      I´m having problems to commit a JTA transaction that takes a long time to accomplish. I am executing a stored procedure that takes about 2 hours to execute and when I try to commit my transaction the following exception is throwed:

      Debugging the application (including Seam sources) I found that the exception cames from:




      Synchronizations synchronizations = getSynchronizations();
synchronizations.beforeTransactionCommit();



      I observed that this error only occurs when the time to execute is longer than the EJB idleTimeoutSeconds (see JBoss configuration ejb3-interceptors-aop.xml). So i assume that the EJB that represents the component org.jboss.seam.transaction.synchronizations is removed during this execution and is no more available on the commit time.


      I don´t want to increase the idleTimeoutSeconds and I cant use @CacheConfig to increase only to this EJB since its a internal Seam EJB.


      Is there a solution to this problem? Or some workaround?


      I am using: Seam 2.2.0.GA on JBossAS 5.1


      Some information:


      In my components.xml:


      <transaction:ejb-transaction />



      The EJB from where the SP is called:


      @Stateful
@Local(IOperacaoAction.class)
@Name("OperacaoAction")
@TransactionAttribute(TransactionAttributeType.REQUIRED)
@TransactionManagement(TransactionManagementType.BEAN)
@Scope(ScopeType.CONVERSATION)
public class OperacaoAction (...)



      The way I get my transaction:


      org.jboss.seam.Transaction.instance()
