JDBC error

[kierandes]

Hi Guy, I am using a JDBC connection to retrieve data and populate datasets. Having some problems with errors:
Error: java.sql.SQLException: [Microsoft][ODBC Driver Manager] Invalid cursor state

          // now we can get the connection from the DriverManager
            Connection con = DriverManager.getConnection(database ,"","");
 
                //String searchPatients = G.PatientSearch.getText();
 
            // We are connected, so lets create a statement to ask for names from our table "names"
            Statement s = con.createStatement();
            Statement s2 = con.createStatement();
 
 
            s.execute("select Username  from Usernames");
            s2.execute("select Password from Usernames");
 
            // Execute and get the results
 
            //rs2 is to get the Ward of the patient
            ResultSet rs = s.getResultSet();// Patient Name Verification
            ResultSet rs2 = s2.getResultSet(); // Ward name
 
            if (rs != null) {
                // If we had results, loop through them...
                while ( rs.next() )
                {
 
 
 
                   // resultset1 = rs.getString(1);
               String RS2,strUsername, strPassword;
 
                RS1 = rs.getString("Username" );
                 RS2 = rs2.getString("Password" );
                 strUsername = txtUsername.getText();
                 strPassword = txtPassword.getText();
 
                //SearchString = txtSearch.getText();
                int rowNum;
                int rowFind;
 
 
 
 
                    // Just prints out the values
                  if(RS1.equals(strUsername))// Filters by Name
                 {
                  //First check that the name is on the list
                    System.out.println(strUsername);// rints the name
 
                 //  int rowrs1 =  rs.getRow();// Get the row number of the successful entry
 
                   // the next part gets the Ward of the patient
                   // all depending on the row number of the first condition set
                   // with rs - the first result set.
                   // I got the row number of the set then
                   // when rs2 cycles through the database, if its row number
                   // is equal to the row number of the first rs - row number successful search
                   // it will print the details, eg ward and later on the room number
 
                  // int rowrs3 =  rs3.getRow();// gets the row number of the 3rd result set
                  // while ( rs2.next() )
 
                   //                 {
//                     System.out.println("success");
 
                    //                }// end of rs3 While statement
                  } //end of if on result set1 Name Filter
 
 
 
 
                }
            }
 
            // Cleanup our statement and connection by closing them.
            s.close();
            con.close();
        }
 
        // If there was an error connection or querying, show the error.
        catch (Exception e) {
            System.out.println("Error: " + e);
        }
 
 
 
 
 
    return null;
 
    }
 

Maybe there is something I am missing. any help would be greatly appreciated.

Make your code print out the complete stack trace; it contains line numbers and all; in your catch clause do this:

e.printStackTrace();
 

... so you can see where exactly that exception was thrown.

kind regards,

Jos

Thanks Jos,
I'll implement that right away :)
