title: EJB transaction rolled back exception
body: <p>I am using ejb-2
  I get the following exception. Can someone tell me what does it mean, and what can be the possible solution for this:</p>
  
  <blockquote>
    <p>Error (fatal): EJB Exception: ; nested exception is:<br>
                javax.ejb.TransactionRolledbackLocalException: Error committing transaction:; nested exception is:<br>
                weblogic.transaction.internal.AppSetRollbackOnlyException</p>
