classloader disabled?

Hi,
 
I am using ehCache replication which uses RMI to communicate among peers. My app is hosted by tomcat 6. When the ehCache manager tried to replicate an object it throws an exception as below. It is obvious enough so I added my own security policy for all my deployed jar files to the tomcat JVM, and give them all security permission (for testing), but still get the exception. Your help of pointers would be much appreciated.
