Hi,
Problem
A developer creates an endpoint interface for an existing stateless session bean. Which is the correct mapping approach?
Options
Select 1 correct option.

1. RMI

2. Handlers

3. WSDL-to-Java

4. Java-to-WSDL

correct option is :Java-to-WSDL
Source:www.xyzws.com

Can any explain me why it is so ?
Thnaks in advance.

To serve the purpose of interopability, it's always preferred to create WSDL first and then use WSDL to Java to create Webservice end points.

But, as we have already the EJBs serving the business logic (and ofcourse having Home and Remote interfaces), we can easily create Webservice end point potentially consisting of the methods present in Remote interface using Java to WSDL. In this way, we can convert the existing EJBs to EJB end points so that client can invoke these services by sharing the created WSDL.

Any ideas welcome!

Thanks and Regards,
Naren
