I have a java plugin node that makes a call to an EJB method. The bean is deployed on WAS 5.0
An exception is raised when I try to retrieve the initial context.
b4 context
exe Cannot instantiate class: com.ibm.websphere.naming.WsnInitialContextFactory
Broker is on z/OS , WMQI 2.1.
I have faced this issue with HP UX too. Has anyone got this working ?

Do you get this error at deploy time or at runtime?
Are there more errors logged into system error log? Is your classpath set correctly?

I get this error at runtime, when i put a message and the evaluate method is executed.
This is my code in evaluate
public void evaluate(MbMessageAssembly assembly, MbInputTerminal in)
throws MbException
{
System.out.println("Start Of Evaluate");
try {
File elogFile = new File ("/tmp/mfplugin.log");
PrintStream elog = new PrintStream (new FileOutputStream (elogFile), true);
System.setOut (elog);
MbMessage glb_env = assembly.getGlobalEnvironment();
System.out.println("After MnMessage");
MbElement mbElem_env = glb_env.getRootElement();
System.out.println("After MbElement");
String name = (String)((mbElem_env.getLastChild()).getName());
System.out.println("Element Name " + name);
MbElement mbElem_env1 =
mbElem_env.getFirstElementByPath("/Variables/MyVar");
String val = (String)mbElem_env1.getValue();
System.out.println("Element Val " + val);
System.out.println("Test the new jar " );
Hashtable env = new Hashtable();
env.put( Context.INITIAL_CONTEXT_FACTORY,INITIAL_CONTEXT_FACTORY );
env.put( Context.PROVIDER_URL, "iiop://10.100.81.3:2809");
System.out.println("b4 context");
Context cxt = new InitialContext( env );
System.out.println("after context");
System.out.println("before lookup");
Object obj = cxt.lookup("cell/nodes/test/HelloWorldHome");
System.out.println("af lookup");
System.out.println("The Class Name is");
System.out.println(obj.getClass().getName());
HelloWorldHome home =
(HelloWorldHome) PortableRemoteObject.narrow(
obj,
HelloWorldHome.class);
System.out.println("To create remote : " );
HelloWorld bean = home.create();
System.out.println("Invoking Bean Function");
System.out.println(bean.hello(val));
System.out.println("After a call to Bean Function");
}catch( Exception exe ){
System.out.println("exe " + exe.getMessage());
exe.printStackTrace();
}

| I would suggest you get the ejb call working as a standalone client first, before implementing as a plugin. |

Well, in that case you've probably got jar's missing from the jplugin directory that contain the JNDI provider.
Check the classpath for your standalone program, and make sure everything is present in the jplugin directory. |

Tried it on Windows Broker , I used the 'interact with desktop option to see the system messages' it hangs after printing b4 context.
Why do u say the 'jplugin ' directory? I have only the java node jar in the jplugin folder and the rest are in the classes folder where wmqi system jars are present.Does'nt it load from there?
