How will you send a SOAP message from the jsp application, do you have the client code to do this? else You could use java client proxies instead to send the message to XI from you jsp application.
1. If JSP page is working in server A and XI in server B then can I call xi server from jsp page by passing xi server credential (username,password,bus service).
2. I have seraching sdn and there it shows soap -- xi --- r/3 scenario.
There is nothing like you cannot use it. Going with your approach, can your jsp application send a SOAP request message to XI? The Java application you are using should be able to make webservice calls(Java client code needs to be written for that in the sender application). Confirm if this is possible, then you can use SOAP approach.

2. For SOAP Approach
Suppose I need to send two parameters from my jsp to xi to R/3 and it will return some result.
What is webservice and how can I use webservice and and how can I invoke that webservice from my jsp page --- so that my request parameters values go to xi and to R/3 and then result from R/3 to xi and to my jsp page. Pls explain.
If the right ports are opened and you do not have firewall issues you should be able to with the right credentials! This is not only for java proxies but even to make webservice calls. System A should be able to access system B in any case.
About webservices, you can generate a WSDL for the outbound message interface that you develop in XI, this WSDL will have to be consumed by the Java application(you will need to do client coding for that). If you need a response back you will have a synchronous interface. There is a document called "How to use the SOAP adapter" in the How to guide section, read that, you will get a better idea.
If you want to know what web services and WSDLs are, go to google and do a search you will get a lot of info.
