Stored Procedure error with JDBC:ODBC

Question

Hi,
I am trying to run a stored procedure on RDMS (Uniaccess ODBC). This has 2 input parameters and returns a resultset of 3 columns. The following is the error I am getting and am stumped. Please help..
(similar call statement works with VB and ADO)
--------output ---------------
Calling MGC005
inside resultset sun.jdbc.odbc.JdbcOdbcCallableStatement@129206
row 1
get string 0004
get string 00000
get string
SQLEcception : java.sql.SQLException: [AIS][UniAccess ODBC Driver]Invalid Column Number//Specified column is before the column specified in the previous call
----------------------source code ------------------
import java.awt.Graphics;
import java.sql.*;
public class JdbcTest {
public JdbcTest() {
     Connection con;
     CallableStatement stmt;
try {
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver");
catch (Exception ex) {
System.out.println ("Database Driver not found");
System.exit(0);
try {
String msDbUrl = "jdbc:odbc:CMS_TEST_ODBC";
con = DriverManager.getConnection(msDbUrl, user, password );
stmt = con.prepareCall("{ call MGC005(?, ?)}");
          stmt.setString( 1, "CH" );
          stmt.setString( 2, "ARRINGTON0909170320010615" );
//          stmt.registerOutParameter( 1, java.sql.Types.VARCHAR);
//          stmt.registerOutParameter( 2, java.sql.Types.VARCHAR );
//           stmt.registerOutParameter( 3, java.sql.Types.VARCHAR );
          System.out.println( "Calling MGC005 " );
     ResultSet rs = stmt.executeQuery();
          while (rs.next()) {
System.out.println( " inside resultset " + rs.getStatement() );
System.out.println( " row " + rs.getRow() );
System.out.println( " get string " + rs.getString(1) );
System.out.println( " get string " + rs.getString(2) );
System.out.println( " get string " + rs.getString(3) );
          String i = rs.getString (1);
          String s = rs.getString (2);
          String t = rs.getString (3);
String text = i + " " + s ;
System.out.println ( " Output " + text);
     stmt.close();
con.close();
} catch( SQLException ex ) {
System.out.println ("SQLEcception : " + ex);
public static void main(String[] args) {
new JdbcTest();
}

Hi,
The error seems to occur on the line:
String i = rs.getString (1);
The error exactly states what is occuring: "Specified column is before the column specified in the previous call". Try limiting the call to getString() to one for each column for each row.
Try replacing these lines:
System.out.println( " get string " + rs.getString(1) );
System.out.println( " get string " + rs.getString(2) );
System.out.println( " get string " + rs.getString(3) );
String i = rs.getString (1);
String s = rs.getString (2);
String t = rs.getString (3);
with something like:
String i = rs.getString (1);
System.out.println( " get string " + i);
String s = rs.getString (2);
System.out.println( " get string " + s);
String t = rs.getString (3);
System.out.println( " get string " + t);
Hope this works,
Kurt.
