Hello Peter, Yes, I am aware of that MySQL 5 issue. I already fixed that. Hummm....I can try to delete the tables I created on the database and do another build and see if Hibernate then creates the tables for me... I found a setup.dll and created the tables. Then my error changes to this one: | 14:47:29,569 ERROR [JDBCExceptionReporter] Cannot add or update a child row: a foreign key constraint fails (`geportaldb/jbp_forums_topics`, CONSTRAINT `FK6C1A04CAC1FFF134` FOREIGN KEY (`jbp_poster`) REFERENCES `jbp_forums_users` (`jbp_id`)) | 14:47:29,584 ERROR [ForumsModuleImpl] Cannot create topic | org.hibernate.exception.ConstraintViolationException: could not insert: [org.jboss.portlet.forums.impl.TopicImpl] | at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:71) | at org.hibernate.exception.JDBCExceptionHelper.convert | ... | I Have a feeling, I did something wrong... thanks Mariella.
