WebFacing input/output parameters

Hello!

I want to use webfacing to build a web-interface on our existing
RPG-application. The application is a 'modular' RPG/400-application, which
consists of many small programs calling each other (OPM, no ILE). We have
tried to build reusable components (small programs), so the possibility to
create multiple entry points within a WebFaced Applicaton is of great value.
One of the components is small program, containing a subfile-window. It
displays our customers, and gives the opportunity to select a customer. The
program 'returns' the customer number to the calling RPG. We call the
program with an 'empty' parameter in its PLIST, and the calling RPG-program
receives the selected customer number.

We woud like to re-use this webfaced program in a Java application. Is it
possible to get the (input) parameter back (output) from a webfaced
application? You can define one or more input-parameters, but if the value
of the parameter is changed can I get it back in the 'calling program'?

Thanks for thinkin with me,
