[JBoss-user] Re: [JBoss-dev] tomcat4 log dir in jboss3-rc1
Is there a way to access properties from the tomcat config? If so it should
set the log dir in ${jboss.server.home.dir}/log
--jason
Quoting David Ward [EMAIL PROTECTED]:
I don't know the ins-and-outs of creating a change request, but was
wondering if for the next rc of jboss3-tomcat4 the tomcat4-service.xml
file could be changed in this way:
From this:
Valve className = org.apache.catalina.valves.AccessLogValve
prefix = localhost_access suffix = .log
pattern = common directory = ../jboss/log /
To this:
Valve className = org.apache.catalina.valves.AccessLogValve
prefix = localhost_access suffix = .log
pattern = common directory = ../server/default/log /
Currently it assumes the old JBoss-2.4.x-Tomcat-x.x.x dir structure
where jboss and tomcat/catalina were next to eachother as subdirs, which
isn't the case anymore.
Thanks,
David
As an aside, I like how the Ajp13 connector example is included in the
XML, but personally I think it would be cool to (leave it in there) but
comment it out by default. Maybe also include (but leave commented out)
Warp - and maybe the new Coyote
(http://cvs.apache.org/viewcvs/jakarta-tomcat-connectors/coyote/)? -
Connector lines.
Thanks again.

The new compiler is a complete rewrite in JavaCC, and is much faster, easier to maintain, and has error messages. I was surprised by the number of errors I found in the old parser. You guys haven't been pushing the engine enough, so to give you incentive to test the new engine I've added several new features. Error messages: This is not really a feature but as we didn't have them before it feels like a feature. JBossQL: I actually wrote two compilers a spec compliant EJB-QL compiler and JBossQL compiler. JBossQL is a superset of EJB-QL which adds support for ORDER BY. To use JBossQL you override ejb-ql declaration in your jbosscmp-jdbc.xml file with a jboss-ql element (i.e. just copy the query element from your ejb-jar.xml file, change ejb-ql to jboss-ql and add the order by clause. The BNF for order by follows: JBossQL := select_clause from_clause [where_clause] [order_by_clause] order_by_clause := ORDER BY order_by_path_expression ( , order_by_path_expression)* order_by_path_expression := ( numeric_valued_path | string_valued_path | datetime_valued_path ) [ASC | DESC] dynamic-ql: The new compiler is eye-blink fast, so I added a new query type dynamic-ql. With dynamic-ql you can generate a JBossQL query and pass it along with the parameters to the engine to be compiled and execute at runtime. To use this query you add an ejbSelect method to your bean with the following signature: return-type ejbSelectsome-name(String jbossQL, Object[] args) You must declare the query type in your ejb-jar.xml (required by the spec; just leave the ejb-ql element empty) and in your jbosscmp-jdbc.xml file override the impl with an empty dynamic-ql/ element. For more info specifying the queries, see the jbosscmp-jdbc_3_0.dtd Please, post follow-ups in the online forum at http://main.jboss.org/thread.jsp?forum=46thread=9743 -dain ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user ___ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

[JBoss-user] Re: jetty integration with apache
I was avoiding posting to jetty-discuss right away, as I didn't really do that much research (short of a few websearches) on the matter. Let me clarify though. I was hoping to make use of apache's facilities for these advanced configurations and simply proxy other requests over to JBoss. The trick would be to make sure that the url mappings look consistent from the Apache standpoint. So if there was a virtual host foo.mydomain.com, and jboss was running on mydomain.com:8080, then apache could proxy requests to a j2ee app deployed, but appear to be foo.mydomain.com. The webuser would never know about mydomain.com:8080. I know that some of this is possible with mod_proxy, but I am not so sure about the rest. I don't think that Jetty should try to incorporate all of the features and functionality of Apache. Instead, allow for JBoss/Jetty to be hooked up to Apache seemlessly and get the best of both worlds. --jason On Mon, 10 Dec 2001, Julian Gosnell wrote: Jason, As far as i know - YES You should post on [EMAIL PROTECTED] where i am sure Greg will be able to point you to the relevant doc and summarise various pros and cons.

Re: [JBoss-user] SonicMQ and JBoss
I have been working on integrating SonicMQ for the past few days... so far with out luck. It looks like there JNDI storing fluff will not bind resources from there broker to the JBoss naming service unless there is something already bound there. I hear that they are fixing that, but I am not sure when that will happen. To get around that I have played with there jclient api, to create and bind references myself (since they do not provide a configuration file to define queues/topcis/connectionFactories I needed to do that anyways). Now I am unable to get past an EUserAlreadyConnection exception that is thrown for user/pass / (which should be anonymous). This will only happen after a few connects. I am also unable to get Connection.close() to actually close, such that I could open another connection (for undeploy/deploy of an MDB). To top things off I get odd errors about a connection consumer and a session needing to be created from the same connection. That sounds fine, but wait... there is only one connect that is created, which is used to create the consumer, which is then used to construct the server session pool. So I can only see one connection. Given that there JNDI store does not work... and only provides a rather dumb error of X not bound (where X is the destination name), I am not surprised really at some of the other dumb messages that I have seen. I am surprised however that this is actually a product and that people pay money for it. --jason On Mon, 16 Jul 2001, Crothers.Dean wrote: Hi, I would be interested to hear if anybody has integrated SonicMQ with JBoss - so that SonicMQ is the MOM provider for message driven beans? thanks, Dean ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user

Re: [JBoss-user] EJB RDBMS Issue
The ideal way is to do all such database modifications thru the ejb interface only, but, unfortunately, that is not the case for me. Any inputs on problems i might face? How about, why on earth would you do something like that? What external thingy is going to delete records and leave your application in a state of confusion. Are you trying to write a Microsoft application? I don't think there is part of the EJB spec that says what will happen when some other application deletes a record, drops a table or reboots the database. If it does, let me know... I am in for a good chuckle. On a positive note, you might want to reconsider the usage of entity beans if the case truly is that you can not avoid the situation you described above.

Re: [JBoss-user] BLOB

Re: [JBoss-user] isModified Method
The method name 'getIsModified' is redundant, at least in JavaBean terms, where the prefix 'is' refers the the getter/accessor of a boolean property. Why not just use isModified()? The above would result in a property named 'isModified', not 'modified', which basically means the same thing, one is just a bit more passive than the other.

Re: [JBoss-user] Re: BLOB
I've used CMP and BLOBs with JBoss in the past. Declare the bean member variable that will hold your BLOB data as a byte[]. This will get mapped to the jdbc-type of JAVA_OBJECT. Then check (standard)jaws.xml to see that the mapping for this exists. It looks like the mapping below - BLOB(2000) - was taken from the DB2 section of standardjaws.xml. DB2 does not seem to have an arbitrary-sized BLOB type, you have to declare a maximum size for a BLOB in advance. You might want to keep this in mind when choosing a database. Postgres has a BLOB type of unlimited size. I just grep'd for a BLOB, then pasted it. I have never even used DB2, so I don't know why I picked that one =| My experience doing BLOB inserts with Postgres and DB2 and with JBoss is that it's horribly slow. I believe the database is the problem - DB2 was maybe 25% faster than Postgres but neither was fast enough for high-volume inserts, and this was with fairly small BLOBs - 10k-20k. It's possible that the overall problem was not caused by the databases but by JAWS and/or RMI overhead. Perhaps you could fix that. One thing I'd like to figure out is how to do these BLOB operations while minimizing memory use at both the client and the server. To make BLOBs work with CMP I've had to buffer the blob in memory as a byte[] member variable, both at the client and in the bean instance. Is there a more efficient way to achieve the same thing? It would be wonderful if you could declare an InputStream member and have the RMI serialization code read from this at the client w/o a lot of in-memory buffering. I know that some JDBC drivers can handle InputStream parameters on PreparedStatements, but JAWS doesn't seem to support this. As far as I know there is no way to remote an InputStream (or OutputStreams). As far as JAWS supporting InputStream params, I would say again, perhaps you could fix that. If it does exist, perhaps you could document it. Necessity is the mother of invention. If you need it, then give it life. --jason ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user

RE: [JBoss-user] SwiftMQ and JBOSS
It is possible to configure JBoss to work with a SwiftMQ provider, but NOT for MDB. You can install a SwiftMQJMSProvider, which can return the SwiftMQ defined queue/topic/connection references, but since they do not support XA or ASF you will have a world of pain trying to get MDB working with it. You could use the SwiftMQ bridge swiftlet to bridge a SwiftMQ router (or a set of routers) to a JBossMQ provider running on each JBoss node (or on just one if you like). I ran into some problems doing this when a message listener failed to process a message on the target JBossMQ queue. If this happened then the message would persist on the local queue, leaving my other message consumers (which are attached to other non-local JBossMQ providers) unable to attempt to handle those messages. --jason On Tue, 26 Jun 2001, Rajkumar Seth wrote: We tried this but the jBOSS seems to look for Queues in it own place.

Re: [JBoss-user] Distributed MDB JMS resouces inside of beans
1. If you get a XAxxxConnectionFactory and you do not have any process that actuallt starts the transaction, then you are in trouble. I can not seem to get any XA classes from the JMS RA, so I am not quite sure what you mean here. I was modeling the usage of JMS inside of a bean from some example from sun, could be the blue prints or the description of the dtd, not sure. 2. I have gotten the same type of exception, and as far as I can remember the solution is to put jbossmq-client.jar in your classpath, ie for server to server communication, put it in lib/ext (but I have not tested this for a while). I can try this, but it seems odd that this would fix the problem. I will look into it more. An overly simplified view of the system looks like this, showing three seperate pyshical machines: web server, manager node and router. The current architecture assumes a hub-spoke model for using JMS resources, so that all machines that actually make use of the JMS resources are remote, there are not MDB's running on the router. You mean the MDB:s are running on the nodes (subscribing to destinations in the router) and the session beans are also on the nodes, sending to destinations in the router? Correct. RMI [ web server ] +---+ [ manager node ] | | (SessionBean) (MDB) | | JMS Queue Resource | \/ \/ [ router ] || (real queues) I installed the resource adapter, which seems to like to be deployed rather than having a mbean entry added in jboss.jcml, which I basically copied from the main branch conf/default files. Hm, the ra must be both in jboss.jcml AND be deployed. It is confiured in jboss.jcml and bound to the correct JNDI, and then the *.ra file must be deployed (which is done be default in cvs version and 2.4). I think I was mistaken, I did have a configuration as well as a deployment. What does the deployed ra actually provide? Is it important that it be deployed prior to the configuration? My guess is not, but I want to make sure. The manager has a JMSProviderLoader installed which is using a remote hostname:port url to the router, and has the default session pool stuff. I think that the MDB bits work fine. I do not *think* that I had to change anything to get that to work, the problem I am running into is with JMS resources. Do you have a customized JMSProviderLoader, of type: mbean code=org.jboss.jms.jndi.JMSProviderLoader name=:service=JMSProviderLoader,name=MyRemoteLoader attribute name=ProviderNameMyRemoteProvider/attribute attribute name=ProviderUrlrouter:1099/attribute attribute name=ProviderAdapterClassorg.jboss.jms.jndi.JBossMQProvider/attribute /mbean My JMS provide is still called DefaultJMSProvider and I did specify for the factory loader that JNDI name was: JmsProviderAdapterJNDI=java:/DefaultJMSProvider Should I omit the java:/ ? What is ra.xml? A while back someone (could be you) said that using res-url was a hack around the lack of support for JMS resources, is that still true? For jboss 2.2.2 that is still true. In the developmen version it is not, if the ra is used. I have to admit there is still a problem with destination. To get the connection from the correct JNDI you configure a ProviderLoader, but the way both JMS and J2EE connector specifation is done I have found no way of abstracting access to the destinations out from the normal JNDI access. If jnp://router:5001/queue/WorkRequestQueue does not work, you will have to use Scot Starks solution to integrate another JNDI space into the local JNDI, but I do not think this is your problem. This seems to work. I am able to lookup destinations and get most of the way done processing until I get a TX related exception. If not what is the correct way to reference a remote connection and destination inside of the descriptor? As far as I can see it you have done perfectly right, but remote subscriptions with TX support has not been that much tested. Pleas try the jbossmq-client.jar trick and see if it works. So I should use res-jndi-name for the factory and res-url for the destination? Or isn't there some other tag that I am supposed to use for destinations. Sorry, I am still not clear on that... though I suppose it does not really matter much as long as the lookup succeeds. I am sorry to say this, but I am going on a pretty long vaication from today. I will try to check my mail of and on, the there may be long periods of silence. How long is pretty long? Days, weeks, months, years? I hope you have a good time. I do hope you get it going.

Re: [JBoss-user] JAAS JBossSX vs Application Security
Ok, then does it make sense to rely on JAAS for all of the security aspects of a system, or is the technology not mature enough yet? Specifically can it be used to limit access to methods or individual resources (such as a file or a database record marked with some identifier) based on a single user login point? Or will the application have to maintain some extra login state to achieve this level of security? --jason On Wed, 23 May 2001, Scott M Stark wrote: Reliance on static files is not a requirement; its simply the default mode.

I looked for the example and must have missed something. Also, I believe that I need to be more exact in my language, because it is easy to say something subtlety different than what I really meant. Please forgive me for my inaccuracy and any help from a knowledgeable person is greatly appreciated. I realize that you can use absolute url paths (i.e. use jnp://machine:port/somewhere) if one keeps around the url for all instances or JNDI, or in this case jnp. What I was hoping for and am still uncertain as to whether jnp supports is the ability to bind a javax.naming.Reference, which contains a javax.naming.StringRefAddr that specifies a URL federated to another name space. JNDI supports this as URLs as References for Federation. This saves complexity in the code by not having to keep urls around. Then urls can be obtained on the fly (within JNDI) and not explicitly specified. This allows for in context lookups which unites name space context with federation of name spaces. We have a very complicated problem where our name space will continue to grow and grow. It would be great to be able to stitch together name spaces using this technique. Then we have separated a configuration problem from a programing problem. Thanks again!

Re: [JBoss-user] Using JMS resources (or other resources)
For binding a subcontext from a remote server you should be able to use the Context.PROVIDER_URL to specify the subcontext and so the SubContext attribute should not be necessary. To create a local alias I would rather create a new NamingAlias mbean that created LinkRefs: mbean code="org.jboss.naming.NamingAlias" name=":service=NamingAlias,fromName=java:jms/topic" attribute name="FromName"java:jms/topic/attribute attribute name="ToName"topic/attribute /mbean That would be great. I guess this started because I was unable to lookup a QueueConnection (which I still have not had time to figure out based on the given suggestions). I just ran into another issues, where a deployed servlet needs to access a SSB and EB on a different VM. I installed a ExternalContext (very nice), then modified my code to use an InitialContext(), then get the mapped sub-context and use it for Home lookups. Sounds fine... until I start working with EJB handles... which will just use the InitialContext(), not a sub-context there of. If there was a nice way to create an alias to the default names (from the imported external context), then I would not have to perform an *magic* to restore a handle. Anyways, it sounds like a NamingAlias MBean would be a helpful feature. --jason ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user

[JBoss-user] Using JMS resources (or other resources)
Can someone point me a documentation or examples on the standard way to allow a EJB to access an external resource. I looked at the EJB spec and it was less than helpful. I saw one example of letting a bean access a JMS queue, but what about the ConnectionFactory and such? Do I need to have a seperate entry for that too? Is anyone using MDB who can give me some advise on how to go about letting an EJB access a JMS queue or topic?

That is more or less what I am going to be doing, but I wanted to know if
there was a standard way to provide the queue information to a bean. My
guess is that it should be as a resource, but I am not 100% sure.

Jason,
Why not to think about an EJB as a plain client
for JMS? There is nothing special here.
I have a helper class (sort of ServiceLocator pattern)
which I'm using either on clients (servlets) and server (EJBs):
/
* creates query session
/
private void getQueueSession() throws BmxServerException
{
if ( qsession != null )
return;
// !!!provider specific!!!, must be got from properties
QueueConnectionFactory queueFactory = null;
try
{
queueFactory =
(QueueConnectionFactory)context.lookup("QueueConnectionFactory");
}
catch (NamingException ne)
{
throw new BmxServerException(ne, BmxError.InternalError);
}
try
{
QueueConnection queueConnection =
queueFactory.createQueueConnection();
qsession = queueConnection.createQueueSession(false,
Session.AUTO_ACKNOWLEDGE);
}
catch (JMSException jmse)
{
throw new BmxServerException(jmse, BmxError.InternalError);
}
}
/
* sends message into queue
/
public void sendXmlMessage(String queueName, XmlDescriptor xmessage)
throws BmxServerException
{
getQueueSession();
try
{
Queue queue = (Queue)context.lookup("queue/" +
queueName);
QueueSender sender = qsession.createSender(queue);
TextMessage tmess = qsession.createTextMessage();
tmess.setText(xmessage.toXmlString());
sender.send(tmess);
}
catch (Exception e)
{
throw new BmxServerException(e, BmxError.InternalError);
}
}

Re: [JBoss-user] Using JMS resources (or other resources)
Thanks... so would I use something like this: resource-env-ref resource-env-ref-namejms/StockQueue/resource-env-ref-name resource-env-ref-typejavax.jms.Queue/resource-env-ref-type /resource-env-ref to get at the queue/topic information to use with the connection factory as configured below? --jason On Thu, 12 Apr 2001, Scott M Stark wrote: A ConnectionFactory is a resource factory and the spec talks about JMS being located by convention under the java:comp/env/jms context.
