I am a somewhat newbie with java and sql.  I've run into something
that seems odd, maybe even wrong (!).

	Statement seq = db.createStatement ();
	seq.execute ("SELECT nextval ('cdid')");
	ResultSet rs = seq.getResultSet ();
	id = rs.getInt (0 + 1);			<=========

The SQL works fine directly in psql.  All other SQL statements seem to
work.  But getInt, in this case, gets a NullPointerException.  Here's
the stack dump:

Exception occurred during event dispatching:
        at postgresql.ResultSet.getString(
        at postgresql.ResultSet.getInt(
        at postgresql.ResultSet.getInt(

If I change the argument to 0, I get

	java.sql.SQLException: Column Index out of range

I tried 'nextval' too, and got the same SQLException.

Am I doing something wrong here?

This is PostgresQL 6.3.2, Linux 2.0.33, glibc, and linux jdk 1.1.5v5
glibc.  I have no problems with the Perl program which does the same
operation many places.
