VM, assembler and SOCKETS

[Steve Gentry]

Hello. I'm trying to determine if it is possible to call/invoke a Webservice from a program running on VM.
We would like to write it in (and listed in order of preference)  assembler, Cobol or Rexx.  
The java program would run on WAS and it is the program that the program on VM would need
to invoke.  We would need to pass parameters from VM to the Java program,  do something with that
data and then return the results to the calling program and display those results on a green screen.
Has anyone done this?  Are there any examples or manuals, etc. on how to do this?

Thanks,

Steve G.
