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!
