Hi,

You should add com.sap.engine.services.jndi.InitialContextFactoryImpl class in your client classpath.

(this class you can find in the sapj2eeclient.jar)

<b>Hi Andrei</b>

<b>I had already added this jar. Once i rebuild my project it get removed from the build path and gives the same error again.

If without building i just run the project after adding this jar , it gives the following error:</b>

javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

Hi,

It means that you should add next lines in your code when you create initial context:

Hashtable prop = new Hashtable();

prop.put("java.naming.factory.initial", "com.sap.engine.services.jndi.InitialContextFactoryImpl");

InitialContext context = new InitialContext(prop);

Hi frndz

Finally Ejb Lookup is completed successfully .

Thankyou verymuch. The problem was with the corrupted jar ,due to which the java client was throwing error.
