        I know very well what is remote debug.

        But I can not debug things i can not see!

         

        I had already debugged my code and in a step by step, everything seem ok.

        And in step by step i can not see where the time is spent!

         

        I had already tried this:

         

        /** <code>select o from TUsers o</code> */

            public List<TUsers> getTUsersFindAll(int firstResult,int maxResults) {

         

                      long start = System.currentTimeMillis();

                      Query query = em.createNamedQuery("TUsers.findAll");

         

         

                      if (firstResult > 0) {

                                                query = query.setFirstResult(firstResult);

                            }

                            if (maxResults > 0) {

                                      query = query.setMaxResults(maxResults);

                            }

         

                            List result = query.getResultList();

         

                            System.out.println(System.currentTimeMillis() - start);

                            return result;

         

            }

         

        system out is zero or 1!

         

        that was the first thing i done to find out where is the problem.

          the configuration file what you sent me have some different configurations...

           

          my conf file have uncommented:

           

          <property name="com.arjuna.ats.jta.recovery.XAResourceRecovery.JBMESSAGING1"

               value="org.jboss.jms.server.recovery.MessagingXAResourceRecovery;java:/DefaultJMSProvider"/>

           

          <property

                      name="com.arjuna.ats.arjuna.recovery.recoveryExtension1" value="com.arjuna.ats.internal.arjuna.recovery.AtomicActionRecoveryModule"/>

          <property

                      name="com.arjuna.ats.arjuna.recovery.recoveryExtension3" value="com.arjuna.ats.internal.jta.recovery.arjunacore.XARecoveryModule"/>

           

           

          should i use yours?

            recoveryExtension1 and recoveryExtension3 should defo be commented.

             

            I dunno where JBMESSAGING1 came from, maybe your own addition? it's not in the default cfg.

              André Simões Newbie

              JBMESSAGING1 comes from EAP. I compared the three files and EAP also have this one.

              I will test the conf file that you send me.

                I tested with the file you sent me, but the results are the same...

                As you understand, i can not spent all my time testing some configuration conbinations what, eventually will work...

                 

                Look at this fragment of code:

                 

                for (int j = 0; j < numbReq; j++) {

                          System.out.println("1 :" + System.currentTimeMillis());

                          List<TUsers> result = userFac.getTUsersFindAll(-1, -1);

                          System.out.println("2 :" + System.currentTimeMillis());

                          if (result == null || result.size()<1)

                                    System.out.println("null result!!!");

                }

                 

                 

                This code runs in a Jboss thead.

                userFac.getTUsersFindAll(-1, -1);

                is:

                 

                userFac -> stateless LOCAL bean

                 

                public List<TUsers> getTUsersFindAll(int firstResult,int maxResults) {

                          System.out.println("1.a :" + System.currentTimeMillis());

                          long start = System.currentTimeMillis();

                          Query query = em.createNamedQuery("TUsers.findAll");

                          System.out.println("1.b :" + System.currentTimeMillis());

                          if (firstResult > 0) {

                                              query = query.setFirstResult(firstResult);

                          }

                          if (maxResults > 0) {

                                    query = query.setMaxResults(maxResults);

                          }

                 

                          List result = query.getResultList();

                 

                          //System.out.println(System.currentTimeMillis() - start);

                          System.out.println("1.c :" + System.currentTimeMillis());

                          return result;

                }

                 

                 

                I will show you the result of all system out:

                lets look to the values!

                First run:

                1 -> 1.a = No delay, ok

                1.a -> 1.b = First time, looks ok

                sql query = ok

                1.b -> 1.c = First time, looks ok

                1.c -> 2 = can't understand!, Not ok

                 

                Second run:

                1 -> 1.a = No delay, ok

                1.a -> 1.b = No delay, ok

                no sql query = ok

                1.b -> 1.c = 2 ms, ok

                1.c -> 2 = ~50 ms, NOT OK

                 

                Third run:

                1 -> 1.a = No delay, ok

                1.a -> 1.b = No delay, ok

                no sql query = ok

                1.b -> 1.c = 2 ms, ok

                1.c -> 2 = ~50 ms, NOT OK

                 

                So, if i do not have this ~50 ms delay, that I do not understand what it is, i should have good performance.

                I do not know what more can i send you to you understand this!

                 

                I do not have any more tools to debug this part of  the ejb return.

                 

                 

                I only see here two results:

                1º I'm doing something wrong

                2º This do not work on JBOSS 510
