Two things:

First, given this code:

rs = JDBC_GetPrimaryKeys(dbmd: '*NULL': 'EMP': 'Employees');
dow (jdbc_nextRow(rs));
idx = 1;
Row1 = jdbc_getCol(rs: idx);
dow (idx < 6);
idx = idx + 1;
Row1 = %trim(Row1)
+ ', '
+ jdbc_getCol(rs: idx);
enddo;
except;
enddo;
jdbc_freeResult(rs);

(I have the front-end for dbmd.getPrimaryKeys() set up so that the
string "*NULL" becomes a *NULL, for both catalog and schema)

I find that I get the primary key information, but then the
jdbc_freeResult(rs) call blows up. I've got dumps, and I can do
something with them tomorrow morning.

It works with the MS SQL Server JDBC driver, but with db2jcc4.jar, I'm
getting a Java.lang.AbstractMethodError on java/sql/Statement.close()\/
Very curious. I'm getting similar errors with the result sets created
with getSchemas and getCatalogs.

Are result sets returned from dbmd.getPrimaryKeys() somehow different
from result sets returned from data?

As far as I know there is but one Java ResultSet object type.

Second, on a less-serious note, I find that if I do a getPrimaryKeys()
on AQUESTVIEW/VIEWCUS (a native keyed PF, compiled from DDS), whether
from RPG or from Java, I get an empty result set. Any idea why this
would be?

I think that getPrimaryKeys retrieves a list of primary key constraints.
With a DDS-defined file, there usually aren't any.
