Subject: jdbc can't getResult of "select nextval (seq_name)"

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:
java.lang.NullPointerException:
at postgresql.ResultSet.getString(ResultSet.java:161)
at postgresql.ResultSet.getInt(ResultSet.java:241)
at postgresql.ResultSet.getInt(ResultSet.java:569)
...
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.
