Hi all,

Why does method org.hibernate.jca.JCASessionImpl.beginTransaction() throw UnsupportedOperationException? Isn´t possible begin a transaction inside a connector?

Follow the implementation of this method:

Code:

package org.hibernate.jca;

public  class JCASessionImpl implements org.hibernate.classic.Session {

....
   public Transaction beginTransaction() throws HibernateException {
      throw new UnsupportedOperationException();
   }
....

}

Rgdes,

Leandro

This code is currently undergoing major refactoring.

However, not allowing Session.beginTransaction() calls basically means that the resource adapter does not support non-coordinated transactions; the TransactionManager must coordinate all transactions against the resource. This is totally reasonable in a J2EE-compliant app server.
