RE: D-Specs for Java Prototypes in RPG

In any prototype, the "type" field to the right of the PR says whether
anything is returned.  It could be any type, including integer or alpha, or,
in this case an object (type "O").  Notice that the prototype for pkgMethod
doesn't have a type of "O" in the prototype line.

If this is truly a void method, just remove the "O" from the prototype line.

As to returning a boolean primitive (little b), simply code the return type
as "N" (indicator).  For more on this, check here:

There's a ton of information on RPG/Java interoperation there.
