deployment fails with classcastexception

[navjeetc]

I am trying to deploying an application which works fine on IPlanet 6.0 and jdk 1.2 to Jboss 2.4.6 on Linux and I get the following error when I copy the ear file to deploy directory:

DeploymentInfo failed:file:/home/navjeet/download/JBoss-2.4.6_Tomcat-4.0.3/jboss/deploy/pc.ear
org.jboss.deployment.J2eeDeploymentException: Error while starting pc.ear: null, Cause: java.lang.ExceptionInInitializerError

Caused by: java.lang.ClassCastException: com.mypc.logging.Logger
at com.mypc.logging.Logger.getLogger(Logger.java:122)

... 32 more

and line 122 in Logger.java is:

return (com.putnaminv.pc.logging.Logger)Category.getInstance(name, factory);

The lst line should read:
eturn (com.mypc.logging.Logger)Category.getInstance(name, factory);

The problem was resolved by renaming Logger class and also changing all references (painful process) to it.

Probably you have the Logger class in the Classpath twice?
Have you deployed it separately to your .ear ?

I've seen this when you've tried lots of things to get it working and haven't cleaned up properly. Try installing on a
clean JBoss install
