Any program can be called from a Rich UI program. The best way is to wrap the program in an EGL library function and expose it as a service (either SOAP or REST, although REST is my preference). Then in your Rich UI you just define the service using an interface and invoke it using a @RESTBinding. All-in-all, maybe 10 lines of code.

There are some caveats to calling service programs vs. standard bound ILE programs, primarily due to the limitations of the JT400 service program call class, which in turn is limited by the i5/OS generic call interface. You can only have seven parameters, and the return from the called procedure can only be an integer. But as long as you design your interfaces to use a few data structures rather then dozens of individual parameters, you're good to go.
