I think you'd have to set up a second prototype with a different prototype name but the same EXTPROC. That prototype would handle the expanded parameter list. The JNI mechanisms should handle the overload.

Subject: Expanding JDBCR4 -- can somebody refresh my memory

It seems that I'm going to have to add some more things to Scott
Klement's JDBCR4: I need to expose the 2-parameter
Connection.createStatement() (currently, only the zero-parameter version
of the method is exposed), and write a variant of the JDBC_ExecQry() ILE
RPG function, using it to return a result set of type
"ResultSet.TYPE_SCROLL_SENSITIVE."

I'm trying (on inadequate sleep) to remember how I did similar things
the last time, when I was expanding the amount of meta-data available to
RPG, but I don't know if I had to deal with method name overloading before.
