    BMP transaction prob in Jboss 3.0.0beta2

    Mac Rinehart Newbie

      I'm having a problem with transactions and BMP entity beans. I just got the build today, and ran clean before rebuilding.

      In my source I invoke a find, which works. I think try to get fields of the entity bean through the remote interface. With trace turned on, I can see that the finder is invoked, then the ejbLoad is invoked when I get the first field. After that my client program receives a Server Exception: RemoteException occured in server thread; Nested exception is java.lang.IllegalStateException: Removing bean lock and it has TX Set!

      Unfortunately I don't have the server stack trace, as the server does not display a stack trace for this exception, even with the DEBUG threshold set. For what it's worth, I've attached the client code that generates the exception. The error line is marked with a *.

      public void testBeanManagedPersistence() {
      &nbsp&nbsp System.out.println();
      &nbsp&nbsp System.out.println("This tester verifies that BMP is working properly.");
      &nbsp&nbsp System.out.println("Creating Harriet Hightower.");
      &nbsp&nbsp AccountHolderBMPRemote harriet = null;
      &nbsp&nbsp&nbsp&nbsp try{
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp Object obj = ctx.lookup("atm/bmp/ejb/accountHolderEJB");
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp AccountHolderBMPRemoteHome bmpHome = (AccountHolderBMPRemoteHome)
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp PortableRemoteObject.narrow(obj, AccountHolderBMPRemoteHome.class);
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp try{
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp harriet = bmpHome.findByIdentity("hhightower", "123");
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp System.out.println("Harriet Hightower is found.");
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp }
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp catch(FinderException e){
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp harriet = bmpHome.create("Harriet", "Hightower", "your.name@your.domain", "hhightower", "123");
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp System.out.println("Harriet Hightower is created.");
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp }
      *&nbsp&nbsp&nbsp&nbsp&nbsp System.out.println( harriet.getFirstName() + " " + harriet.getLastName() + " " + harriet.getEmailAddress());
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp System.out.println("Harriet's Primary key is " + harriet.getPrimaryKey().toString());
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp harriet.remove();
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp System.out.println("Harriet has been removed.");
      &nbsp&nbsp&nbsp&nbsp }
      &nbsp&nbsp&nbsp&nbsp catch(Exception e){
      &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp e.printStackTrace();
      &nbsp&nbsp&nbsp&nbsp }

      This code blows when attempting to invoke harriet.getFirstName(). I can't see that there's a problem with this source. Hopefully someone can offer some insight into what might cause that transaction problem. Thanks,

          The sequence of calls looks very similar to the sequence in the cts/BMPUnitTestCase/tesEjbCreate in the testsuite, which passes for me. Would you consider sending me your bean + junit test to look at and possibly add to the test suite? Could you also check that the test I mentioned passes for you as well?

            I'll do that here. In the mean time, I've been snooping around. That error message I get is comming from the org.jboss.ejb.plugins.lock.QueuedPessimisticEJBLock.removeRef() method. I did a search for uses on that method, that class, and subclasses, and I can't find any anywhere. I know it must be invoked somewhere, otherwise, how could that exception method be generated?


            Ok, I'll run that test and get back to you.

              Ok - I've got your testcase run. I got ten tests passed and one failure. The one that didn't work was testProbeContainerCallbacks. The stacktrace follows:

                FYI - I did a clean checkout and rebuild, and now everything in the BmpUnitTestCase passes.
