Test Connectivity fails on JNDI server instance



User is getting a classNotFound exception while performing test connectivity on a JNDI server instance. Observed in Jboss6.4 and Jboss 6.2 application servers.

Error Messages

Required classes are not available, please check the configuration

Error Details:
java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory

Steps to Reproduce

Test Connectivity by using Context factory as org.jnp.interfaces.NamingContextFactory on JNDI-Server.

Root Cause

A software use or operation error 

As per the Jboss application server documents,  one should not use the JNP protocol with JBoss AS7/EAP6.x versions and must change to ejb-client or remote-naming as the JNDI naming implementation.


Perform the following local-change:

Instead of using JNP: "org.jnp.interfaces.NamingContextFactory", use the below remote-naming for JBoss EAP 6.x

Context Factory : "org.jboss.naming.remote.client.initialcontextfactory"
Provider URL : "remote://hostname:portnumber"
