Hi Michael,
thanks for pointing to the rights JARs for the persistance-package. I was able to solve that conflict by putting the javax.persistance.* (so the geronimo-jpa_2.0_spec-1.1.jar) in the Tomcat-lib and all the other JARs including openJPA Jar itself in the webapps-WEB-INF/lib. However I am still wonder if there is an advice on this? We have scenarios from users and customers that would like to run multiple instances of openmeetings in the same tomcat servlet container. Maybe somebody has some advice on that? Also we face a *slight* problem with the Relations that openJPA is not able to load after it is updated on its relations. Example Relation Users.java<http://code.google.com/p/openmeetings/source/browse/branches/dev/injection/src/app/org/openmeetings/app/persistence/beans/user/Users.java><=> Organisation_User.java<http://code.google.com/p/openmeetings/source/browse/branches/dev/injection/src/app/org/openmeetings/app/persistence/beans/domain/Organisation_Users.java><=> Organisation.java<http://code.google.com/p/openmeetings/source/browse/branches/dev/injection/src/app/org/openmeetings/app/persistence/beans/domain/Organisation_Users.java> so the User Object has an attribute<http://code.google.com/p/openmeetings/source/browse/branches/dev/injection/src/app/org/openmeetings/app/persistence/beans/user/Users.java#84> : @OneToMany(fetch = FetchType.EAGER) @JoinColumn(name = "user_id", insertable = true, updatable = true) private List<Organisation_Users> organisation_users; We need this extra object Organization_Users cause we have an attribute *isModerator* in each Organization_Users-Object to mark special Users with Moderator privileges for certain Orgs. We update/add Users and Organization_Users INDEPENTLY. Meaning: we have a Java Method: addUser => Persists the Users-Object and we have Java Method: addUserToOrganization => Persists the Organization_Users-Object If we invoke addUser + addUserToOrganization => the User has afterwards NO organisation_users set, no matter if we do: session.refresh(user) or session.flush() or whatever.
