[jboss-user] [JBoss Cache: Core Edition] - Replication, CacheMarshaller, Region

[ekobir]

Hi All

As I would like to store some custom  externalizable classes in the cache, i created  region on the cache. But it didnt help me not to get ClassNotFoundException.

Scenario exactly as explained in faq.

 I'm using JBoss EAP 5.0.0 (Only supported version available). It uses jbosscache 3.0,3GA.  My jboss-beans.xml file under META-INF of ear file. So when class is loaded, 
cache will be created on that server.

My Question is

What is the best way for handling class loader problem? 
Do I need to write a Marshaller from scratch or is there any delegation available for application to provide class loader?



please find cache configuration below.
