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 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:

    
        com.example:archive=unique-archive-name
        java2ParentDelegation=false
    

...

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