Re: Executing a jar file from RPG

Peter,

A JAR file is not much more than a ZIP file containing a bunch of Java class files. The JAR file itself is not executable, *but* you can run the classes inside the JAR file (without unzipping them).

So you will need to know the Java class name to run. This would be true if you were executing it from Java or anywhere else as well... nothing to do with RPG. It's just the way JAR files were designed.

Has anyone had the need to run java from RPG thru a jar file?

I have a java product for which the instruction is to launch by running
a jar file directly as opposed to a java class.

The i5 supports this technique via the JAVA cmd which will accept either
a class or jar.

But is there a way to implement this from RPG similar to calling the
Main method of a java class.
