[jboss-user] JBoss AS Issues with hibernate on JBOSS AS 5.1.0

Hello, am note sure this is the correct mailing list for this, feel free to redirect me to correct mailing list if not. I tried to migrate a tomcat (.war) application to JBoss. Unfortunately, jboss has it's own hibernate libraries that it exposes to my webapps, leading to all sort of nasty effects. I managed to get rid of most by removing my own hibernate libraries from the WEB-INF/lib. However, the jboss integrated libraries show this curious message blocking my webapp from starting: org.hibernate.MappingException: Cannot cache an unknown collection: org.tonguetied.keywordmanagement.Keyword.translations I have no idea where it comes from or how to get rid of it. Can not reproduce outside JBOSS. My question are: - if possible, how to get rid of it. - Otherwise, how to have JBoss not expose hibernate librairies to my webapp so my webapp can use it's own. Second option is best to me, as it will prevent future version conflicts between different apps. Help greatly appreciated, am clueless on this.
