Answer 1

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.
