Datasource Lookup from WSAD using POJO - CastException looking up DB2 Data

Question

I try to look up datasource from WSAD test server using stand alone POJO.
Code is like:
Hashtable properties = new Hashtable();
properties.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
properties.put(Context.PROVIDER_URL, serviceURL);
properties.put(Context.PROVIDER_URL, "iiop://localhost:2813");
Context context = new InitialContext(properties);
ds = (DataSource) context.lookup("jdbc/myDS");
Context and datasource are set properly.
I get exception below when I look up datasource:
Exception in thread "P=646891 =0:CT" java.lang.ClassCastException: javax.naming.Reference
I think additional jar files are needed in class path.
What additional jar files do I need in build path to look up datasource?
I am using DB2. Datasource is properly configured in WSAD test server.

Refer to this article.

It provides all the information you need to perform a JNDI lookup. Quoting from the artice;
To execute our external Java application, make sure your environment is prepared and use a Java command of the following form to invoke the client application:
%JAVA_HOME%/bin/java -Xbootclasspath/p:%WAS_BOOTCLASSPATH%
-classpath <list of the referenced jars, classes, and resource directories>
-Djava.ext.dirs=%WAS_EXT_DIRS%
-Djava.naming.provider.url=iiop://<server:orb port>
-Djava.naming.factory.initial=com.ibm.websphere.naming.WsnInitialContextFactory
%SERVER_ROOT% %CLIENTSAS% <fully qualified main class of the application client>;
