Hi Guru,

For "HelloStatelessBean" bean code looks like

final Properties _param = new Properties();

_param.put(Context.INITIAL_CONTEXT_FACTORY, "com.sap.engine.services.jndi.InitialContextFactoryImpl");
_param.put(Context.PROVIDER_URL, "<HOST_NAME>:<MESSAGE_PORT(For my case - 50204)>");
_param.put(Context.SECURITY_PRINCIPAL, "<USER_NAME>");
_param.put(Context.SECURITY_CREDENTIALS, "<USER_PASSWORD>");

final Context initialContext = new InitialContext(_param);

final Object obj = initialContext.lookup("sap.com/Hello/Stateless/HelloStatelessBean");
final HelloHome helloHome = (HelloHome)PortableRemoteObject.narrow(obj, HelloHome.class);
final Hello hello = helloHome.create();

System.out.print(hello.getMessage());

Hi Guruvulu,

You can use the EJBs as similar to any other app server in SAP webAS as well.

Please refer to the following two links, if you are familiar a bit with J2EE and EJB then you will certainly be able to solve your problem with them,

Hope that helps,

Guru.

P.S. : by the way i am also called guru
