AW: converting Rexx CGI to NetRexx

[Thomas.Schneider]

Hello Eric,

   your question goes beyond the scope of my knowledge. You will probably
have to implement CA1CALL parm in JAVA. I do NOT know whether there is a way
to connect to CICS thru JAVA. IF this is possible, then both NetRexx and
Rexx2Nrxwill have no troubles (as thay all result in Java Code).

I am forwarding your query to the NetRexx users group. maybe somebody in
the group has the answer ....

  to the second part of your question: YES, you can deply your netRexx
program like any other websphere application.

  Let me know the result of your efforts.

Hope this helps.
Tom .

Hi Thomas,

long ago that I did work in that environment, but I try to give answers  
as good as possible. The last part you already answered and I must  
agree. The other questions is how to call a load module. CICS is a  
different kind of animal in that it has got its own linkage  
conventions, memory allocation and the likes. Also, CICS programs must  
be reenterable. Now assume that the mentioned program CA1DCALL adheres  
to these conventions, then for a CICS systems programmer it would not  
be too difficult to make a JNI 'glue' routine that picks up the  
parameters, stuffs a pointer in register 1 (or uses a CICS command for  
that) and calls the program. As JNI is geared to C perhaps there should  
be another level inbetween (easier would be to call the C interfacing  
routine to CICS).

I have heard some time ago that there is a CICS to Java gateway that  
uses the ECI Interface. Perhaps he should Google for that?

best regards

Rene Vincent Jansen
