Hi,

In any B2B scenario, you're going to have stricter security requirements. XI and other SAP applications in the vast majority of cases reside within the internal network of a company, as I'm sure it does for your company A. It is recommended to have some kind of reverse proxy/web switch hardware/software residing in the DMZ to intercept the external request. Direct requests (especially HTTP) by most, if not all, companies will not be allowed to freely pass to applications within a company's intranet.

SAP has something called the Web Dispatcher that is commonly used for such a purpose. You can find more info on it at the following link:

You'll also find some visuals and more security related topics at the following link:

In addition, you'll probably require a more secure transport protocol like HTTPS/SSL as well.

To call any web service you would need the corresponding the WSDL for it. Once you import this WSDL in your JAVA IDE< it would genrate the necessary objects required for the call. The java API should have means to pass the user id and password. You can search this at any java forums.
