Jaikiran,

It doesn't work.

This is mi relevant code.

EJB3

@Stateful(name = "DiccionarioEJB")
@Remote(value = RemoteEJBService.class)
public class DiccionarioEJB extends AbstractSessionFacade implements
        DiccionarioRemote {

    private static Logger log = Logger.getLogger(DiccionarioEJB.class);

    @Resource(mappedName = "java:/smsds")
    private DataSource dataSource;

    @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
    @TransactionTimeout(500)
    public ResultObtenerDiccionario obtenerDiccionario(AbstractCommand command) {

        testConnection();

        try {

            // sleeps 20 seconds
            Thread.sleep(20000);

            testConnection();

        } catch (Throwable t) {
            System.out.println("SUCCESS! Expected tx timeout error");
            t.printStackTrace();
            return null;
        }

        return null;

    }

    private void testConnection() {
        Connection conn = null;
        try {
            conn = this.dataSource.getConnection();
            System.out.println("Got connection");
        } catch (Throwable t) {
            System.out
                    .println("Error while getting connection from tx aware datasource: ");
            throw new RuntimeException(t);
        } finally {
            if (conn != null) {
                try {
                    conn.close();
                } catch (SQLException e) {
                    System.out.println("Error closing connection "
                            + e.getMessage());
                }
            }
        }
    }

}

JTA timeout set to 10 seconds

<!-- JBoss Transactions JTA -->
   <mbean code="com.arjuna.ats.jbossatx.jta.TransactionManagerService"
      name="jboss:service=TransactionManager">
      <attribute name="TransactionTimeout">10</attribute>
      <attribute name="ObjectStoreDir">${jboss.server.data.dir}/tx-object-store</attribute> 
   </mbean>

Log

15:18:07,252 WARN  [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.BasicAction_58] - Abort of action id 7f000101:a89c:4c9b9942:32 invoked while multiple threads active within it.

In my example the global transaction time out was set to 10 seconds, my EJB method is annotated with 500 seconds, the EJB method first testConnection, then sleeps 20 seconds and finally tries to connect again but it fails because the transaccion is not active anymore.

What is wrong?

Thanks.
