WarClassLoaderDeployer and WAR redeploy

cdelory Feb 10, 2010 12:21 PM

Hello everybody

I need my WAR to share the same class loader as my MBean present in the JBoss 5.1.0 distribution, and thus I removed the WarClassLoaderDeployer from the war-deployers-jboss-beans.xml, as explained in http://community.jboss.org/wiki/useJBossWebClassLoaderinJBoss5

(if needed, I'll explain in a future post the reason of this "custom" setting, but it's not the point at this very moment.)

The WAR is located in an EAR, which also own sessions beans.

From time to time, I need to "hot" redeploy the EAR.

Redeploy is performed though the appropriate method in MBean "jboss.system:service=MainDeployer".

Then I encounter an error as soon as one of the redeployed classes is needed by my MBean, which is reproduced below.

I can't figure out if it's a bug or a feature...

Help would be much appreciated. Thanks!
