Re: RPG Web Service Program

All,

I write RPG (and SQLRPGLE) programs all of the time that I then attach to be used as Web Services. No issues there.

However, I now have a need for the web service program to call a Java process. When I compile the program as a "regular" program I receive no errors. However, when I change the Ctl-Opt to read PgmInfo(*PCML:*Module), as I do for all of my other web service's programs, I receive a RNF0302, Errors were found while generating the program information to be placed in the module.

That's the entire extent of the information. No more. Unlike my previous RPG service programs that were "pure RPG", this does have prototypes for the Java, Java class declarations, creation of Java objects, and such, but that is all needed for RPG to make the call to the Java class.

Has anyone successfully created an RPG program, as a web service, where that web service then directly calls a Java class in the IFS? This must be possible, right? I feel like I am missing something very obvious inside of my RPG program but can't figure out what.

Any and all thoughts and ideas, as always, are very welcomed. I really don't want to have to add another layer: an RPG program as a web service, calling another RPG program that call the Java process - that seems really silly, but at this point it also seems like the only possible way to succeed in this process.

Hope that everyone is staying safe and healthy.

Thanks,

Steve Meisinger
