Hi guys i have a very strange problem with jboss and lieferay. I use the jboss7.1 and liferay 6.2.

If I deploy my own ear project and access my ejbs via remote or locale interface everything is fine.

But if i now dodeploy the liferay root war, i get an

java.lang.ClassCastException: Entity_$$_jvst1c4_ae cannot be cast to org.hibernate.proxy.HibernateProxy

exception.

My ear Projekt uses the following jboss-deployment-structure.xml:

<deployment>

        <exclusions>

            <module name="deployment.root.war" />

        </exclusions>

        <dependencies>

            <module name="org.hibernate" export="true"/>

            <module name="org.jboss.common-core" export="true" />

            <module name="org.apache.velocity" export="true" />

            <module name="javax.faces.api" export="true" />

            <module name="org.apache.commons.io" export="true"/>

        </dependencies>

    </deployment>

I exclude the liferay war explicit but think is not necessary and it changes nothing. I not other dependencies to these liferay root war.

I think it could be a problem of liferay classloading? In the root.war i have found a hibernate3.jar but my ear and jboss uses hibernate4.

The javassist.jar is the same in liferay and jboss (3.15GA).

I dont understand whats going wrong. No Idea how an additional deployes war could influence my ear, i thought they are isolated by default.

Any Ideas or similar behaviour? Need help, thanks a lot.
