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:

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() {...}
|
| ..........
