Hi John, the java toolbox has certain restrictions for invoking service
programs. One of them is the return value data type, the other is a limit
of 7 parameters. Just be aware a data structure with many fields would
still count as one pararmeter.

I use PCML to call service program procedures from Java all the time and have found that judicious use of data structures is a very simple way of getting around the parameter count limit.

I came up with a technique that let me use externally described data structures (PF's on the iSeries, same ones the RPG code used) to make passing complex data from Java to RPG quite easy.
