Subject: Problem with JDBC driver: rs.next() is always null

Hello there!
I'm trying to connect to a postgresql via the JDBC interface as follow:
...
Statement st=db.createStatement();
ResultSet rs=st.executeQuery("select datname from pg_database");
while(rs.next()){
out.addItem(rs.getString(1));
}
rs.close();
st.close();
....
The JVM throws a nullPointerException.
It seems that rs.next() is null even if the result set is not empty.
I'm working with Inprise Jbuilder 4 Foundation and Redhat Linux 7.0
(kernel 2.2.16) running on my Athlon 750.
If anyone could help me I would appreciate.
P.S.:Sorry for my english!
