[jboss-user] [EJB/JBoss] - org.jboss.tm.JBossRollbackException

[Guy007]

I have a stateless session bean which accesses an EJB3 entity.  When I use entitymanager.find() it works fine, but when i do persist() i get the following error:


 org.jboss.tm.JBossRollbackException: Unable to commit, tx=TransactionImpl:XidImpl[FormatId=257, GlobalId=jupiter/31, BranchQual=, localId=31] status=STATUS_NO_TRANSACTION; - nested throwable: (javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: Could not execute JDBC batch update)

  | etc etc


the method i am calling is:

 @TransactionAttribute(TransactionAttributeType.REQUIRES_
  |     public String mymethod() {
  |       ...
  |       entitymanager.persist(mybean); 
  |     }


where mybean is as follows:

  anonymous wrote :  
  | public class Mybean implements Serializable {
  | 
  |  @Id
  |     @Column (unique=true, nullable=false, length=32)
  |     private String name;
  |     
  |     public MyBean() {...}
  |  
  |    ..........
  | 



any ideas why! it is driving me insane!


i have been working on it for a week now... no success!
