SQLException "No Result Set"... Sometimes

Question

i'm trying to learn how-to use the whole JDBC package and what not, and i thought i had stumbled onto a real problem, but now its just confusing....
i can connect with no problem to the database. i then tried to query the table COFFEES but kept getting java.sql.SQLException: No REsultSet Produced**. then i tried to "create table" and - surprise- NO PROBLEMS! it then "insert into table" that i had created by sql and again no problems, i then quereied some data i had entered (by sql) into the table i created (by sql) and it worked. but whatever i try to do with the one i created in M$ Access XP seems to #@%&! up. tho i can view both table perfectly in Access w/ no prob
does anyone know what is wrong? the only think i can think of is that M$ changed the file format of its Access DBs when it released office XP and that the ODBC thinger has the drivers for the old format and so the table i create by sql are done in the old format and can be read in Access b/c of reverse-compatibility... any ideas, comments, suggestions, patches, etc. anyone?
** i created the table in M$ Access XP Pro. Ed. on Win XP Pro. w/ all the updates and stuff, i'm using that ODBC Adminstrator thing that comes w/ XP i don't really know what it is but i got instructiosn from some tutorial

Answer 1

yeah, apparently less is working than i thought, here is what i have. its not really anything coherent as i�m just playing around trying to learn whats going on:
PS - im a n3wb
import java.sql.*;
public class SQLTest {
    public static void main(String[] args) {
        Connection con;
        try {Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");}
        catch (ClassNotFoundException e)
            {System.err.println ("JDBC-ODBC Bridge NOT found");}
        try {
            con = DriverManager.getConnection("jdbc:odbc:mage");                     
            Statement stmt = con.createStatement();           
            //created table using this: "create table employee (first varchar(15))";
            String upd = "insert into employee (first) values ('Luke')";
            int rts = stmt.executeUpdate (upd);                                 
            String query = "select * from employee where first = 'Luke'";
            System.out.println("Query: " + query);
            ResultSet rs = stmt.executeQuery(query);           
            boolean bob = rs.first();
            do {
                System.out.println(rs.getString ("irst"));
                boolean obo = rs.next();
            } while (!rs.isLast());
            con.close();           
        catch (SQLException e)
            {System.out.println ("ERR: " + e.getMessage());}
    }//end main (String [])
}//end class
