Hi,

I am getting 'security exception' in server.log on starting jboss ewp 5.1 server. This is preventing few of our modules to startup.

ava.lang.SecurityException: class "org.apache.commons.logging.impl.Log4JLogger"'s signer information does not match signer information of other classes in the same package

These are first few lines of exception. Has anyone faced such exception, please respond and suggest the solution, which was implemented.
