RFC wd java

Hi

I have an requirement to create a WD java application that will take a user id as input and make a RFC call to the backend to retrieve the infotypes assigned to the users.

This application will then pass the information retrieve onto a JSP page which will render a HTML page dynamically based on the information we get from the RFC
.

Question is, how can I pass the information onto the JSP page? and I am not familiar with RFC coding, what exactly is involved in terms of the RFC in relation to the requirement above?

Thanks

Adnan
