[JBoss-user] [EJB/JBoss] - home.create () ClassCastException

[shortpasta <nu...@jb...>]

When my jboss 3.2.4RC1 / jvm 1.3.1_02 app is installed on multiprocessor windows machines (2000/xp), I get some really weird behavior.

First of all, my app will run for hours and sometime days.
Then I start getting ClassCastException's thrown by home.create () for stateless session beans.

This is the code in question.  Basically, I am using a cached SiteManagerHome to create a SiteManager stateless session bean remote interface:

  | public static SiteManager getSiteManager () throws Exception {
  |   final HomeFactory homeFactory = (HomeFactory) SingletonManager.getInstance (HomeFactory.class);
  |   final SiteManagerHome home = (SiteManagerHome) homeFactory.getHome (SiteManager.class);
  |   return home.create ();
  | }
  | 

home.create () throws this exception:

  | java.lang.ClassCastException: java.lang.String
  |   at $Proxy72.create(Unknown Source)
  |   at com.syncvoice.vxtracker.util.EjbManager.getSiteManager(EjbManager.java:224)
  | 

It looks as if instead of returning a SiteManager object, home.create () is returning a java.lang.String!

FYI, when this happens, our system is performing a lot of home.create ()'s as it's performing some backend processing.  Note, however, that I do cache the home interfaces (that's what the HomeFactory above does).

I have also seen the same behavior for cmp's, where a cmp home.findByPrimaryKey () should return a cmp local interface, but ends up returning a java.lang.String instead.  As in the above case, the system works fine for hours/days, and then it just starts to happen.

Any help/clues greatly appreciated!
