[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - java.lang.NoClassDefFoundError with hibernate

[mohammad.gh]

HI

I have and EAR file that contains a WAR file.
In the web-inf/lib of the war file there is a   hibernate-annotations.jar and this file is also included in jboss_home\server\default\lib.
this web project works fine when i run without seam, but after adding Seam to this project i get this error :

com.google.gwt.user.server.rpc.UnexpectedException: Service method 'public abstract ir.itorbit.epic.cartable.api.model.CartablePage ir.itorbit.epic.cartable.client.rpc.process.ProcessService.getProcesses(java.lang.String,boolean,int,int)' threw an unexpected exception: java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.cfg.AnnotationConfiguration

org.hibernate.cfg.AnnotationConfiguration is located in jboss_home/server/default/lib/hibernate-annotations.jar  and web-inf/lib/hibernate-annotations.jar.

i have a jboss-web.xml that contains this line two :
            <loader-repository-config>java2ParentDelegation=false</loader-repository-config>

what is the problem?

the file exist everywhere why this NoClassDefFoundError?
thanks
