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