This is for a Windows system. From the research I have found I know you need to register a program with the SAP Gateway. The program is an RFC server program. Need to use SM59 to setup the destination, choose Register Server Program and put the name of the program under Start on Application Server. I have seen an example RFC Server program from SAP. I have seen the use of this command to register the program in the 

OS (Unix): rfcexec -g -a -x

I know you can view if it is running using SMGW. What I don't know is if the RFC Server program is the Java program you want to execute or just a listener that then is used to kick off your Java program. Also, I think I have to get the rfcexec program from the NW RFC SDK files? I would have thought the JCO library should have everything you need to call SAP and call Java. I have been able to use the example Java program to call an SAP RFC but I want to go from ABAP to Java now. What am I missing?

  • As it is stated right now, the question is way too broad to be answered in the short Q&A format of stack overflow. Can you narrow your problem down and thus improve your question? – vwegert Nov 03 '16 at 22:00
  • I changed it and tried to eliminate what I know to narrow it down to what I need to know. Difficult when you don't know the answer. – JDel Nov 04 '16 at 19:20
