Hi, If you want to load your Entities (with or without Seam component) from a seperate JAR then you should register those entities in your persistence.xml file like this: | <persistence-unit name="4cWebDatabase" transaction-type="RESOURCE_LOCAL"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <class>com.fpc.carconfig.frontoffice.entity.Allocation</class> | <class>com.fpc.carconfig.frontoffice.entity.LoginData</class> | <class>com.fpc.carconfig.frontoffice.entity.EndUser</class> | <class>com.fpc.carconfig.frontoffice.entity.TestClass</class> | <class>com.fpc.carconfig.frontoffice.entity.UserData</class> | <class>com.fpc.carconfig.frontoffice.entity.Offer</class> | <properties> | <property name="hibernate.hbm2ddl.auto" value="update"/> | <property name="hibernate.show_sql" value="true"/> | <property name="hibernate.cache.provider_class" value="org.hibernate.cache.HashtableCacheProvider"/> | <property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect"/> | | | </properties> | </persistence-unit> | Hope this helps. http://techieexchange.wordpress.com View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4122096#...
