JBoss: 3.2.3 on WindowsXP / Hibernate: 2.11 / Postgres 7.4
Hi all, sorry my english, I'm braziliam and this text was translated with babelfish :-)
I have an problem with Hibernate using MBean solution provided by 
http://www.hibernate.org/66.html
The problem is:
The ejbA have a business rule thats call 2 sucessive hibernate methods in ejbB, like this (all ejbs are stateless):
Code:
//in ejbA
EjbB ejbB = null;
public void ejbCreate() {
    ejbB = ((EjbBHome) serviceLocator.getService(EjbBHome.JNDI_NAME)).create();
}
public boolean removeActorByID(int id) {
  String hql = "from Actor a where a.id = " + id;
  ejbB.delete("hql");
  if (ejbB.find("hql") == null) {
    return true;
  }
  return false;
}
//in ejbB (This ejb is based on Konstantin Pribluda's Hibernate demo implementation)
 public void delete(String query) {
  try {
   Session session = getSession();
   session.delete(query);
   session.flush();
   session.close();
  } catch (Exception e) {
   ctx.setRollbackOnly();
  }
 }
 public List find(String query) {
  List objs = null;
  try {
   Session session = getSession();
   objs = session.find(query);
   session.close();
  } catch (Exception e) {
    return null;
  }
  return objs;
 }
The error occurs in EjbA when "find" is called after "delete" raise an error (eg Violates FK), calling setRollBackOnly. 
The error is "Could not register synchronization with JTA TransactionManager"
I know that this error not is caused by Hibernate (
http://forum.hibernate.org/viewtopic.ph ... +exception), but how I can resolve it? I need to synchronized these ejbs? How?
