Subject: RE: NullPointerException when using JDBC ResultSet next()

I apologize but I posted the wrong code. Here is the correct code. Line 45
is rs.next. I am not sure that the driver has loaded properly. How can I
tell?
Thanks.
import java.io.*;
import
sorry, but you called
ResultSet rset = stmt.executeQuery (select sc_id from bug_status_codes);
and then used
rs.next()
maybe they must be all rs or all rset.
Bye

sorry, but you
to the rset but call rs.next().
So rs is null.

ResultSet rs = null
You sure that your test table has a test column? Change rs.getString
(test) to rs.getString(1) to see if that works...
HTH

The stack trace says that your NullPointer occurs on line 45, but line
45 is blank. Is there some more code that you didn't ost? Import
statements, perhaps?
I think it probably happened here:
stmt = con.createStatement();
-IE: You were not able to get a Connection, con is null and calling
();
}
catch(SQLException ignored) { }
}
}
};
