Hi Krish,

You Can use EJB Model in java Dynpros, Refer to these links you will find all The Process for Developing an application using EJB's.

create an ejb module Project

apply a stateless session bean, implement your business logic and add the methods to interface

right click your ejb project and select Development Component > Show In > Component Properties from context menu

switch to the permissions tab and select Entity forwarding

create a Java EE Enterprise Application Archive (ear) file and reference your ejb

create WebDynpro DC

import your ejb

I Hope This Information might be Helpful for you.

Hi Krish,

In addition to Madhu's suggestion,

As per the Java Bean Model creation steps, you will need to add the Commanad Bean JAR too in your Project, and while creation of Model, you need to select this Command Bean JAR and not the Bean Project JAR.

Hi Krish,

Add ejb20.jar as External jar ( jar file will be there in the server installation folders) in the Java Build Path of webdynpro project.

This will solve your issue.

Thanks
