Scheduler and ClassCastException
bloid Jun 9, 2003 4:52 AMHi there jboss experts :-)
I have a problem... I have a scheduler task, which runs every hour, to import some data into an auxilliary database. This Scheduler task has to get a reference to one of my EJBs. This works fine the first time I run it, but if I redeploy my EJB jar, I keep getting the following exception:
2003-06-06 16:27:30,055 ERROR [STDERR] java.lang.ClassCastException

No matter what I try to do to get the proper class;
ImageHome.class ;
Class.forName( "ImageHome" ) ;
Class.forName( "ImageHome" ).newInstance().getClass() ;
I still get the ClassCastException until I restart JBoss, then it all seems to work properly again... It's as if the classpath is getting "stuck" with the old version of ImageHome... But then again, even if I don't change the Image EJB, and just redeploy I still get the same problem :-(
Hope someone can help me :-)
Thanks!
