Hi All:
My apologies, my previous post was a reply on another subject mixing up the thread. So once more my post but now really as a new thread... I have an ear which contains a war file. The jar files required by my application are in the lib directory of the ear. The WEB-INF/lib directory is empty. I am using hibernate version 3.6.0.Final and I want my application to use the jpa 2.0 of hibernate (hibernate-jpa-2.0-api), so I have added a hidden-classes element with a filter on javax.persistence. However when I have this construction, hibernate doesn't recognize my annotated classes anymore (it gives an mapping exception Unknown Entity). But when I move the libraries from the ear lib directory to the WEB-INF/lib directory I no longer have this exception. I am running on Geronimo 2.2.1 and my deployment plan is: <?xml version="1.0" encoding="utf-8"?> <application application-name="Sample" xmlns="http://geronimo.apache.org/xml/ns/j2ee/application-2.0" xmlns:app="http://geronimo.apache.org/xml/ns/j2ee/application-2.0" xmlns:sec="http://geronimo.apache.org/xml/ns/security-2.0" xmlns:sys="http://geronimo.apache.org/xml/ns/deployment-1.2"> <sys:environment> <sys:moduleId> <sys:groupId>com.sample</sys:groupId> <sys:artifactId>sample</sys:artifactId> <sys:version>0.1-SNAPSHOT</sys:version> <sys:type>car</sys:type> </sys:moduleId> <sys:hidden-classes> <filter>javax.persistence</filter> </sys:hidden-classes> </sys:environment> </application> Am I doing something incorrect in my setup or deployment plan or should this construction work ? Best regards, Marco
