looks like you also need to add the jboss thread pool classes to your classpath

>> C:\jboss\server\default\lib\jnpserver.jar

Does it contain the ThreadPool class? If not, you might have to add some other JARs to classpath as well. Perhaps the others present in the lib folder.

Yes the server could be running but are all those JARs in the class-path?

jnp server and jboss server both should be running;if jboss is running then it is meaningless to run jnp server because jboss internally listen jnpport;

now i am doing is i shutdown the jboss and only jnpserver is running;

now i write above program in jdeveloper to get datasource that is configured in  oracle-ds.xml  .i put jnp-client.jar in jdevloper while running above running;any thing need to be done??

What Is Threat Intelligence?

Threat intelligence is often discussed, but rarely understood. Starting with a precise definition, along with clear business goals, is essential.

Once the JNP server is running, you can configure your application to use JNP by including the jnp-client.jar file in its classpath and specifying the java.naming.provider.url and java.naming.factory.initial properties in either the system properties or the jndi.properties file. the following shows an example jndi.properties file:

 java.naming.provider.url=jnphost.mycompany.com:1099
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming

refer to this to detailed steps to set up stand alone jnp inside your jdeveloper (or other environment):
