Some Kid [https://community.jboss.org/people/sam-user] created the discussion "Hibernate 3.3.1 problems under JB 7" To view the discussion, visit: https://community.jboss.org/message/737396#737396 -------------------------------------------------------------- I'm working on the migration of a Seam 2.1.1/Hibernate 3.3.1 application from JB5.1 to JB7 and the main problems I have are related to Hibernate and the incompatibility between it's versions (prior and after 3.5) I managed to deploy my application using the provided Hibernate module (ver.4.0.1) and for the most of the time it works fine. Until I try to save an entity in the DB. I have entities that have String ID columns and I get exception "Unknown integral data type for ids : java.lang.String" when an Id is generated via SequenceGenerator. I know this is a Hibernate issue but if anyone has any solutions for this -please share your experience. I also tried using the original version of Hibernate (3.3.1) following the advices in the guide "How do I migrate my application from AS5/As6 to AS7". And I stumbled across a different problem: I get the exceptions below: 14:40:12,063 DEBUG [org.jboss.as.jpa] (MSC service thread 1-4) added (default provider) org.hibernate dependency to XXX.war
