[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - No Class Loader error during deploy

[arupsarkar]

Hi:

JBoss version 4.0.2
Jdk 1.4.2
MySql 5.0
Myeclipse ide

I have created a Hibernate capable project. I am using a service locator to identify the Hibernate Session Factory and Session using JNDI. I have created a hibernate.cfg.xml. I am also using hibernate doclet to generate jboss-service.xml, but I am getting the following error during deployment.

"org.jboss.deployment.DeploymentException: No ClassLoaders found for: net.sf.hibernate.jmx.HibernateService; - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: net.sf.hibernate.jmx.HibernateService)"

Any help would be highly appreciated.

Regards
Arup
