RE: Passing Messages

This sounds like the "right" way to do it.

I am a java/linux programmer, so anything about RPG sounds complex.

Would there be a "Hello World" example for RPG/JNI ?

Once I get that, I think I can better understand the "ILE RPG Programmer's
Guide"

You could use JNI and write a simple RPG wrapper program to call your
java program, and have the java method you call return a string, and
then return that string in one of the parameters of the RPG program.
Then have your CL call that RPG program and read that parameter for the
result. That's actually not as complex as it sounds. Information about
calling java methods from RPG can be found in the ILE RPG Programmer's
Guide.

Something to consider.

What is a good way to pass a message from a java program to CL ?

You can pass parameters in when calling RUNJVA, but how can you get a
parameter out ?

Here is what I have tried to do:
        1. In CL create a data-area in qtemp
        2. Call RUNJVA, this java program would write to the newly
created
data-area in qtemp
        3. CL would read a message from this data-area
        4. When CL ends the data-area in qtemp dis-appears

        The problem here is that the java program in step 2 can not read
the
data-area created in step 1.

I guess I'll try and use a db2 table instead of a data-area if no-one
has a
better idea.

Thanks
