RE: [JBoss-user] JBoss example problem - new to J2EE
Thank a lot Adrian it helped me. I have just one more question. In JBoss IDE Fibo tutorial there is binding to "ejb/tutorial/Fibo" and that is exactly what JBoss shows when it deployes application. But when connecting to client servlet, client looks for the "java:/comp/env/ejb/Fibo" client call is succesfull even if the if the Fibo ejb is bind to "ejb/tutorial/Fibo". What is interesting to me is that from the servlet i`m able to make an instance of Fibo ejb, but when looking up from for example HelloWorld client I`m not able to get the bounded object. when looking up "java:/comp/env/ejb/Fibo". so my qestion: Where in the depl. descr. is told to bind Fibo bean to "java:/comp/env/ejb/Fibo".

[JBoss-user] ROOT.war
If I take jboss 3.2.2 out-of-the-box and rename server/default/deploy/jmx-console.war to ROOT.war and I try going to the url http://localhost:8080 I get a “HTTP Status 500 – No Content configured to process this request” response. I can then go to http://localhost:8080/ROOT and it works fine (goes to the jmx console as expected). What is the additional configuration I need to do in order to define a root context? I couldn’t find anything in the JBoss documentation which we purchased which describes how to do this. Any pointers here would be greatly appreciated. Thanks, Rob
RE: [JBoss-user] JBossNET hot deploymentproblem(ClassCastException)
I'm not sure if this is the same thing, but I ran into an issue in axis where it
caches the classloader of the first webapp which calls into axis. I tracked it down to
the method getClassLoaders of AxisProperties.java:
private static ClassLoaders getClassLoaders() {
if (loaders == null) {
loaders = ClassLoaders.getAppLoaders(AxisProperties.class, null, true);
}
return loaders;
}
Hope that helps.

RE: [JBoss-user] Re:[JBoss-user]ClassCircularityError-QueuedPessimisticEJBLock$TxLock
That makes sense. Thanks. In any case, we've found a way to workaround this issue which works for our purposes. Basically, we've moved everything from jboss/server/default/lib to jboss/lib and moved all the jars from all the sars to jboss/lib. I realize that this basically defeats hot-deploy of any of the sars, but it works for us since we're running a (very) stripped-down deployment of JBoss. (This is our first release in which we are moving from straight Tomcat to JBoss+Tomcat and are in the process of gradually migrating to J2EE technologies). Currently each jar in jboss/lib much be explicitly called out via the property jboss.boot.library.list. If I were to make the changes to ServerLoader such that it defaults to the whole directory, is this a patch which you would consider absorbing? If not, no big deal, we have a "launcher" app which we can use to bootstrap the whole thing.

Thanks - I really appreciate the help. Also, is this problem something which you have worked around for 3.2.2? (I'm still seeing it in 3.2.1.). Or is this something which can't be solved until Sun fixes their stuff? I noticed that there is a UnifiedClassLoader2 which looks like it solved the original deadlock problem by locking the UnifiedLoaderRepository from the loadClass method. It also looks like it didn't have the ClassCircularityError issue that UnifiedClassLoader3 has (since it never relinquishes the ClassLoader lock via a call to wait). What was wrong with this approach such that you switched to UnifiedClassLoader3?

RE: [JBoss-user] Re: [JBoss-user] ClassCircularityError-QueuedPessimisticEJBLock$TxLock
Thanks for your quick response. That helps a lot.
I have a couple more questions though...
In the parent-delegation model, as long as the class of the shared
object is present in a parent class loader of the two classes which are
sharing the object, there should be no need to marshall the object,
right? Is it just that it's too unwieldy to factor out the shared
classes and place them in a parent class loader?
Also, what is the difference in functionality between a)having several
UnifiedClassLoaders which are part of the same UnifiedLoaderRepository
and b)having a single instance of a classloader which is a subclass of
URLClassLoader which allows url's to be added dynamically, hence
supporting hot-deploy? In my previous email I was thinking that the
advantage was you could redeploy a class without having to redeploy the
classes which depend on it, but as you said any classes hard-referencing
it would need to be redeployed anyway.
Thanks,
Rob

Re: [JBoss-user] ClassCircularityError-QueuedPessimisticEJBLock$TxLock
Can someone please point me towards some documentation which describes the advantage of the UnifiedClassLoader model over the tree-based class loading model? We purchased the JBoss documentation and all it says in the administrators guide is that “JBoss 3.x employs a new class loading architechture that facilitates sharing of classes across deployment units”. It also mentions that prior to this architecture, MBeans were not hot-deployable. Is this basically saying that it allows you to hot-deploy a component without having to re-deploy those components which depend on it and its classes? Any help here would be appreciated. Thanks, Rob

Re: [JBoss-user] jetty max form size reached?
We ran into a similar problem. Not sure if it's related to what you're seeing, but Jetty added a parameter to guard against certain DOS attacks that limits the size of form data returned. Setting the "org.mortbay.http.HttpRequest.maxFormContentSize" system property allows this to be configured. We use the following to our JBoss startup script: -Dorg.mortbay.http.HttpRequest.maxFormContentSize=100 so we are limited to about 1M of form data. rob. - Original Message - From: "Frank Morton" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, April 03, 2003 1:13 PM Subject: [JBoss-user] jetty max form size reached? > Using jboss 3.2.0RC2/jetty under MacOS X with JDK 1.4.1. > > I have a large form with 2095 items.

[JBoss-user] JBoss CMP/Sybase limitation
Hi - Sybase ASE has a limitation of 250 ANDs/ORs in a select. It also has a limitation of 250 elements inside of an IN. We've encountered a problem with the way that JBoss CMP pulls large sets of data from the database because of this limitation. CMP engine first pulls all of the primary keys and then does a second query that looks like "SELECT * FROM TABLE WHERE primary_key=? OR primary_key=? OR primary_key=? OR ..." The problem is that when the result set contains more than 250 primary keys, the query that JBoss generates causes Sybase to throw an SQL exception because of the limitation. Any way around this?

We are using JBuilder 7 and jboss 3.0.2 together. Someone else mentioned the protegra plugin, which we tried at one time, but we settled on the JBoss Opentool, which is an open source equivalent. Here is a link to it: http://sourceforge.net/projects/jboss-opentool/ It works quite well - all the deployment descriptors are automatically populated, including those for CMP entity beans. To configure JBuilder 7 to work properly with JBoss using the JBoss Opentool, just do the following: 1.) Drop the opentool jar file into the appropriate jbuilder directory (specified in the install instructions) 2.) Go to Tools->Configure Servers... 3.) Click "JBoss 3.x". 4.) Click "Enable Server". Make sure all the directories are pointing at your jboss installation. 5.) On the "Custom" tab, make sure that the jboss installation directory is correct. 6.) Under "JBoss configuration to use" pick your configuration (default, all, minimal, etc). 7.) Go to Project Properties->Server. 8.) For "Relationship between server and services" check "Modular services provided by different servers" 9.) For "EJB" and "Deployment", pick "Jboss 3.x". 10.) For "JSP/Servlet" pick "Tomcat 3.3" That should do it. Let me know if you have any further problems. Good luck!

RE: [JBoss-user] Re: ClassCastException on redeploy of .ear
I had this exact problem, but with an ejb jar instead of an ear. I could deploy the jar exactly once and it would work fine. After that I could never redeploy it without it permanently breaking. The only way to fix the problem was to shut down the server. After reading this message, I checked my jar and found that a jndi.properties file I use for client-side access had sneaked into the file. The contents of the jndi.properties were valid, but it shouldn't have been in the jar file. After removing the jndi.properties, everything works fine. Question - is the behavior described above a bug or a feature that we were accidentally misusing? It would seem to be a fairly severe vulnerability in the server that an errant jndi.properties file in a jar file can permanently break the server. Any insight? Thanks.

[JBoss-user] Auto-increment primary keys and CMP
Hi - I have a table that has a NUMERIC primary key that is defined as an IDENTITY key. The primary key column is defined such that the database automatically sets the primary key on insert to the next incremental value. The user is not allowed to set the key to any value or the database will return an error. My problem is that I have defined a CMP bean that maps to this table, but I cannot get a create to work. If I call a create which includes the primary key, the database throws an exception because I am not allowed to set the value. If I call a create method that does not take the primary key, the database throws an exception because JBoss is trying to set the primary key to null. My question is - is there any way to tell JBoss that this primary key is managed by the database and thus should not be written to? How do people typically handle working with tables with identity keys? By the way, I am using JBoss 3.0.2 and Sybase Adaptive Server Enterprise 12. Thanks.

Re: [JBoss-user] Erratic -- jboss3.0 on linux
most likely a vm problem. java on linux is a bit of a problem. many VMs (including the latest 1.4.1 VM) are very buggy. what vm are you using? try switching (e.g. from 1.4.1 to 1.4 or 1.3 or try the blackdown ports or ibm vms instead of sun's). it's really trial and error as one VM might run flawlessly with one application server and another one won't and it might be vice versa with a different application server. sad but that's how it is. hth robert On Friday 20 September 2002 08:51, Arijit Ghosh wrote: > Hi, > > Jboss3.0 on Linux is behaving erratically.

[JBoss-user] LdapLoginModule Bug: Problem with empty passwords
Using the LdapLoginModule, supplying an empty password for a user causes
an anonymous bind to happen. This is documented in the JNDI
documentation here
http://java.sun.com/products/jndi/tutorial/ldap/faq/context.html.
Read the section [ Why does the LDAP provider ignore my security
environment properties if I do not set the Context.SECURITY_CREDENTIALS
("java.naming.security.credentials") property or set it to the empty
string? ] . Supplying an empty string as the credentials causes the
context to set the SECURITY_AUTHENTICATION property to "none" and then
does an anon bind.
If your Ldap server is set to except anon connections this is a problem
for the LdapLoginModule. Supplying the empty password does not cause an
exception to be thrown and the uid and the roles for that uid are passed
back.
Here is the patch for this as well. The only thing that needed to be
changed in the method was to check to make sure the password is not an
empty string as well as null.
protected boolean validatePassword(String inputPassword, String
expectedPassword)
{
boolean isValid = false;
if( inputPassword != null && !inputPassword.equals(""))
{
try
{
// Validate the password by trying to create an initial
context
String username = getUsername();
createLdapInitContext(username, inputPassword);
isValid = true;
}
catch(NamingException e)
{
super.log.error("Failed to validate password", e);
}
}
return isValid;
}

[JBoss-user] Integrating Non-JMS Messaging with JBoss
Hi - We're using a messaging product called TIBCO Rendevous that I would like to integrate with an application running on the JBoss server. TIBCO does have a JMS product but we have decided not to use it for cost reasons. My question is - what is the best way to integrate non-JMS messaging with a J2EE application running on the JBoss server? Can I somehow define my TIBCO listener class as a service that JBoss will start up and run for me on the server itself? Or does my listener need to be an external client application which then makes calls into the JBoss server? I suppose writing a JMS - TIBCO adaptor is another possibility, but I imagine this would be quite a bit of work. Any ideas? Thanks.

Hi -
I am trying to deploy a very simple CMP bean which I created for an existing
table in our Sybase AS Enterprise 12 database. An exception is thrown every
time JBoss tries to check a connection in to the connection pool. This
exception happens when the bean is deployed and again when it is called.
Has anyone seen this error before/know how to deal with it? Thanks.

Hi -
I'm just starting to try out JBoss and I'm having some problems just doing a
simple name lookup. I've confirmed that JBoss 3.0 is running without any
errors in its startup log.I have successfully deployed a simple test
bean to the server. I have a tiny little client application that is
basically just trying to make a call to a test bean on the server. Here is
the snippet of code that is failing:
---
TestHome home = Naming.lookup("testBean");
---
Here is the exception I get:

Can anyone point me in the right direction?I've tried this with Jboss
running on both a Linux box and a Windows box - jdk1.4.1 and jdk1.3.1
respectively. Thanks.

[JBoss-user] Shared caching among different EJBs
Hi everybody, I have spent the last few days pondering and working on some EJB related stuff, without getting where I wanted to. Now a friend helped me out, but I do not know, if the proposed thing is a good solution or not. I am in need of something like a local context, into which I can store data, for shared Access by several of my Beans. The idea is to query the database for some parameters, calculate the result from this data, and store this data for a certain period of time within the jvm. Actually it sounds like the ideal job for a session bean, but the data should be accessible by several beans of my business logic, and not just one client. The approach suggested by a friend of mine seems to be plausible, though I do not know, whether it is permissible. I have created a stateless session bean, which in turn accesses static methods, of a class, which in turn has a static field, which acts as Singleton, into which, and from which I can take the data I need. If the data is not within the context, it can be requeried and recalculated, as the need arises. Thus I have a local cache, which is neither passivated, and which I can access from any beans within the same jvm. What I would like to ask now, are there reasons not to go with this solution. Are there other solutions, to achieve the same result? -- Another thing, though not that important to me, a different thing that I have tried, but which I did not get to work, was to put an RMI Object into the JNDI, which would be done at start up time, via a MBean. But I failed to accomplish this, and fear that this is beyond my skills for the time being. RMI Server runs ok, by itself, but when I try to instantiate it and bind it from the MBean I get a NoSuchObjectException when I try to access it from a client. If anyone happened to have done this already, I would of course be interested to know what I did wrong. Thanks in advance Robert Herzig Diese Nachricht wurde über tower media 1 gesendet Ihre 1.

not occur with Netscape 6.2 or IE 6.
My servlet creates or retrieves an existing bean to which data is saved
from form data posted:
HttpSession session = request.getSession(true);
AppInfo app = (AppInfo)
session.getAttribute("ApplicationInfo");
if (app == null) {
app = new AppInfo();
session.setAttribute("ApplicationInfo", app);
}
app.setFirstName(request.getParameter("fname");
Then the servlet redirects to another servlet that displays the result:
response.sendRedirect(
response.encodeRedirectURL("/" + nextPage));
I've also tried using (with the same unfortunate results):
response.sendRedirect("/" + nextPage);
The display page trys to find the saved bean.
(it fails - but only in Navigator 4.08):
HttpSession session = request.getSession(true);
AppInfo app = (AppInfo)
session.getAttribute("ApplicationInfo");
if (app == null) {
app = new AppInfo();
session.setAttribute("ApplicationInfo", app);
}
The problem is, after an unusally long delay (several seconds) it creates
a blank instance of my bean because it did not find the one saved as
"ApplicationInfo".
I've also tried turning the browser's cookies off. No luck there either.
Can anyone help?
Thanks in advance!!!

RE: [JBoss-user] Stateful session remove?
I think the passivation problem is not a serialization problem, as it works sometimes (in fact most of the time - in our case around 550 out of 600 times). I think it is some sort of coordination/ synchronisation problem between the Cache and the container.

RE: [JBoss-user] Stateful session remove?
Same problem here - started as on 2.4.0. Does not happen all the time, seems to be some sort of synchronization issue between the LRUEnterpriseContextCachePolicy and the SessionPersistenceManager ... I could really figure out what's wrong (hard to debug, because it only happens sometimes) - I ended up changing the cache policy to NoPassivationCachePolicy for statefull session beans. In standardjboss.xml, in the stateful session bean section, change to org.jboss.ejb.plugins.NoPassivationCachePolicy Of course you stateful session beans won't get passivated anymore - which may or may not be a problem. If anyone has a fix to get the passivating one working properly, please let me know.

RE: [JBoss-user] Performance...
Lots of stuff (been doing Java for a while ;-), but here are some techniques (in extremly short format) when you have gc problems. 1) Monitoring Find out what does not get collected. Either use a tool like OptimizeIt - but I find them a bit clunky to use or do it "by hand": Identify your "key" objects - the ones which you need to create for every page transition / request and instance count them (+1 in the constructor -1 in finalize) and make the info available at any time (we have a "MemoryStatus" servlet / dump thread). Finalizing does not mean it gets collected, but not being finalized means it won't get collected. You need to be somewhat "strategic" on which objects to keep track of so the monitoring does not slow your app down. 2) Write "Destructors" Once you know what does not get collected, fix it. For frameworks I found it useful to have a _clean() method which gets called from the framework to unhook references (especially to cut circular references) Especially key an eye on hashtables, vectors and any other reference hugging data structures and clear() them when they are no longer needed. 3) Write a GC kicking / monitoring thread Search this list for "GC kicking bean", I posted the code for an MBean for Jboss a few weeks ago. Doing all this works fine for server side stuff. Last time I was involved with client side (swing) Java was two years ago and it was almost impossible to make Swing not leak - the API just did not allow to clean up after you are done (e.g. removing all listeners was often not possible) and the gc was not good enough to collect the complex structures. This might have changed with 1.3 - I don't know. Comments anyone? Hope this helps. Am interested in any futher approaches.

RE: [JBoss-user] Performance...
Jo napot kivanok (this is as far as my Hungarian will go) We have a very similar setup Single CPU P4-1.4G, 1G RAM, fast SCSI disk running RH 7.1, SUN JDK1.3.1, Apache, Resin, JBoss2.4 and Postgres. This setup runs around 50 concurent users mucking around with the web app easily (we did not push it further as we only use it in-house at the moment) and we have it running for weeks with consistent response times. We talking hundreds of thousands of bean method invocations and millions of SQL queries. Due to the nature of the app, our session are all pretty long running (whereas yours sounds like a couple of pages per session app, right?) The only thing with Postgres is to VACUUM it periodically if you have a lot of updates (we do it every 10 minutes which takes around 3 secs). We have around 30 beans - jboss sits at about 48M (up from 39 for JBoss2.2) and our servlet engine at about (25) - however we did a lot of work to make sure our app logic gc-s properly.

[JBoss-user] RE: freezing
Boris, I don't want to get into this shit fight - jBoss (as any piece of software) might have bugs in it, but not enough to be obusive on this list. And threads on the newsgroup to use some other server are a waste of everyone's reading time. Back to the question below - we use jBoss2.2.2 standalone (no in VM servlet engine) as a backend to resin against postgres on RH Linux 7.1. We deploy it internally and ran stress tests which created around 50,000 beans (and 500,000+ dependend objects and BMP SQL queries, 100,000+ connections going in and out of the pool) and it works like a dream for us - I am not saying we did not encounter any problems or it works in all situations - it is a distributed system afterall and they just like to blow up all over the place if you are not careful. The only way to get the problems you describe fixed is to do the work. Switch on logging and narrow down the problem. Take Beans and MBeans out and find out why it breaks. Once you know where it breaks, you have three options 1) work around it 2) post it to the newsgroup 3) read the code and find out what's wrong (this way you usually end up finding out why your app breaks) and then post it to the newsgroup or fix it I usually opt for 1) - this might require 3) to understand how to and/or what's wrong with your app. If that's all too hard - pay BEA 30,000 and they will do the work for you. So - for your "hanging" problem. Build the smallest bean and client to reproduce it - post it to the newsgroup, trace through the code ... I am not saying it is easy. But it is possible - try finding out why some proprietary software tool does not quite do the right thing ... And remember - have fun digging through the code. There are some clever pieces of coding in jBoss, well worth looking at anyway ... Robert. > Hello, Robert. How did you get away with that freezing > problem?

RE: [JBoss-user] Need more examples contributed by others
Cool beans! I'd also like to hear success stories on how people are integrating jboss with other open source projects. For example, from things a little more exotic than the typical Apache/Tomcat/Jboss combo. I haven't spent much time with Castor but it looks interesting. I don't know what Lucene or jmoz is. My little company is trying to levarage as much as we can from the open source world. Of course we will have to donate back to the open source cause as much as we can... BTW The JBoss/Jetty combo is really cool. Further, it is my understanding that the new jboss forum is based on Jboss/Jetty/Jive. It inspired us to think about creating some forums of our own.

I think it would be an absolute godsend if more people contributed to the documentation, especially in the area of concrete examples. I know the core JBoss team is really busy, so it I would image they would welcome any such efforts. Often the topic of the questions belongs more appropriately to a basics of J2EE, J2EE configuration and security but it can be very confusing to know where the problem exists: Where did I go wrong? I for one hope to write some docs for this project very soon, but I'm afraid it would be the blind leading the blind right now! (But thats a poor excuse...)

[JBoss-user] JSP to EJBs results in a security exception (principal=null)
> I have the same problem, except servlet to EJB is always failing for me. From: "Alexander Sparkowsky" <[EMAIL PROTECTED]> To: "jboss-user" <[EMAIL PROTECTED]> Date: Tue, 7 Aug 2001 09:02:40 +0200 Subject: [JBoss-user] JSP and security domain? Reply-To: [EMAIL PROTECTED] Hi, I've an application which consist of a main servlet and some JSPs for representing data. I secured the servlet and put it into a security domain to be able to access EJBs. When testing my application using jboss 2.4.0 build 26 I ran into trouble when JSPs tried to access EJBs direct. It seems as if the JSPs aren't in the same security domain as the rest of the application, because every access from JSP to EJBs results in a security exception (principal=null). Every other access (e. g. from the scured servlet) works fine (principal=xxx). How can I declare the security domain for my JSPs? They are in the same .war as the servlet-descriptor (web.xml/jboss-web.xml) which contains a security domain statement. Thanks.

[JBoss-user] Faulty Seg Faults?
I've recieved a few of those nasty seg faults today like: ./run.sh: line 27: 14855 Segmentation fault java $HOTSPOT $JAXP -classpath... Each time it happened was during start-up. The first time it happended was when I made some XML syntax errors in my in my jboss.jcml file. The second time was when there was a problem connecting a datasource to postgres because postgres failed to start (due to an unclean postgres shutdown the time before). Also, I regulary copy stuff to deploy w/ and w/o the server started without any problems. I have a hunch that because it seg faults only during startup, it may have something to due with errors occuring before the full system is bootstrapped. Instead of displaying a usual exception, it seg faults. Maybe it is trying to call some callback routine that does not exist yet or something. My enviroment is RH 7.1 with the latest patches (Kernel 2.4.3-12 on an i686) Sun Java J2SE and HotSpot 1.3.1-b24, mixed mode (whatever that means!) with the LD_ASSUME_KERNEL=2.2.5 enviroment variable set (as recommended by the redhat install instructions) which has something to do with 2.4 can do real threading but the jdk isn't built for this???

[JBoss-user] Deployment Questions
I've been reading through the manual but serveral things are still fuzzy to me - FACTS: I'm trying to deploy a web app with the following config: Linux 2.4, Sun Java JDK 1.3.1 Apache 1.3.20, with mod_jk JBoss-2.2.2_Tomcat-3.2.2 (Embedded Tomcat) My app consists of static html, jsp's, servlets, session & entity EJB's. Currently I've been dropping .war files in JBoss's deploy directory and manually copying static content. QUESTIONS: 1. Is there a better file packaging scheme, i.e. .ear files? 2. Do I need to drop a copy of the .war file into any of tomcat's directories? 3. How about .ear files? 4. Should I split the components into seperate packages based on component type? 5. Are there directories that my web designer can drop .jsp files into using DreamWeaver Ultradev? 6. Any tips on what files go into what directories for both packaging and deployment. I really appreciate any suggestions and/or referals to other documentation! Thanks!!! ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user

Wrong spec. See Servlet 2.3 (PFD 2), SRV.9.7.1 (Dependencies on Extensions).
It goes for a few paragraphs, but the relevant one is:
It is recommended that Application developers provide a META-INF/MANIFEST.MF
entry in the WAR file listing extensions, if any, needed by the WAR. The
format of the manifest entry should follow standard JAR manifest format. In
expressing dependencies on extensions installed on the web container, the
manifest entry should follow the specification for standard extensions
defined at
http://java.sun.com/j2se/1.3/docs/guide/extensions/versioning.html.
Basically the J2EE spec says that the valid targets for the Class-Path are
JAR files. So, a WAR file could refer to an EJB (or a library jar) this way,
but the EJB (or library jar) can not refer back to the WAR in this fashion.

Umm... not right now. :) Of the three servers I've played with recently,
JBoss is the first to use the Extension mechanism correctly (read: at all)
> That is your interpretation.
I'll stand by the interpretation... in any case, I don't believe that JBoss
is not spec compliant. There's nothing in the Extension mechanism to talk
about how you get _back_ to the calling classloader, and it is
fine-and-dandy for the Extension to be loaded on a separate classloader.

The Servlet spec requires that the class is in the class path. Accordingly, in the META-INF/manifest.mf file for myWeb.war, there is an entry that reads thusly: Class-Path: myLib.jar The reason this is built like this is that the servlet is a generic piece of infrastructure which uses locally provided classes (instantiated by reflection) to implement a Model2 architecture. As we expect to deploy several web apps (each in their own WAR) in the final EAR, we have the servlet in an external library JAR. All perfectly legal according to the J2EE spec. Sorry if that wasn't clear before. :) Anyway, to get back to the core of the problem: Is there an object that the servlet has access to (such as the ServletConfig or the ServletContext) that is certain to be instantiated by the classloader for the Web App? If I can get such an object, I can use its classloader to instantiate the other classes.

[JBoss-user] Problem with classloader, servlets, and EARs.
I'm hoping someone can shed some light on a problem I'm having. I have a EAR structured like somewhat this: (names changed to protect the innocent) myApp.ear |--- myLib.jar | |-- myServlet.class | |--- myWeb.war |-- WEB-INF/web.xml |-- WEB-INF/classes/myClass.class When myServlet.class loads, it tries to instantiate (by reflection) an instance of myClass. However, it gets a ClassNotFound exception. My tentative guess at what's going on is that myServlet is being found by the classloader for the EAR. This doesn't have access to the contents of the WAR file, so it doesn't see the web classes. This implies that I need to get hold of the classloader for the web-application. Does anyone have any idea on how to do this? I'm stuck. (Yes, the code works fine if I move myClass.class out to myLib.jar, or if I move myServlet.class into the WAR.

[JBoss-user] I'm I tripping? Or does JBoss 2.2.1 call ejbStore() on my ejb way too often??
The JBoss container seems to call ejbStore() on my BMP-style entity bean very often. This results in multiple unecessary UPDATE's to my base table. When does JBoss decide it should call ejbStore()? I must be doing something wrong! Any ideas would be very much appreciated! ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
RE: [JBoss-user] DEAR JBOSS USERS
We are very happy with it - we are currently using 2.2 on jdk1.3.0/Linux against postgres/Linux. We run resin as the servlet engine in separate VMs plugged into apache. We have about 10 entitiy and 20 session beans and written a fairly substantial web app on top of it and it works like a dream. We have a reasonable amount of data in the database (around 100,000 rows in the biggest table). I have to add that we are only using the "core" EJB features (entity and session beans) and took out all the other stuff (MDB, Tomcat/Jetty integration, soap, ...) We are not in production yet but reasonably close to it - we have done some load testing and it is looking good. The hardest part is (or used to be in PRE2.0) getting it to work in the first place ... but in comparison to say oracle it is quite easy (in comparison to postgres, it is quite hard). You need to spend a bit of time setting up a productive development environment - I recommend a IDE of your choice (not entering this discussion again) and a good build tool - we use ANT (and it rocks). The hot deploy of jboss and the automatic checking of newer class files of resin makes the develop / compile / run cycle really quick. Ok 'nough said.

[JBoss-user] Problem with NoClassDefFoundError
I've been banging my head against this problem for the last few hours, and I'm calling for help. I've got an EAR file, with multiple EJBs in it, and a common library jar. It looks sort of like this (names changed to protect the innocent): PSNG.ear |-- PaymentCommandExecutor.jar |-- PSNG.jar The EJB jar has a manifest file with a Class-Path entry of PSNG.jar. Both the jar file and the EJB have been assembled from the same set of compiled classes, so everything is in sync. When I got to deploy the sucker, I get the error listed below.

[JBoss-user] Problem with assumeJavaPrefix
How do I disable assumeJavaPrefix? My situation is this: I have a JMS Factory defined and bound to a location in my global JNDI namespace. I wish to access this factory from an EJB. I ended up with a jboss.xml file for the EJB like this: PaymentCommandExecutor PSNG.PaymentCommandExecutorHome Standard Stateless SessionBean jms/PSNG-JMS-Factory JMSFactory jms/PSNG-JMS-Queue JMSQueue JMSFactory PSNG.JMSFactory JMSQueue queue/PSNG.JMSQueue I can confirm that PSNG.JMSFactory and queue/PSNG.JMSQueue are correctly bound, by inspecting the JNDI tree. When I go to deploy the EJB, I get the following warning: [Container factory] res-jndi-name(PSNG.JMSFactory)does not start with java:/ and assumeJavaPrefix is true [Container factory] res-jndi-name(PSNG.JMSQueue)does not start with java:/ and assumeJavaPrefix is true Poking around in the code, I saw that if assumeJavaPrefix is true, then all the JNDI entries are meant to be in the java: namespace. This isn't the case for me, and I'd rather it wasn't, so what I need to know is how to set it to false. Any ideas?

I don't want to steal Jim's thunder, but I thought I'd jump in and answer this as I've spent a lot of time looking at this recently. In most app servers, you would still have the overhead of the RMI call. In addition to this, your parameters would be passed by RMI conventions (meaning you get a copy of the object, not the object itself).(*) In addition to this, you are forced to expose all your EJBs, which can give you a cluttered view of the system. With local interfaces, you lose the RMI call, you actually pass the parameters as per normal Java conventions, and you don't have to worry about remote exceptions. Also, by deploying some of your low-level entity beans purely locally, you provide a cleaner public view of the system, without losing flexibility. Also note that session beans can be accessed via local interfaces. This means that you can use session beans as purely pluggable components, accessed via a factory pattern. Anything that you would like to be configurable or separately upgradeable in your system can be, simply be converting it into a local stateless or stateful session bean. This gives you a lot of flexibility in your design, and is significantly more powerful a concept than the dependent objects it replaces. > Are security/transaction/etc... still managed by the > container if you access > a bean via a local interface? Yes. > Does anyone know if MVCSoft supports local interfaces? This I don't know. I doubt it though... the new spec version is still very new. Robert. (*) Some web servers "optimise" the RMI call out of the way when accessing something in the same app server.

RE: [JBoss-user] petstore 1.1.2
Yes the only reason you should need it and you can work around it is because they use a j2ee RI class for deployment in the Ant rules. This can be easily worked around by simply building a war and not worrying about that class. That's the only reason you should need to reference j2ee.jar from RI otherwise, the jars you need should come with jboss. you just have to edit the j2ee.path stuff to make it reference the jboss files. I recently ported 1.1.2 to Weblogic 6 and I simply passed -Dweblogic.home= through as a property when invoking ant from build.bat and refereneced it from the build.xml files. > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of Cuong Tran > Sent: Tuesday, May 22, 2001 10:28 AM > To: [EMAIL PROTECTED] > Subject: Re: [JBoss-user] petstore 1.1.2 > > > > You need j2ee sdk to build it. > > --- mroosendaal <[EMAIL PROTECTED]> wrote: > > Has anyone installed and deployed the new petstore 1.1.2, when i ran the > > build.bat from petstore i got loads (60) of errors. > > > > I have jdk1.3 and jboss is running, it shouldn't be more then > just executing > > the build .bat in de petstore/src/petstore/src, shoud it? > > > > Maarten > > > > > = > Cuong Q.

RE: [JBoss-user] petstore 1.1.2 deployed successfully
Did you maintain separate jars in the .ear or use one big jar for the ejbs? Also, does Jboss allow you to generate the stubs and skels are deploy time like Weblogic 6.0 with ejbc? In the case o Weblogic 6.0 you cannot do this because there are class resolution issues across the jars and their dependencies with ejbc at deploytime and there's no way to define the order in which ejbc should process the .jars in the .ear as deploy time.

1.1.2 should be easier than 1.1.1 to setup. I got 1.1.2 working in Weblogic 6.0 ok. The populateservlet stuff should be simple if you setup your datasources and connection pools correctly. you also have to make sure your resource-refs resolve to the appropriate JNDI names. The best thing to do is to get 1.1.2 running on the reference implementation and then look at the deploy tool to see all the names and associations that exist and mimic these in what ever container you're trying to get it running in. > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of Shriver, > Ryan > Sent: Thursday, May 17, 2001 6:43 AM > To: '[EMAIL PROTECTED]' > Subject: RE: [JBoss-user] dear god, please help (petstore 1.1.2) > > > > After spending two full days trying to get Petstore 1.1.2 to deploy on > > Jboss, it would be so great if someone with experience > > could write up a > > quick tutorial. > > > > I've followed the instructions from the 1.1.1 install, and > > have tried many > > things on my own, but having just started with EJB/JBoss, > > this is driving me > > crazy. > > > > This should take an experienced user less than an hour, and > > it would save > > days for all of us just learning EJB/Jboss. > > I got Petstore 1.1.1 deployed and working in JBoss.

RE: [JBoss-user] Re: JAWS: Is this a bug, or is there another rational
I think streaming into postgres only works with the "Fasttrack" API. Have a look at the postgres JDBC doc - there are a few examples how to do it and I played around with it a while ago and it worked well. I think you have to downcast the statment and then there is a large object API. As far as I remember, the methods on statement dealing with streams are not implemented - have a look at the source.

[JBoss-user] Deploying the Petstore app on Jboss.
Well I downloaded the 1.1.1 patch and fortunately I already have the 1.1.1 source release from javasoft. Despite it no longer being available today. I look at the README in the patch and it points me to a URL that's no longer valid http://www.jboss.org/newsite/documentation/petstore-1.1.1-01.html I would like to see a number list of steps needed to deploy the Petstore on jboss.

[JBoss-user] weblogic ejb descriptors vs jboss descriptors
I've just been recently looking at Weblogic 6.0 and noticed that there's very little that gets you to a weblogic-ejb-jar.xml short of editing the file by hand yourself. I wanted to ask folks on this list if the process is any easier on jboss. I was looking at getting the petstore 1.1.2 release working on Weblogic but it's gonna take a lot of hand creating weblogic-ejb-jar.xml files. Has anybody got 1.1.2 working on Jboss yet? Is there any way to easily get from the RI's ejb-jar.xml to the proprietory descriptor that jboss needs to define jndi names and security roles etc? ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user

man nohup Cheers, R.

The nohup utility can be used when it is known that command will take a long time to run and the user wants to logout of the terminal; when a shell exits, the system sends its chil- dren SIGHUP signals, which by default cause them to be killed. All stopped, running, and background jobs will ignore SIGHUP and continue running, if their invocation is preceded by the nohup command or if the process programmat- ically has chosen to ignore SIGHUP. > -Original Message- > From: Juan Arraiza [mailto:[EMAIL PROTECTED]] > Sent: Thursday, May 03, 2001 19:03 > To: [EMAIL PROTECTED] > Subject: [JBoss-user] problems launching JBoss2.2.x from a user shell > > > Hi all, > We are founding trouble when launching JBoss2.2.x as a background > process from a user shell in Solaris 2.6.

RE: [JBoss-user] What happens at 6 hours and 35 minutes?
Not sure whether this will help, but here are a couple of suggestions ... Write a thread which dumps memory usage, calls System.gc() and dumps the time it takes into a file every 10 seconds or so. This might tell you whether the gc makes the JVM die. Next step is to implement a "state logging" singelton into which you call whenever you enter/leave "suspect parts" of the code and make the thread dump the state as well continously ... this might help to narrow it down. Does the crash depend on load, is it always after thye _exact_ same amount of time? Overall yours is a pretty nasty problem, as you'll have to wait 6 hours to see whether it makes a difference |-( Good luck.

RE: [JBoss-user] JDBC Sybase configuration?
The url format is the same as that you would use to connect to the database from any java program it should look something like this: jdbc:sybase:Tds:XXX:YYY?ELIMINATE_010SM=true where XXX is the address of the database (i.e. along the lines of mydb.mycompany.com) and YYY is the port you should be connecting to. The ?ELIMINATE_010SM=true part of the URL is optional. It turns off a Sysbase warning message that is generated because the databases we connect to don't support all of the features of JConnect, this isn't a problem in itself as it works fine. However without the flag to turn the warning off Jboss will catch the warning, decide things don't look too good, and ignore this dataSource (so you would never be able to connect to this Db). The JDBC User and Password fields should be set to the same values as you use for username and password when you connect normally. Hope this helps Rob -Original Message- From: Jason Wells [mailto:[EMAIL PROTECTED]] Sent: 27 April 2001 01:09 To: [EMAIL PROTECTED] Subject: [JBoss-user] JDBC Sybase configuration? Hello, I'm trying to get JBoss to use the Sybase JConnect 5.2 JDBC driver for CMP entity beans. I've been looking at the "Using MS SQL Server with JBoss" tutorial on the JBoss site, which is the closest thing I've found in terms of relevant documentation: http://www.jboss.org/documentation/HTML/ch11s17.html And actually, it seems pretty applicable. But there's one area where the instructions aren't too useful, because they vary considerably from driver to driver, and that's the connection pool MBean declaration. I'm thinking it would look something like this... com.sybase.jdbcx.SybDataSource SybasePool ??? user=dbusername; password=dbpassword 4 10 false 120 12 false false true false false 180 1.0 But, I have no idea how to formulate the JDBC URL, or if it's even needed. Also, I wonder if I need "JDBCUser" and "Password" attributes. All of these things seem to vary from driver to driver. Has anyone set this up for the Sybase JDBC driver? Any help is appreciated.
