Loic comes with a hint in the SourceForge bug-report mentionned above, that this may be caused by the new way files are handled in JDK 1.4+. It might not be a problem when running on JVMs prior to this. Haven't had time to check this out yet.

And me also. Real killer bug, shame the error is so generic that people keep getting confused. I can repeat it and have done any number of ways. The paid for jboss doco CMP example even suffer this ailment.

If someone can help I'd be very grateful.

We also experience this problem with the newest
JBoss 3.0.4-Tomcat 4.1.12 and the newest JDK 1.4.1 on Linux.

I re-deploy the EAR file containing a WAR file, and if my
servlet tries to access an EJB using javax.rmi.PortableRemoteObject.narrow, I get a ClassCastException. See attached log.

I thought the redeployment problems have been fixed with 3.0.4.

Cheers, Jörg

THis problem is not specific to 1.4 as suggested in an earlier post. I just used jdk1.3.1 and this problem also exists. Has anyone from the jboss group responded to this post? It seems like it is a rather large bug!

Again,

Remove jndi.properties from deployment or
don't set up an initial context to go over RMI

I have the same problem, but do not go over RMI:

 InitialContext jndi;
 PortalVisitorStatisticsHome portalVisitorStatisticsHome;
 PortalVisitorStatistics portalVisitorStatistics;

 jndi = new InitialContext();

 portalVisitorStatisticsHome = (PortalVisitorStatisticsHome) jndi.lookup("portal-VisitorStatistics");

When I do hot-redeploy console content is:

And then ClassCastException!

I use JBoss 4.0.2
