JaxWS ClassCastException on JBoss

Question

I\'m using JBoss 5.1.0.GA (for JDK6), and jaxws 2.2.6. When I invoke the webservice, I get the following exception:

java.util.ServiceConfigurationError: j

Answer 1

I faced the same issue. I am running JBoss 5.1 EAP along with JDK 1.6_22.

I did things slightly different. I combined the solution by Carlo plus this solution.

I created an endorsed folder under $JBOSS_HOME/server//lib/endorsed. I then copied over streambuffer.jar, stax-ex.jar, policy.jar, jaxws-rt.jar, jaxws-api.jar, jaxb-impl.jar, jaxb-api.jar and gmbal-api-only.jar.

I left the $JBOSS_HOME/lib/endorsed alone.

Doing this, I was able to get it to work it all to work

Answer 2

I had the same problem on JBoss 5.1 EAP Instead of putting jar files into JBOSS application server it is more robust when you alter class loading logic by isolating WAR with Overriding Server Classes (http://www.jboss.org/community/wiki/classloadingconfiguration) In my case I have 3 environments. With this solution I can move war file from one JBOSS instance to another and it will still work.

I resolved this problem by: Adding this to jboss-web.xml:

<class-loading java2ClassLoadingCompliance="false">
    <loader-repository>
        com.example:archive=unique-archive-name
        <loader-repository-config>java2ParentDelegation=false</loader-repository-config>
    </loader-repository>
</class-loading>

...

and by adding requierd jars into war (jaxb-api.jar, jaxb-impl.jar, jaxws-api.jar, jaxws-rt.jar)

Answer 3

Finally, I've managed to solve my problem: I put jaxws-rt.jar in $JBOSS_HOME/lib/endorsed.

EDIT
I had the same problem on JBoss 5.1 EAP, and to solve it, the steps are a little different: in $JBOSS_HOME/lib/endorsed I removed the old jaxb-api.jar, then copied

• jaxb-api.jar
• jaxb-impl.jar
• jaxws-api.jar
• jaxws-rt.jar

from the latest jaxws-ri package, and eventually it worked.
