Exception in JMSCI message listener

[nicdo77]

Hi there,
I'm having a big problem with JMS queues.
OK here is the context.
Until this morning, i had an application running perfectly on JBoss3.2.3, under Java 4, with no webservices and JMS queue.
I updated it on my production environment, adding a WebService feature to connect onto a distant WebService.
I added the following librairies:
- axis-1.4.jar
- axis-jaxrpc-1.4.ar
- axis-saaj-1.4.jar
- axis-wsdl4j-1.5.1.jar
- commons-discovery-0.2.jar

When i restarted my JBoss server, the new feature was working perfectly and doing what i was expecting (connecting and sending datas over the network to a distant server). BUT, on the other side, everytime a message was being sent to or from my JMS queues, i was having this error message:

12:44:10,810 ERROR [JMSContainerInvoker] Exception in JMSCI message listener

I'm really worried about this cause i really need to make it work. And if the JMs queues does not work anymore, i lose all the interest of my app.

Hope you will be able to help me.

Let me just explain briefly the context of my project. This application is communicating with another app via the WebService i'm talking about. My colleague is developing the other app and generated for me the client code to connect to the WebService, since he is hosting the WS. I don't know anything about WS, and he doesn't know anything about the app i'm developing, so i'm queit obliged to use Axis and he can't really help me.
Thats why i hope there is an easy answer/solution to my problem, cause i'm not able to do anything with WebService.
I know, i could try, but the point is, i just arrived on this app, and they NEVER put any test environment. So to try things out, i'm obliged to try them directly in production environment. So i don't really want to try new solutions (and creating a whole testing environment would oblige me to handle JMS queues, and my app is really to complex for this i guess... besides the messages received on JMS queues are sent by a distant module that i can't really simulate)
Anyway, hope you will be able to help me...

Just realized my problem could come from an API conflict.
I checked my code of com.thalys.localys.frontal.MessageTrainCreator.marshall, and inside i use jaxb-api.jar...
And one of the librairies i added was axis-jaxrpc-1.4. Could this be a problem and create my exception???

Thank you in advance.

[nicdo77]

So, no one has any clue?
Tell me if you didn't understand anything... :)

[nicdo77]

Pleease?

What is so difficult to undertand about this:

java.lang.NullPointerException
 at com.thalys.localys.frontal.MessageTrainCreator.marshall(Unknown Source)

It's a bug in your code.

[nicdo77]

Hey Adrian,

Sorry, yes i know the error is not exactly in my code.

But maybe you can still help me,
I checked my code of com.thalys.localys.frontal.MessageTrainCreator.marshall , and inside i use jaxb-api.jar ...
And one of the librairies i added in JBoss libs was axis-jaxrpc-1.4 . Could this be a problem and create my exception??? Could there be a library conflict.

Thank you in advance.
I guess this forum is not the place to solve my pb anymore, but we never know...

It's not JBoss code either.

Which isn't shipped with JBoss-3.2.3
http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/tags/JBoss_3_2_3/thirdparty/sun/
it is part of JDK6 but that's irrelevant to you if you are on JDK1.4

You want me to guess, without seeing the code and a single stacktrace
that shows an NPE? :-)

JBoss-3.2.3 included an older version of axis.
http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/tags/JBoss_3_2_3/thirdparty/apache/axis/
(3.2.3 is nearly 4 years old)

It is 1.0-RC1 according to this:
http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/tags/JBoss_3_2_3/thirdparty/apache/axis/release-notes.html?revision=54874&view=markup

But any problems with Apache Axis aren't an issue for a JBoss JMS forum.
The only (very tentative) relationship is that you're using Axis from an MDB
in the business method.

[nicdo77]

OK thanks for the reply, i will try with the few links you gave me and find the correct forum to solve my problem. I guess your links will help me anyway.

Thank you very much.

And is this wrong?

[adrian.brock]

It is if the static initialization threw a JAXBException, jc will be null.
But that's not a JMS question either.
