That exception says that initializing of the InitialContext has failed for your Client_TestPortal application. The resaon is that it has been unable to load the class org.jnp.interfaces.NamingContextFactory which (I presume) the default Java Naming provider for your platform.

It appears that your apps classpath is missing a required JAR file. According to this findjar query it could be one of the following:

[LOCAL] jbossall-client.jar
[LOCAL] jbossjmx-ant.jar
[MAVEN2] jnpserver-3.2.3.jar
[MAVEN2] jbossall-client-3.2.1.jar
[MAVEN2] jbossall-client-3.2.3.jar
[MAVEN2] jbossjmx-ant-3.2.3.jar
[MAVEN2] jnp-client-3.2.1.jar
[MAVEN2] jnp-client-4.0.2.jar

... or something like that. Which (if any) of the above JARs is most appropriate is hard to say.

You have not provided enough information like the environment you are using, The app server etc.

Any way it lloks like JNDI related JAR is not on the classpath. If it is in place and still not working, then you may have missed to put the correct context information, so pass the JNDI information to the constuctor of InitialContext.

I had the same problem but I found how to fix it. All you have to do is add the jbossall-client.jar library to the clients project, and done!!! You can find the file inside the client folder. e.g jboss-6.1.0.Final_GPT\client I was using Jboss 6.1.0 You can also get help from this link https://community.oracle.com/thread/1157701?start=0

Hope it helps.
