Hi Sivaganesh,

Normally your servlet wil be hosted on apache tomcat server. If such a server were accessible by the SAP system the RFC will be hosted on, then you could create a HTTP request in your RFC enabled FM to call and execute your servlet.

Check out the following SAP Help link that shows you how to excute a HTTP request. You can create new request object host or by HTTP destination in SM59.

Hope that helps you out.

Hi Sivaganesh,

Ah. I misunderstood your requirement.

If you have already created the RFC as a Web Service, then surely it is possible for you to execute the Web Service from your Servlet.

I'm not totally clear on your architecture, but you can call a Web Service from Java by following this tutorial.

Creating a Simple Web Service and Client with JAX-WS - The Java EE 5 Tutorial

If your Servlet is hosted on NW Java..take a look at this

Hi Sivaganesh,

I'm still not totally clear what you are trying to achieve.

Are you trying to create a Web Service from your SAP ABAP NW system based on an existing FM?

Thanks,

Katan
