SOAP request exceptionjava.lang.ClassCastException

I am using EJB3 and hibernate running on jboss4.2.2.GA with jdk1.5

I have several soap web services and when I deploy EAR to the server, once the deployment is done and comes a request to my web services I get the following exception. BTW I can't figure out why but when I test it on local server there is not any error messages, wierd..

Any help would be appreciated, thanks in advance guys.

The problem is most likely that there is a different version of SAAJ in your web appliation. did you include the saaj*.jar files accidentally using the CXF web service facet? Delete them and you should be ok.
