    setEntityContext not being called

    Darran Lofthouse Master

      Hi,

      I am using JBoss 3.2.1 with Suns JDK '1.4.1_03'.

      I am experiencing a problem where the method setEntityContext is not always being called correctly.

      In my test case I have a simple CMP entity bean with two properties and a session bean to access the entity bean.

      I first run a client to call 'initialise' on the session bean, this creates three different instances of the entity bean and the following messages are displayed :-

      10:55:26,702 INFO [STDOUT] setEntityContext
      10:55:26,712 INFO [STDOUT] setEntityContext
      10:55:26,712 INFO [STDOUT] setEntityContext


      I then run a different client to call testBeans on the session bean and the following messages are displayed :-

      10:55:33,783 INFO [STDOUT] setEntityContext
      10:55:33,793 INFO [STDOUT] Bean Fount = 'Test 2', Test Bean 2
      10:55:33,793 INFO [STDOUT] This instance is 'Test 2'
      10:55:33,793 INFO [STDOUT] The local interface is for 'Test 2,


      I then wait for 15 minuted and run the client that calls testBeans again, this time the following messages are displayed :-

      11:11:37,498 INFO [STDOUT] Bean Fount = 'Test 2', Test Bean 2
      11:11:37,498 INFO [STDOUT] This instance is 'Test 2'
      11:11:37,498 INFO [STDOUT] The local interface is for 'Test 3,


      This time setEntityContext is not called so when I try and obtain the local interface to the bean I end up with the local interface to a different bean.

      Has anyone else experienced anything similar to this?

      For some reason the attach files button does not appear to be working so I have pasted the beans below :-
