained our behavior and guided our decisions about which ears to isolate until we have the time to convert all our applications into a J2EE compliant state. Ask yourself these questions: 1. Is our container configured for J2EE compliance? I forgot the exact settings, but one is jboss-service.xml/...NamingService/CallByValue. 2. Is your application containing the MDB isolated if your container is not? This setting is in jboss-app.xml for EARs and jboss-web.xml for WARs. In our configuration, we did not get the error when both 1 and 2 were false. In the end, 1 isn't an option for us without code changes due to reliance on a hibernate2 sar, and that change isn't on the project plan yet, so we put off isolating most of our EARs for this release. I suspect that if 1 and 2 are true, you may not get the error either.

[JBoss-user] [Messaging, JMS JBossMQ] - JmsXA not working across distributed JBoss servers
We're using Jboss 4.0.2 and currently support a single instance install of JBoss. We are using XA datasources using DataDirect and SQL Server. We're attempting to support distributing our applications among different instances of JBoss to better manage load. Our tests have all passed in this area except one, JMS XA transactions. We use CMT and JmsXA. Our test goes like this. Remote method on Stateless Session Bean A in JBoss instance 1 is invoked, and it calls Stateless Session Bean B in another ear, which then uses JmsXA to post it to a queue within the same JBoss instance. Stateless Session Bean A then throws a RuntimeException causing a rollback If we run the above test in a single JBoss instance, it works perfectly. The post to the queue is never committed and the MDB never receives the message. If we run the test with Session Bean B in another JBoss instance, with Session Bean A remotely invoking Session Bean B, then it fails to rollback the posting of the message, causing the MDB to erronesouly receive the message. The only difference in the tests is whether or not Session Bean A finds Session Bean B in the same server or in a remote server. Even if it is it is in the same instance, it uses the remote interface and supplies a PROVIDER_URL in the environment during the lookup. It is oblivious and runs the same regardless of where Session Bean B is located Has anyone been able to get this type of configuration to properly rollback? If so, how did you configure it? Will using HA-JNDI/JMS solve the problem? That's a costly step for us as we have a lot of custom configuration and technological dependencies. Right now though we need to get this to work in order to be able to distribute our applications across JBoss instances. We had the same failure to do an XA rollback when we used OIL2 or UIL2 instead of JmsXA in a single JBoss instance. However, in this case, we're using JmsXA and it now works in a single instance. It appears as though the remote session bean invocation is not participating in the XA transaction correctly.

Try using jmx-console (http://localhost:8080/jmx-console). Click service=JNDIView, then Invoke on list(). Look near bottom for Global JNDI Namespace and see if it is there. Perhaps what you really want to use is java:JmsXA which is only in the Java namespace, not global. In this case, you can't have a PROVIDER_URL in your env when you do the lookup because this namespace is only available locally. Just use an InitialContext() without properties.

[JBoss-user] [Messaging, JMS JBossMQ] - Re: How do JBoss Messaging guarantee delivery of messages?
In addition to ensuring that subcribers of topics are durable, the quick answer is to ensure the handler of the message is enrolled in a Tx and rolls back on exception. JMS uses a data source, so you may want to ensure the data source is XA, as we do. The question is what do you do when you have to roll back message handling due to a temporary problem (remote connectivity issue,) and you want to ensure continued message delivery until the external problem is corrected, similar to how SMTP engines usually handle bounces today. I'm working on a proposal for a workaround to issues that I'll post to get peer review here. I'd really love to know how others are solving this problem. If there is an easy solution, I'd sure like to know what it is before we implement a complex workaround.

[JBoss-user] [Messaging, JMS JBossMQ] - Re: Message resent too many times
How about a link to information on how to: 1 Handle unavoidable exceptions in MDBs (highly unavoidable in today's distributed world where MDBs are expected to rely on remote services, such as the database, JNDI and web services.) I'm more than willing to catch these exceptions, if by catching I can ensure requirement #2: 2 Ensure 100% message reliability. 3 Avoid the DLQ. Really, all of our questions are about #2. Reasons on why MDBs should or should not throw exceptions don't anwer question that brings us to this discussion. I found the post I bumped by searching. I read the wiki on every topic and start my search there because it includes both the wiki and the forums. I probably searched for about half an hour before bumping this post. I probably missed something, but I'm not a deity, and am asking for help. I did this search: http://www.jboss.com/search.jsp?query=Adrian+exceptions+in+MDBs and it only listed this thread. If JBoss lacks features to support these requirements, it's better to say so and agree that these are good features for the next version. I don't believe hiding JBoss' shortcomings is productive or in JBoss' best interest. I, for one, have continued to give it my full support despite all the shortcomings I've been fully aware of since 2.4.0. I always said that one of the benefits of open source is open peer review leading to higher quality. This requires open discussion.

[JBoss-user] [Messaging, JMS JBossMQ] - Re: Message resent too many times
We have been using: messageDrivenBeanContext.setRollbackOnly(); which is what the FAQ says to do. The problem is it goes to the DLQ, because if there is a network disconnect in a service the MDB needs, then naturally, the retries run out quickly, as they'll surely fail in the short-term. Ideally, I'd like an infinite retry on network disconnection issues, with a delay, perhaps with a readable retry counter or elapsed time since initial retry so we could determine to escalate it after so long via a per MDB business process solution. anonymous wrote : If you don't want it to infinitely loop on the same error, then you need a DLQ or some other mechanism to avoid JMS trying to redeliver after the rollback/nack. | e.g. redelivery delay in JBossMQ. How can we programmatically throttle the redelivery delay of an individual message? I suspect there's a way, but couldn't figure it out and couldn't find it by searching. The only match I found by searching for redelivery delay was: http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossMessagingConfigurationAndManagementDesign Here is our Destination Manager definition: | mbean code=org.jboss.mq.server.jmx.DestinationManager name=jboss.mq:service=DestinationManager | depends optional-attribute-name=MessageCachejboss.mq:service=MessageCache/depends | depends optional-attribute-name=PersistenceManagerjboss.mq:service=PersistenceManager/depends | depends optional-attribute-name=StateManagerjboss.mq:service=StateManager/depends | /mbean | If we can't throttle on a per message level within the MDB when we rollback the tx, it would be less ideal but still helpful to be able to throttle at the queue or MQ service level. This is not a new issue to us. For a previous service, to avoid the DLQ, if there is an exception, we programmatically stop the queue, and require user intervention to restart it when the problem is resolved. Unfortunately, as we increase our services, this becomes infeasible, particularly when server A is trying to send messages to server B, and server B is trying to send messages to server A. This isn't practical in all situations, and certainly never desirable. Using JBoss search, I couldn't find anything on message or queue throttling. I searched for that too before bumping this thread.

[JBoss-user] [Security JAAS/JBoss] - Re: cant get SecurityAssociation.setServer(); to work
Shameless bump. I have a situation where the client to JBoss is a multi-threaded server to other clients. It uses two basic JNDI authentications, one on behalf of the clients, and one for itself. The problem is that after it obtains a remote interface using its own authentication, when it logs in on behalf of clients (as guest), it gets a security exception when calling methods on the remote interfaces it has for itself. This is because the SecurityAssociation is scoped to the whole application/JVM. Ideally it would preserve its context from the time the remote EJB was instantiated. Short of that, however, I'd at least like to get it to scope to threads, as it's likely that it will never act on behalf of clients in the same thread it's using its own remote interfaces. I tried creating two EJB modules in the same EAR with different security domains, and that didn't do the trick. In this setup the guest authentication was isolated to calls to one EJB module and the host authentication to another. Should I even bother to try to put the EJB modules in separate EARs?

[JBoss-user] [EJB/JBoss] - Cannot access EJB from war inside container
We have an instance where an independently deployed unisolated war cannot access the EJBs in an unisolated ear. They are both in the same JBoss 4.0.2 instance. Applications running in their own JVMs have no problem accessing the EJBs remotely. The problem appears to be related to the use of the UCL, and perhaps Tomcat's classloading behavior. The first exception it throws is a class cast exception when trying to cast the home interface. The second time it tries, it throws 2005-11-01 09:39:31,651 ERROR [com.nwms.emrweb.services.JNDIClientUtil] lookupHome(..)-NamingException: Could not create initial context for environment null | javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interfaces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException: org/jnp/interfaces/NamingContextFactory] | at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:657) | at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:247) | at javax.naming.InitialContext.init(InitialContext.java:223) | at javax.naming.InitialContext.init(InitialContext.java:197) | at com.nwms.emrweb.services.JNDIClientUtil.lookupHome(JNDIClientUtil.java:33) | at com.nwms.emrweb.services.business.ejb.share.ProviderServiceUtil.getHome(ProviderServiceUtil.java:32) | at com.nwms.emrweb.services.business.ejb.share.ProviderServiceUtil.getHome(ProviderServiceUtil.java:37) | at com.nwms.emrweb.services.client.BusinessService.getProviderServiceHome(BusinessService.java:112) | at com.nwms.emrweb.services.client.BusinessService.getProviderService(BusinessService.java:124) | at com.nwms.emrweb.services.client.BusinessService.logout(BusinessService.java:333) | at com.nwms.emr.context.CPRContext.deactivateUser(CPRContext.java:316) | at com.nwms.emr.context.CPRContext.destroy(CPRContext.java:550) | at com.nwms.emr.context.CPRContext.finalize(CPRContext.java:582) | at java.lang.ref.Finalizer.invokeFinalizeMethod(Native Method) | at java.lang.ref.Finalizer.runFinalizer(Finalizer.java:83) | at java.lang.ref.Finalizer.access$100(Finalizer.java:14) | at java.lang.ref.Finalizer$FinalizerThread.run(Finalizer.java:160) | Caused by: java.lang.ClassNotFoundException: org/jnp/interfaces/NamingContextFactory | at java.lang.Class.forName0(Native Method) | at java.lang.Class.forName(Class.java:242) | at com.sun.naming.internal.VersionHelper12.loadClass(VersionHelper12.java:42) | at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:654) | ... 16 more I've never had to add jnp-client within a client app deployed in JBoss before, but for kicks, when I try it, it throws a socket timeout exception.

There are only two instances of the remote home interface being deployed, one in the ear and another in a client jar in the war. The classes are exactly the same. It's compiled once and packaged into the EJB jar and the client jar. Opening the archives in WinRAR reveals that they have the same CRC and timestamp. Using name=Default,service=LoaderRepository from jmx-console reveals that the UCL is loading the class from the ear. It does not list the instance from the war, and I suspect this is because it is being loaded by Tomcat. This is a very critical bug. Please help if you can. I've spent two days on it so far and have run out of configuration permutations to try, including with and without the JBAS-1875 patch, with and without JAAS, etc,...

[JBoss-user] [EJB/JBoss] - Re: Problem with JBoss 4.0.3
I get the just of what it's doing, but I don't understand why I can't call-by-value. I have only been able to successfully get call-by-value to work inside the same JBoss instance when one isolated app calls another isolated app. I have yet to be able to get an unisolated app to be able to make a call by value to another unisolated app in the same JVM, or for an unisolated app to call an isolated app. Because of the latter use case, I have a lot of unisolated apps because they need to call apps that need to call apps that ultimately can't be isolated either because they are using a hiberante 2 sar or because they contain an MDB which seems to have a bug preventing isolation. In the most recent case, I'm trying to resolve a class cast exception on the home interface (see http://www.jboss.com/index.html?module=bbop=viewtopict=71799). So, I set attribute name=CallByValuetrue/attribute for the NamingService in jboss-service.xml. That causes the invalid invocation exception. If i'm asking it to use call by value for all naming lookups, then why is it throwing an exception caused by an attempt to pass by reference between two class loaders? I read somewhere that even if you provide a URL, JBoss detects that it is an intra-JBoss instance call, and converts it to a call by reference. Is there a way to disable this behavior? It would be nice to be able to control when it passes by reference and when it passes by value, and the URL is the most convenient way I can think of to do this. If you don't provide a URL, then clearly you want to pass by reference, or at least invoke locally.

[JBoss-user] [Security JAAS/JBoss] - Re: Simple users/roles login to EJBs not passing username/pa
Thanks a million. That pushed me closer. I created a jaas.conf containing:
JaasJNDI {
| com.sun.security.auth.module.JndiLoginModule required;
| };
and confirmed in debug mode that it loads the configuration.
It gets past the point where it threw an exception trying to extablish a
context in org.jboss.security.jndi.LoginInitialContextFactory.java because it
couldn't find a configuration,
LoginContext lc = new LoginContext(protocol, handler);
and now fails on the next line where it tries to login:
lc.login();
with this exception:
javax.security.auth.login.LoginException: Error: Unable to locate JNDI user
provider
Although I have trace enabled in JBoss for org.jboss.security, nothing is
output when this happens, so I'm not sure if it actually tries to talk to the
server at this point.
The JNDI URL for the home interface is correct, as it succeeds to invoke the
session beans that don't require authorized users of roles when the JNDI
SECURITY_ parameters are not supplied or do not prevent creation of the home
interface.

WOW! I got it. Thanks to the post of tineq I noted that he was using p.put(Context.INITIAL_CONTEXT_FACTORY, org.jboss.security.jndi.JndiLoginInitialContextFactory); whereas I was using org.jboss.security.jndi.LoginInitialContextFactory per the recommendation of http://wiki.jboss.org/wiki/Wiki.jsp?page=LoginInitialContextFactory What do you know, I just plugged and found a http://wiki.jboss.org/wiki/Wiki.jsp?page=JndiLoginInitialContextFactory page! With this class, you don't need to use Context.SECURITY_PROTOCOL or setup jaas.conf on the client. It's as easy as it looks. Both classes are in the 4.0.2 source. I'm not sure at this poitn whe you'd use the class without the Jndi prefix, but it's looking more like a base class rather than a class you'd want to use directly. Perhaps it's needed for some things like LDAP. Anyway, thanks for your help tim.cockle; and your inadvertant help tineq! Hopefully someone else can benefit from the this thread.

[JBoss-user] [Security JAAS/JBoss] - Re: relationship between JAAS, JGSS, Kerberos and JBoss
I can't say I have anything resembling an answer, but I'd have to theoretically ask the question: Can you populate Context.SECURITY_CREDENTIALS in your environment properties when you invoke the EJB? You could have a different login module in your EJBs designed to accept Kerberos credentials. The question is primarily then how you can obtain the credentials necessary to populate Context.SECURITY_CREDENTIALS in your web context when you obtain the home interface to your EJB.

[JBoss-user] [Beginners Corner] - Re: Remote call between isolated EARs
We're having the same problem in 4.0.2. We need to use remote invocation between ears because the ears may or may not be deployed in the same JBoss instance at a customer site. I don't want to use external references in the ejb-jar.xml, because we read our configuration in and prefer to dynamically construct the JNDI lookup at runtime. The code is the same as that used by one of our standalone Java apps that connects successfully, as well as another ear-to-ear case that works. The difference here is that the client is an MDB. The Ear it's invoking containing a stateless session bean is isolated. If the MDB's ear is not isolated, it produces the Invalid invocation. If the ear with the MDB is isolated, it produces: | 18:14:22,897 WARN [verifier] EJB spec violation: | Bean : SubscriberBatchBean | Section: 15.7.4 | Warning: The message driven bean must declare one onMessage() method. | | 18:14:22,897 ERROR [MainDeployer] could not create deployment: file:/C:/Programs/JBoss/jboss-4.0.2_n | ewtest/server/default/tmp/deploy/tmp209594Subscriber.ear-contents/ejb-rdbms.jar | org.jboss.deployment.DeploymentException: Verification of Enterprise Beans failed, see above for err | or messages. | at org.jboss.ejb.EJBDeployer.create(EJBDeployer.java:553) | at org.jboss.deployment.MainDeployer.create(MainDeployer.java:918) | at org.jboss.deployment.MainDeployer.create(MainDeployer.java:910) | at org.jboss.deployment.MainDeployer.deploy(MainDeployer.java:774) | at org.jboss.deployment.MainDeployer.deploy(MainDeployer.java:738) | at sun.reflect.GeneratedMethodAccessor47.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:141) | at org.jboss.mx.server.Invocation.dispatch(Invocation.java:80) | at org.jboss.mx.interceptor.AbstractInterceptor.invoke(AbstractInterceptor.java:121) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:74) | at org.jboss.mx.interceptor.ModelMBeanOperationInterceptor.invoke(ModelMBeanOperationInterce | ptor.java:127) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:74) | at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:249) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:644) | at org.jboss.mx.util.MBeanProxyExt.invoke(MBeanProxyExt.java:177) | at $Proxy8.deploy(Unknown Source) | at org.jboss.deployment.scanner.URLDeploymentScanner.deploy(URLDeploymentScanner.java:325) | at org.jboss.deployment.scanner.URLDeploymentScanner.scan(URLDeploymentScanner.java:501) | at org.jboss.deployment.scanner.AbstractDeploymentScanner$ScannerThread.doScan(AbstractDeplo | ymentScanner.java:204) | at org.jboss.deployment.scanner.AbstractDeploymentScanner.startService(AbstractDeploymentSca | nner.java:277) | at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:272) | at org.jboss.system.ServiceMBeanSupport.jbossInternalLifecycle(ServiceMBeanSupport.java:222) | ... | It's worth noting that we're using the prefix deployment sorter, which is not the default.

[JBoss-user] [Installation, Configuration Deployment] - EJB jar and War classpath issues with deployment verificatio
We're upgrading from JBoss 3.2.3 to JBoss 4.0.2. We have lots of ears with wars and ejb jars, as well as some standalone wars, and a hibernate.sar. We'd like to enable isolation. However, we've discovered a lot of classpath issues that were hidden by 3.2.3's non-compliance. It's often clear when one module is reaching into another module or ear when you remove the one it is undesirably obtaining the class from. What's baffling though is that once you do this the verifier doesn't always appear to be able to resolve classes in its module's own path! In one case, we have a war that is finding a class in another ear. If you remove the ear from the deploy folder and restart JBoss, the war fails to deploy because it can't find the class, although the class is clearly in a jar in its WEB-INF/lib folder! In another case an ear can't find a class in the ear's lib folder, even though it's correctly declared in the ejb module's manifest.mf. In both of these cases, they find the class in another module, ear or sar if you deploy them first.

[JBoss-user] [Messaging, JMS JBossMQ] - Re: MDB extends base class: Verification of Enterprise Beans
I'm getting this in 4.0.2, only I can't find a workaround. In my case, two
conrete MDBs subclass an abstract one that contains the onMessage(), declared
public void onMessage(javax.jms.Message message)
To try to get around the validation error, I subclassed and had the conrete
classes call super:
public void onMessage(Message message) {
| super.onMessage(message);
| }
I'm really confused why this doesn't work. I can understand a bug that can't
find the method signature via the parent class; but not one that's clearly
defined in the concrete classes as well.
Is there a fix? Is there a way I can work around this until we can upgrade?
We just spent a month upgrading to 4.0.2 from 3.2.7, so 4.0.3 probably won't be
an option this year.

[JBoss-user] [JBossWS] - EJB Exception handling
Does anyone know the rules of how to throw and catch exception using stateless session bean web services that also have a remote and local interface? I've noticed that it deploys without error if you throw Exception or RemoteException, although you can't throw the latter from your bean if you have a local interface. It won't allow you to throw EJBException, which certainly does confuse how you implement CMT. In our case, we're converting current code that runs in production in JBoss 3.2.3 to JBoss 4.0.2. The current code throws custom application exceptions that extend Exception, but wscompile chokes on these.

This is a bit offtopic, jdacev, but how does XDoclet handle cases where your beans are subclassed from classes in a reusable library? Particularly, what about when the methods aren't even overriden? This means your project's classes don't actually have the methods, and thus don't have the comments for XDoclet tags.

Your CMP field used a lower case 'd': | cmp-field | field-nameproductId/field-name | /cmp-field | And your primary key class used an upper case 'D': | public String productID; | Also, I can't remember if it is a requirement as I replaced all my composite primary keys with sequence numbers awhile back when there was a problem with foreign keys in primary keys, but it couldn't hurt to add get/set access methods to your primary key class. Sun's tutorial isn't very clear on what a field is in this regard, as they later say that the CMP bean implements the field with its access methods, but includes the instance variable in parenthesis: | In the PurchaseOrderBean class, the following access methods define the persistent fields (vendorId and productModel) that make up the primary key: | | public abstract String getVendorId(); | public abstract void setVendorId(String id); | | public abstract String getProductModel(); | public abstract void setProductModel(String name); | (http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/CMP8.html#72960) Of course, in their PK example, both the instance variable and the access methods are public. The ejb-jar 2.0 DTD is equally vauge, just saying that the fields of the primary key class must be public needs to be public. After you get it working with access methods, just for kicks, try making the instance variable private and see if that breaks it, then post back. I don't have any code I can try it with, because, like I said, I got rid of all my composite primary keys when I upgraded to JBoss 3.0 and implemented CMR. It's not exactly related, but Struts actually reads a form bean's access methods, allowing you to use private or calculated instance data. You'd think J2EE would do the same, but who knows.

It appears as though it creates the index the first time, but can't detect that it already exists the next time, since it's trying to create it again. I would try another database, such as MySQL, to try to determine if it's a JDBC problem. If it works in MySQL or another database, then it is most likely a JDBC problem with HSQLDB. If it iturns out to be a problem in other databases, and thus unlikely to be a specific JDBC problem, can you show the entire trace instead of just the first 3 lines?

[JBoss-user] [Persistence CMP/JBoss] - Re: MySQL 4/JBoss 3.2.3 and CMP 2.0
Whenever your exception is being caused by a database error, the best bet is to see the exact SQL JBoss is sending to the database. There are two options for this. One is to enable logging in MySQL. In your my.cnf, you can add the line: log=/var/log/general.log This can get huge, and is not recommended in production, but is suitable for development. You can always comment it out and restart MySQL when it's no longer needed. Another tip to view recent transactions when the log is large is to stop MySQL, rename (mv) general.log, then restart MySQL, so you start from a new log. The other method is to enable logging of CMP in server/default/conf/log4j.xml, which should show the SQL being generated: !-- View CMP queries -- |category name=org.jboss.ejb.plugins.cmp | priority value=DEBUG/ |/category | When you see the potentially offending SQL, you can often copy and paste it into a command line MySQL client to determine the exact problem, if it isn't already clear.

You can turn on CMP logging to see what it is sending to the database by adding this to your server/default/conf/log4j.xml: |!-- View CMP queries -- |category name=org.jboss.ejb.plugins.cmp | priority value=DEBUG/ |/category | As for how to implement sequence numbers in Oracle, I'm not sure how to set it up to get CMP to automatically do it. Here's a variation of the method I use that uses Oracle sequence objects: - Create sequence controller session bean. - Implement getNextVal and other sequence related methods. - Have it, based on the parameter you pass, do a JDBC call to select the next value from a sequence object. - Have your onCreate CMP methods call the sequence controller and set the primary key value. - Develop the sequence controller to use caching for optimal performance. Create or alter your sequence objects to jump a specified interval. We had ours increment the sequence object by 100. This had the effect of caching 100 sequence values. Thus, the sequence controller would still return an increment of 1 to your CMP bean, but would only call the database to obtain the nextval from the sequence object every 100th time. This increased performance dramatically, particularly during large quantities of inserts, which was typical of our system.

hbaxmann: Thank you for posting the message with kinder English and approaching it technically without commenting on a person's skill levels. I apologize if I was harsh on your choice of words, or use of English. I'll respond to the technical notions in your post now as best I can. anonymous wrote : EJBQL: SELECT DISTINCT OBJECT(t) FROM TheTable t WHERE t.Zip IS NULL OR t.Zip =?1 | | The ?table.col = ?1 OR (table.col IS NULL AND null=?1)? does not work, because there will occur a short-circuit to ?table.col = ?1?, because of ?NULL=anything? is always false. | The problem with that EBJ-QL query isn't that ?NULL=anything? is always false, but that it will return all nulls (t.Zip IS NULL OR ...) even when ?1 isn't null. What would be ideal is: | EJBQL: SELECT DISTINCT OBJECT(t) FROM TheTable t |WHERE (t.Zip IS NULL AND ?1 IS NULL) OR t.Zip =?1 | but ?1 IS NULL is not an option in EJB-QL today. The problem currently with EJB-QL is that you cannot test if the parameter itself is null. The original question I had is when will it or an equivilant be an option, since testing for null parameters has never been an issue with SQL development before? Although EJB-QL chose to adhere largely to SQL syntax, I think that to solve the problem where it is clearly deficient in contrast to SQL, and particularly dynamic SQL where you combine code logic with resulting SQL output, it could improve by doing things differently. In Java, variable=null does return true if the variable is null. Why not permit it in EJB-QL? The requirements for this entity are: - Reusable by all applications - Works with all database vendors - Works with all J2EE vendors - Very high performance - Extremely simple Views are ruled out for two reasons. One, they are an unacceptable hit on performance. Two, they are not supported by all database vendors. Now, let's say that views were acceptable. Using your example, 16 views would be necessary in this case. The reality is there are 4 optional columns in the business key. Any of them can be null. The keys are not related to each other. Any conceptual relationships that might occur inthe applications is arbitrary. Using the samle you posted, meaning that views didn't have unions, you would have to have 16 individual views just for this one query to handle every possible combination of null / not-null values. Contrast this to my current solution of using dummy null values. It's working today. It doesn't have the high performance cost of views, and works with all database vendors. It is seemless to the applications, since they can still use nulls, and will still get back nulls, never knowing that a dummy null value was substituted. Thus, this entity became one of a growing list of examples since EJB-QL came out of problems with nulls in the queries. But, using views clearly are not in line with the requirements. The question I originally asked is what was the progress of JBoss or J2EE on this issue? The question was partially answered when someone said you could do it today with DynamicSQL. That last time I check, DynamicSQL couldn't do it, ironbird essentially answered my question as to where JBoss has progressed on it today. The only question I still have is where is J2EE and the JSR's on this? Thank you hbaxmann for helping. Your proposal to use views to denormalize certain can work and has merit. It's just not the option for the problem I have. And thank you ironbird for the DynamicSQL info. Although this entity needs to work with all J2EE vendors since it's in a foundation class library, I'll probably use DynamicSQL until a JSR fixees this for entities that can afford some vendor dependency. Happy JBoss development!

[JBoss-user] [Persistence CMP/JBoss] - Re: Nulls in CMR where clause
hbaxmann: You are clearly learning relational theory in an academic setting. What school are you attending? What is your major? For one, no one completely normalizes data in the real world, and by real world, I mean business applications. When someone does, it's clear it's a college student or grad that hasn't had the experience beyond what he learned in school. Null columns exist because the user is not always required to provide them. Like you said, it gives us the ability to detect that there is no data for it. It's a very nice concept and works really well in relational databases. There's no normalization problem because you have optional columns. If I wasn't using EJB-QL, but DynamicSQL, as someone suggested, or direct JDBC, I wouldn't have a problem at all. Using the example of customer registration, here are columns I might make optional because I wanted customers to register even if they didn't have or want to provide the information: - All address information. Definately second address line if I chose to require address information. - Second email address. - Additional phone numbers. Now, all this info could be normalized, but with an OO front-end, the benefits are near nill. Take the phone number, for instance. Phone numbers can be handled in a standard way via application objects. This mutes the benefits of normalization. However, even if I normalized it, I would still have optional foreign keys... and thus nulls. This would not resolve the problem EJB-QL has, as it applies to relationships as well as regular columns. Optional is optional, whether they are regular columns or relationships. Optionality is defined by the business requirements. If the phone number is not required information, then either a column for phone number data or a foreign key can be null. As for ER modeling, I've been developing relational applications since the early 80s prior to SQL's definition in 89. I've read quite a few books over those years, including the adademic books you're reading now, as I have a degree in IS. I've used ERwin, Oracle Designer, Rational Rose and other tools for ER modeling. Last year, I lead the effort to create a 150+ table data model for a large commercial payroll company for DB2. We used Rational Rose to create an ER model. When that was complete, we generated the data model, and then revamped it some more. Then we generated it in DB2 migrated an entire commercial payroll system to use it. It was successful. We did a lot of normalization of the data coming in, which came from the mainframe in over 100 formats. Creating a practical normalized model was one of our goals. But knowing when to normalize and when not to normalize isn't something you can learn in an academic book on relational theory. It's something you learn by repeatedly doing it in the real world for many years. Building data models for large businesses over and over again is the real world. Learning relational theory in a class is not. Using views to try to normalize a single table is rediculous in this case, both in terms of practability and the end result's ability to actually solve the EJB-QL issue. Even if it did somehow miraculously help, it would run completely counter to why I'm using CMP, and the database vendor independence required by the application. Please read comments I made earlier on why I am using CMP. It's exciting to see you learn relational theory. Clearly, you are grasping the concepts your class is teaching you. However, I highly recommend you try to learn from others who have applied it in business environments, and give them the benefit of the doubt until you have a chance to learn the practicality of some of the academic ideas when developing large business applications.

I am normally very supportive of people learning something new. His tone was condescending, so I felt he needed to hear himself in context. There's a difference between someone that is new, and someone that just learned something in a class and think they know it all and can log onto a forum to insult everyone that think exactly like he thinks. I figured a gentle correction on a JBoss forum was a better place for him to learn than on a job. Unfortunately, I didn't know how to do that without coming off as condescending. I would have probably dismissed what he said outright, if it wasn't for his display of lack of ettiquette: - your ER model sucks - because in this kind of usage your Entity design simply lacks - dont blame the J2EE for not resolving bad RDBMS design This is in addition to outright illogical statements he made, his assumption that he's completely right without even understanding the problem, his inability to listen to why I chose certain options, like avoiding dynamic SQL or direct JDBC, and the lack of inquiry into the actual table design and purpose. By the way, the table which he thinks needs to be normalized with views only consists of a primary key (generated sequence number), a composite business key, and a single column for data. It's ok if his logic is incomplete, but he should try not to condescendingly insult people when he displays his lack of understanding of other people's problems.

[JBoss-user] [Persistence CMP/JBoss] - Re: Nulls in CMR where clause
The problem with that query is that it will return rows where c.customer IS NULL but the parameter ?1 is not null. You only want rows where c.customer is null and ?1 is also null. The equals doesn't work, and IS NULL only tests one side of the equation. You can't apply it to the parameter to be sure both the parameter and c.customer are null at the same time. I've worked around this by creating multiple queries to test for the various scenarios, and then aggregating the results. That's extremely inefficient, but the runtime inefficiency is not the biggest problem. The problem is that the number of queries you need is the number of optional parameters you have to the power of 2. For instance, if you have two optional parameters, then you need 4 queries to cover all possible combinantions of null and not null values. However, I'm asking this question today because I now had a case where the business key has 4 optional columns. This would require 16 queries, and I'm not going there. To get around this for now, I created a dummy null value, and have a lot at points to convert it back and forth between a real null. This was at least better than creating 16 EJB-QL queries and creating a lot of Java code to tie them together.

How is having multiple optional columns a bad model? anonymous wrote : And your query, even implemented in SQL, is 100% compatible with all the databases because SQL address the database compatibility before java and J2EE. Wouldn't that be nice if it were true. To name a few differences: the formatting of a date in the where clause, unique identifier generators and the syntax of outter joins. I wrote one system that ran in both SQL Server and Oracle. Last year, I lead the migration of a J2EE application to use a new DB2 data model with 150+ tables while still working 100% with its Oracle 90+ table predecessor. To complicate things, we had to use stored procedures for all data communication for DB2 (dumb security standard .) The calculation code, which never stopped being fully functional during the entire migration, was 100% independent of the database vendor, but it it wasn't SQL that made it possible. We used a Data Accessor pattern. There are two two problems with SQL: The ANSI 89 and 92 standards that became popular did not address all the needs (e.g., dates in the WHERE clause). The second problem is that it is relational, making it difficult to migrate to object database technologies. Thus... CMP, and the current trend of using object-relational to implement it. If Sun's Java certification has anything that requires CMP to use a relational database, then they are not testing the standard, because nothing in the standard requires a relational database for implementation. If they relational database requirements have drifted into it, then it's probably just because every vendor out there implemented it with a relational model. Thus, when vendors start to implement it with object databases as well, Sun will be obligated to remove any relational specific requirements that slipped into their test suite.

[JBoss-user] [Persistence CMP/JBoss] - Re: Nulls in CMR where clause
hbaxmann: anonymous wrote : solution: build a db view per optional field, null-'key' rows will vanish, not the denormalized table This isn't a relational issue. The query I mentioned with 4 columns ironically has no relationships whatsoever. However, it does have 4 optional columns I need to filter on. They happen to be parts of a business key, but that's arbitrary. They could be any optional column that I need to filter on. Remember, this issue is I'm passing a parameter and pulling values that match that paramter. This isn't complext, and has nothing to do with normalization because it has nothing to do with joins or relationships. anonymous wrote : if your app rely on more then one _significant_ optional field - your ER model sucks Huh?!? More than half a table's columns are often optional. Any column can be filtered via a parameterized where clause in the real world. These are common business requirements. Just because a customer table does require an email address doesn't mean the user shouldn't be able to query based on the email address. Just because an email address is optional doesn't mean that every other piece of customer information has to be mandatory. How is having multiple optional columns a bad model? hbaxmann: I think you understand where I'm coming from. J2EE has some great enterprise quality standards. But other standards, such as JAAS, don't fit the bill for enterprise readiness, IMHO. While I know CMP has is a bit short on some critical areas, such as its support for optional columns in a query where the parameter can be null, I'm investing in CMP for the long run vision. Thus, I'm taking the time to try to find the best-of-breed solutions that others are using to deal with the bump along the way; and, in the absense of such, trying to sense the priorities of others and how it's driving the improvement of the standard. In other words, I need to understand the priorities the CMP developers are sensing so I can bet on likely improvements. anonymous wrote : And your query, even implemented in SQL, is 100% compatible with all the databases because SQL address the database compatibility before java and J2EE. Wouldn't that be nice if it were true. To name a few differences: the formatting of a date in the where clause, unique identifier generators and the syntax of outter joins. I wrote one system that ran in both SQL Server and Oracle. Last year, I lead the migration of a J2EE application to use a new DB2 data model with 150+ tables while still working 100% with its Oracle 90+ table predecessor. To complicate things, we had to use stored procedures for all data communication for DB2 (dumb corporate security standard.) The calculation code (business logic,) which never stopped being fully functional during the migration, was 100% independent of the database vendor, but it wasn't SQL that made it possible. We used a Data Accessor pattern. There are two problems with SQL: The ANSI 89 and 92 standards that became popular did not address all the needs (e.g., dates in the WHERE clause). The second problem is that it is relational, making it difficult to migrate to object database technologies. Thus... CMP, and the current trend of using object-relational to implement it. CMP offers a migration path if you believe it will one day support object database implementation. If Sun's Java certification has anything that requires CMP to use a relational database, then they are not testing the standard, because nothing in the standard requires a relational database for implementation. If the relational database requirements have drifted into it, then it's probably just because every vendor out there implemented it with a relational model. Thus, when vendors start to implement it with object databases, Sun will be obligated to remove any relational specific requirements that slipped into their test suite. However, this is all conjecture. Do we even know that Sun's test suite has relational database requirements unwittingly embedded into it? It's Sun's own website that states that CMP does not need to be implemented using a relational database. Here's one instance: anonymous wrote : It is unlikely that the EJB expert group will accept any form of Java transparent persistence as an EJB requirement; however, some J2EE vendors may well use JDO as the underlying implementation of CMP. - http://java.sun.com/products/jdo/JDOCMPFAQ.html View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=3836353#3836353 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3836353 --- This SF.Net email is sponsored by: Oracle 10g Get certified on the hottest thing ever to hit the market...

[JBoss-user] [Persistence CMP/JBoss] - Re: Configuring JBoss CMP for a caching enviroment
JBoss caching is very configurable. I CMP configuration samples on this computer, but I'm sure others can show you examples of how to configure CMP's caching. Virtually all database caching uses lazy loading, since you can't anticipate what the user will need to read ahead of time, and don't want to load the whole database in memory by default. Principally, you can primarily tweak the timings and pool sizes. With the former, you're anticipating usage patterns. With the latter, you're weighing memory usage efficiency usage versus performance. JBoss comes out-of-the-box with default configuration for your CMP beans. To override, you create your own configurations (can copy JBoss default, and then rename and modify.) You can then apply your configuration to beans on an individual basis. You both define configurations and then associate them with individual beans in your jboss.xml.

[JBoss-user] [Security JAAS/JBoss] - Re: Security context propagation from web client to ejb
This is why I chose tokenized security instead of JAAS, which I view as a work in progress. You can pass a user session token as a simple parameter to any EJB method from any Java client. With one line of code, your EJB method can validate that the user has access to the business method. The line of code will throw an AccessDenied exception if the user does not have access, which your client framework can handle in a standardized way. No container context is required for tokenized security. Indeed, it is even J2EE vendor independent, so your WebSphere clients can call JBoss EJBs.

I've never had a problem running JBoss 3.2.3 on RH 9. I'd recommend downloading it again, and checking that the server/default/deploy/snmp-adaptor.sar/META-INF/jboss-service.xml is there when you unarchive it. One thing worth mentioning, though, is that when you run as root, certain files that JBoss writes to will become owned by root. This creates a problem when you then try to run it as a non-root user. You need to do a chown or chgrp -R to reenable another user to run it anytime you run it as root.

I did put another post though where I ran into a snag tighening down JBoss by running it under a 'jbossuser' with very limitted rights. Primarily, even though I SU'd to 'jbossuser' to run JBoss, it still tried to put the temporary files in the home folder of the original user I logged in as when it compiled JSPs. I can't log in initially as 'jbossuser' because I need the ability to SU as root and don't want to give this ability to 'jbossuser'. Do you know how to solved the temporary file problem? Is there a way I can tell it where to create temporary files during JSP compilation? This is using JBoss 3.2.3, integrated Tomcat and Jasper.

[JBoss-user] [Security JAAS/JBoss] - Re: SSL configuration
There are two ways you can do this. One is through Apache HTTPD, and another is directly in Tomcat. I use the former. To use Apache as your HTTPD, you use Tomcat's JK to forward requests from Apache to Tomcat. http://johnturner.com/howto/apache-tomcat-howto.html Then you setup Apache to use SSL: http://httpd.apache.org/docs-2.0/ssl/ I found the FAQ to be the most useful, giving step-by-step instructions for creating and deploying a certificate. I had to Google search to create the sign.sh. Then you simply define a virtual host that both enables SSL and defines your JK forwarding request. Here is an example: | VirtualHost 192.168.1.56:443 |ServerName secure-webserver.com |ServerAlias *.webserver.com |DocumentRoot /usr/local/www/data | |ErrorLog /var/log/httpd-secure-error.log |TransferLog /var/log/httpd-secure-access.log | |SSLEngine on |SSLCipherSuite | ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL |SSLCertificateFile /usr/local/etc/apache/ssl.crt/sitessl.crt |SSLCertificateKeyFile /usr/local/etc/apache/ssl.key/sitessl.key | | osnet:/ | | ## Static files | #Alias /moredocs /usr/local/www/moredocs | |Directory /usr/local/www/osnet |Options Indexes FollowSymLinks |DirectoryIndex index.jsp index.html index.htm |/Directory | | # Forwards ALL requests to Tomcat |JkMount /* ajp13 | | # Optional limitted forwarding examples: | # JkMount /*.jsp ajp13 | # JkMount /servlet/* ajp13 | /VirtualHost | Keep in mind that named virtual hosting doesn't work with SSL as it can't read the header in the HTML. Thus, the ServerAlias is kinda useless. You can, however, use IP or port based virtual hosting, which, of course, can be mapped to subdomains. Otherwise, when using SSL, it will grab the first virtual hosting entry you have for a given IP/port.

I wish that were true, because all users have write access to the folder it points to: '/var/tmp'. Unfortunately, it's trying to write then read a file in the home folder of the user I initially log into before I SU to 'jbossuser'. Thus, if I originally log in to user 'sam', then I get java.io errors while compiling JSP errors saying it can't find file '/home/sam/fileBlahBlahBlah'. Since user B doesn't have access to user A's home folder, this can never work unless I find a way to override its current behavior.

[JBoss-user] [Installation Configuration] - Re: SU jbossuser temporary file problem
I'll test this as soon as I can take the server down (production). But, I don't think this is the same thing. Currently, when I don't use SU, it creates a work directory under the jboss tree, and this works fine. The compiled JSP pages go there. E.g., ../jboss-3.2.3/server/default/work/MainEngine//JSP servlet java and class files You can see this for all the hosts I have setup in the file you referred to. When I use SU and a restricted user, it can't get far enouth to produce a servlet for the JSP. The temporary files where it is erroring on are very very temporary files, not the resulting Java and class files for the JSP pages that end up in the work folder. They have cryptic names, as you would expect for temporary files (something like 'fileX827SEJ8293'). They appear to be files Jasper is creating in the compile process. Thus, the error says something like ... java.io.BufferedInputStream... cannot read file /home/sam/fileSKJ2354SJS3 I'm going off the top of my head, but I'll copy and paste when I can take the server down and play with it again.

[JBoss-user] [Security JAAS/JBoss] - Re: Jboss and Apache and PHP?
I can't say it's not possible, as you can now run scripts in Java. You should look at apache's Jakarta projects, as I remember one of them giving the ability to run script languages from a Java web server. I'm not sure if you could extend this to run PHP. Even if you do, how would PHP access the session information? You'd probably end up creating a servlet wrapper for your PHP so it could supply this info. Other than that, though, I'd say typically the answer to your question is no. PHP is configured in Apache. The way you configure JK is you tell Apache to forward requests that match a pattern to Tomcat. I've never heard of Tomcat being able to handle PHP, except possibly through the theoretical method I mentioned in the first paragraph. I've thought a lot about this problem. You can have Apache forward only requests that match *.jsp or /servlet/*, but then what about images and other things that could feasibly be in both Apache and your war? For the time being, I've resorted to putting everything in the war, because I don't want a war to have to depend on external images, html, or any other type of file. There is one work around, though. You could create separate virtual hosts, and have one forward to Tomcat, while another accesses a local repository. You might use a different subdomain. You can setup each virtual host's JK forwarding differently. If I need infrastructure outside J2EE, such as PHP, this is what I do. But, let's say you have php.mydomain.com setup for your php applications, and www.mydomain.com setup for Tomcat. The problem in your case is still session management. Since J2EE handle's user session manangement internally, how can your PHP content running through Apache possibly share the same session information? I do plan to solve this sometime down the road with JoshuaBranch AS (JB-AS), which uses tokenized user access. Eventually, I'll have SSO completely integrated in it, which can be shared across any server using JB-AS. Then, I'll have client interfaces for PHP, among other languages. This will permit J2EE, PHP, Python, Perl, and even .NET to share a user's session across all servers in an enterprise. This is down the road, though. Today, JB-AS has a client interface for any J2EE container (JBoss, WebSphere, etc,...), and can secure both the Web and EJB modules They can all share the same live data, so you can centrally manage your application security for all your J2EE applications on all your servers. However, the current API doesn't offer applications the ability to share a user session (SSO), and the API for non-J2EE clients isn't available, yet.

[JBoss-user] [Security JAAS/JBoss] - Re: J2EE and JBoss virus alerts
I'll check it tomorrow, and post the results. I highly suspect that these are false positives, but not for the same reason as you. I get the impression you're still caught up on the fact that it reported BAT (win32), which is OS dependent. The point I made in the previous post is that Java code could still be used to propogate win32 viruses, even on Linux boxes, because you don't need to execute the virus being propogated to propogate. Propogation can be done entirely with network communications. However, it's also important to know that Java can execute win32 code. For a project I worked on last year, our tax libraries were compiled in DLL and SO formats for Windows and Linux respectively, with a Java wrapper so we could call them in Java. Thus, Java can call OS specific executables. I'm not sure how the Java wrapper worked, but it worked. I can assure you of that. I do remember that the wrapper used reflection. It loaded the correct libarary at runtime based on what we put in a properties file.

[JBoss-user] [Security JAAS/JBoss] - Re: ssl config in Jboss-tomcat
I'm curious, what are the benefits of using SSL in Tomcat instead of Apache? I'm wondering if it overcomes any of Apache's limitations. The primary limitation in Apache is that named virtual hosts doesn't work, although you can still use IP or port virtual hosting. Does named virtual hosting work if you use Tomcat for SSL? Do you have to sacrifice anything to use Tomcat's SSL?

[JBoss-user] [Installation Configuration] - SU jbossuser temporary file problem
For some reason, when I SU to a user for JBoss to run, it still tries to use the home directory of the user I physically logged into before I used SU to write temporary files for JSP compilation. The process goes like this: - Log into OS with user joe - Launch X (gnome) - Run script in terminal that runs JBoss as user jbossuser - JBoss runs successfully, because during initialization, it only accesses the files inside the JBoss folder, which jbossuser is the owner of. - Try to access JSP page. - JBoss gives JSP compile error, which traces down to file.io error, because it cannot find a temporary file it thought it created in /home/joe! jbossuser does not have read/write access to /home/joe, so naturally this is going to throw an exception. When I SU as jbossuer, ~ and $HOME both correctly map to /home/jbossuser. $home maps to /home/joe, so I exported it to /home/jbossuser before launching JBoss. This still didn't fix it. Where is it getting the location for temporary files when it compiles JSP pages? How can we tell it to put the files elsewhere? The only way I could get it to run successfully under the jboss user was to initially log in with that user. This is not acceptable since this user cannot SU as root, and giving it the ability to SU as root defeats the whole purpose of creating an ID that has minimal privileges. The idea is that if the web server is compromised, I want to limit the damage. This, of course, means that I absolutely want to do everything I can to ensure that access via jbossuser cannot be escalated to root. IMPACT: Basically, I prefer to run the OS with X and JBoss in a terminal so I can see all output at any time, live. By logging in initially with a user that has the ability to SU as root, I can fullly administrate the server while JBoss continues to run. Due to this problem my options are only to run JBoss under a user that can SU as root, which goes against the whole purpose of creating and using a user ID that has minimalistic privileges. Or, I can initially log in as the JBoss user, losing the ability to SU as root to administrate the server, something I do often (e.g., to change Apache configuration files.) If I use the latter, then I have to take down JBoss, and thus my web sites, just to update something that has nothing to do with JBoss.

One poster noted that you can obtain a CMP data source via JNDI (1099). A reply noted that you can secure it with a SecurityManager, but I'm not sure I understand how this works with remote connections. Until I fully undestand how to implement container security across a remote connection, I consider 1099 something to be firewalled. Even if you can secure your EJB API (which I already did with tokenized security) and secure the data source with container security, what about the default JBoss features of JNDI? What about undocumented or rarely understood queries? I think we need a comprehensive guide to securing JBoss, particularly JNDI/RMI.

I don't have untrusted entries in the Run keys of the registry. The only other files showing virus alerts are countless emails we all receive and know better than to open (e.g., Skynet via PIF files.) All indication is that barring the J2EE classes above, my machine is not running a virus. I was able to visually verify that the product_update.htm alert was a false positive, unless my eye missed something. I didn't see any scripting in the file. Has anyone automated the process of verifying the integrity of their Java components? Do I have to compile to be sure? Even so, how do you know javac is not compromised? In this case, I'd really like to check the integrity of just the individual classes, but don't really want to go through the hoops of downloading all the source and compiling, and I'm not sure that's possible in all cases or realistic. Even on FreeBSD, where I compiled the JVM, I'm not sure what the best process is for daily checking the integrity of the classes. I dread recompiling the JVM since it takes so long, and will require bringing the server down. Due to Window's lame file security, the possibility of having your Java classes in various libraries become infected is significantly higher on Windows than BSD/Linux/Unix OS's. The Windows box I'm concerned about is used for testing and production backup, though. Until this is resolved, I'm not running J2EE on this computer. Unfortunately, since this is a test box, this puts a damper on my application escalation process, delying production updates View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=3830112#3830112 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3830112 --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.

[JBoss-user] [EJB/JBoss] - Re: comminucate to another application server.
I have found that JNDI works great, so you don't need the complexity of rmi-iiop. Currently, I tested it successfully with JBoss -- JBoss and WebSphere -- JBoss, although I had to include the JBoss client jar for WebSphere. Basically, if your JNDI look internally was MyApplication/MyBean, then your JNDI for remote lookup might be jnp://remotehost:1099/MyApplication/MyBean. You can obtain any remote EJB interface this way so long as you can plug the host name or IP address for the remote server in the lookup string. I have the Web module grab this from a properties file. For EJB to EJB, you might grab the remote host or IP from a user updateable database entry. Let me know if you need more details.

Can you think of another way to write the EJB-QL to accomplish this? After looking at the SQL I think I'd probably consider a subquery or union to avoid the inner join if I were doing this in SQL. Of course, MySQL is adding these features into its newer versions, so I'm not even sure they are options. I'm not too sure how the J2EE spec handles this. My guess is that it doesn't address it. The question is, does JBoss need to use some sort of DISTINCT UNIONs or subquerires (simuluated of driver or database doesn't support) to handle OR operations containing an inner join on one side of the OR? Does it perhaps need a level of abstraction to complete queries in object form instead of converting them entirely to a single SQL statement? I'm not familiar enough with the details of CMP 2.0 requirements to really understand what all is involved. Of the least, I hope JBoss CMP developers are involved in the JCP process.

[JBoss-user] [EJB/JBoss] - BUG: EJB-QL OR operator fails with nulls in inner join
I think I found a bug in EJB-QL. Please correct me if I am doing things incorrectly. I'm very much aware of the limits in EJB-QL today with regards to NULLs, and have had to create many queries to handle instances where parameters would otherwise NULL values. There's nothing more I'd like to see fixed in J2EE than today's limitations to EJB-QL. However, this is different as it does not depend on parameters at all. Instead, it is based solely on the values in the database. Basically, I have a case where a user session (s) includes a domain ID, which may be null. Similarly, each user role is tied to a domain, which may be null. The null values represent a concept I call GLOBAL and are valid. In EJB-QL, I am tryting to say the following: - If the session domain Id is NULL, give me all roles belonging to the user. Otherwise... - only give me user roles that match the sesion's domain Id. This is the logic that fails wiht EJB-QL: s.domainId IS NULL OR s.domainId = rm.role.domain.id In a test case, a user has 3 roles, and one of them is GLOBAL (null domain). For the GLOBAL one, the following assertions are true: s.domainId IS NULL rm.role.domain IS NULL The latter assertion is where I believe JBoss is having trouble handling the OR propertly. If I only include s.domainId IS NULL in the EJB-QL, then I get back all three roles if the domainId is null, which is correct. If I only include s.domainId = rm.role.domain.id in the query, then I only get back the two matching roles if s.domainId is not null. This is correct, since rm.role.domain is null in this case, making it impossible to obtain the id of the domain. However, when you combine them with an OR statement, I suspect that JBoss is incorrectly restricting the results to this inner join even when s.domainId IS NULL . Thus, it is not correctlyapplying the OR statement, which should in effect return a unique union of the two result sets on both sides of the OR. Here's is the complete EJQ-QL that fails to ever return roles with a null domain: | SELECT DISTINCT OBJECT(rm) |FROM rolemodules AS rm, | IN (rm.role.userRoles) ur, | IN (ur.user.sessions) s |WHERE s.id = ?1 AND s.randomId = ?2 AND | (s.domainId IS NULL OR | s.domainId = rm.role.domain.id) AND | rm.module.application.name = ?3 AND | rm.module.name = ?4 | Has this been fixed in 3.2.4? If not, how do we submit bug reports? I've been using JBoss since 2.4.0, and honestly don't know how to submit bug reports.

[JBoss-user] [Frequently Asked Questions (FAQ)] - Re: setting up a virtual host with 3.2.3 (without Apache)
This certainly helped, as it now recognizes the virtual-host setting. However, my problem is that I need it to support multiple virtual host settings. This is to support escalation from development to testing to production, each having a diferent virtual host name. I have alias tags in the host setting of jbossweb-service.xml. If I change the virtual-host setting in jboss-web.xml to any of them, it works only for that host name. This is good in that it indicates that my alias tags are working. However, I need it to work for all the alias tags for that host. If I try to set more than one virtual-host tag, I get the following error: org.jboss.deployment.DeploymentException: Failed to parse WEB-INF/jboss-web.xml; - nested throwable: (org.jboss.deployment.DeploymentException: expected only one virtual-host tag) The bottom line is that JBoss needs to support multiple virtual-host tags, or have a means to support virtual host aliases. Is there a workaround?

[JBoss-user] [Installation Configuration] - Re: JBoss LDAP configuration with Novell eDirectory 8.6
I've created a centralized role-based J2EE security service called JoshuaBranch AS and plan to publish a commercial version (free for non-profits) this month at JoshuaBranch.com (the site will be up within a few weeks). LDAP authentication is planned for one of the upcoming versions. LDAP authentication is a bit complicated, but it will be simplifid for the Security Administrator (SA). The applications using the security service will be oblivious to how the users are authenitcated, so users of the current version wil not need to change a single line of code to utilized LDAP. The SA will define how users are authenticated via a security administration web front-end to the centralized service, and configure LDAP connection parameters, meaning that applications using the current version will not need to change any code to use it, although a redeploy could be required to include up-to-date client jars. Currently, any J2EE application can use the centralized security service, including JBoss and WebSphere, even though it runs in JBoss. In other words, you can administrate security for all of your J2EE applications via a single security administration web console even if the applications are running on disparate J2EE vendor servers and multiple server instances. This is ideal for enterprises migrating over to JBoss, while continuing to use WebSphere or WebLogic. If you would like to be informed on the roll out of JoshuaBranch AS, send an mail to joshuabranch-as-news at joshuabranch.com requesting to be put on the news list. a href=http://www.jboss.org/index.html?module=bbop=viewtopicp=3825531#3825531;View the original post/a a href=http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3825531Reply to the post/a --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.

[JBoss-user] [EJB/JBoss] - WebSphere War to JBoss EJB lookup - how to?
How do you do a JNDI lookup from WebSphere from a War to obtain the home reference of a remote EJB in JBoss? It currently works from JBoss clients without a problem using this PROVIDER_URL for the JNDI lookup: jnp://192.168.1.8:1099 from WebSphere, however, I get this error: javax.naming.ConfigurationException: Bad protocol: jnp Basically, I have a service in JBoss I want to be accessible to all J2EE clients, starting with JBoss and WebSphere. a href=http://www.jboss.org/index.html?module=bbop=viewtopicp=3824804#3824804;View the original post/a a href=http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3824804Reply to the post/a --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.

If there's another way, I'd sure love to understand it, because right now I cannot figure out how to get a WebSphere client to obtain the remote home interface of an EJB in JBoss because it considers the 'jnp' protocol invalid.

[JBoss-user] [EJB/JBoss] - Re: accessing Local Interfaces from JSP's
View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=3821638#3821638 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3821638 I would still recommend using only local interfaces for entity beans and only letting EJBs access them to ensure several things: - They cannot be accessed by remote machines (security). - You'll have the ability to use CMR with CMP beans. - You create proper design where the Web tier is oblivious to data sources and operations. The EJB tier, likewise, should focus on data and business functionality, oblivious to client presentation. This design encourages modularity and reuse, among other things. Keep in mind that remote interfaces are accessable anywhere on the network that is reachable. Local interfaces are not accessible outside the container. I personally never access local interfaces from outside an EJB module to ensure that the remote session interfaces correctly spec the requirements of the web modules, no more, no less, so web modules can be safely distributed in any container while EJB modules truly encapsulate the how of the business process. An example is an EJB module that authenticates users. The client can call it oblivious to how users are authenticated. They do not need to know that LDAP even exists, let alone if it is being used. At the same time, the remote interface methods are limited enough to ensure that it is impossible to obtain a valid session token without proper credentials. I wish that local interfaces weren't accessible outside the EJB module because it is unnecesarily challenging to secure an EJB module from rogue or compromised processes in the same container. If classes can have private and protected members, then why can't local interfaces have some sort of intrinsic protection? --- SF.Net is sponsored by: Speed Start Your Linux Apps Now.

This blows me away because when I set JBoss' host to be 192.168.1.8 via --host= I get
connection refused from 127.0.0.1. But, when i set JBoss' host to 127.0.0.1, I get
connection refused from 192.168.1.8!
Here is the code I'm using to try to connect:
Context context = getContext();
log.debug(Context.DNS_URL: + context.DNS_URL);
log.debug(Context.INITIAL_CONTEXT_FACTORY: +
context.INITIAL_CONTEXT_FACTORY);
log.debug( Context.PROVIDER_URL: +
context.PROVIDER_URL);
Hashtable table = context.getEnvironment();
String url = (String) table.get(context.PROVIDER_URL);
log.debug(URL: + url);
ClientConfig config = new ClientConfig();
config.setRemoteJNDIhost(192.168.1.8);
url = config.getRemoteJNDIurl();
log.debug(new URL: + url);
try {
table.put(Context.PROVIDER_URL, url);
context = new InitialContext(table);
Object remoteObject =
context.lookup(url + / + SECURITY_CONTEXT_NAME +
/SecurityController);
log.debug(Obtained remote home interface. Narrowing...);
securityControllerHome =
(SecurityControllerHome)PortableRemoteObject.narrow(remoteObject,
SecurityControllerHome.class);
return securityControllerHome;
} catch (Exception ex) {
log.debug(Caughting exception trying to get remote interface);
log.debug(Message: + ex.getMessage());
ex.printStackTrace();
}
I'm using JBoss 3.2.3.
If this is not the correct way to connect to an EJB in another container, then can
someone please clarify.
The actual host IP will be dynamically configured. It cannot be in the ear. So I am
intentionally using the JNDI code to get it to look at the host I specify.
The code above is just test code to get it to work. Later I'll clean it up and make
it truly dynamic.

For one, he can have many clients access the central EJB server. Security is also increased as clients don't have access to local interfaces or the data source on the EJB server. Another alternative is to setup a timer for redoing the lookup. Of course, the clients will still be down until the timer resets, but this still offers the efficiency benefits of cached home interfaces while permitting the clients to reset without restarting them if JBoss or the applications are restarted. --- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
