Callable Statement Exception

Question

Hi,
I am very new to Java SQL Callable Statement.
The following is the program that i wrote to execute a Stored Procedure stored in MS SQL Server 2000.
In my program I am actually retrieving back the value that I've passed to the MS SQL Server.
========================================
import java.sql.*;
import java.sql.Types;
public class CallableTester
     private Connection connection;
     public CallableTester(Connection conn)
          connection = conn;
     public void executeInsert ()
     CallableStatement stmt = null;
     String sqlstmt;
     int rows;
     try {
          sqlstmt = "{ ? = call product(?, ?, ?, ?) }";
          stmt = connection.prepareCall(sqlstmt);
          stmt.setString(1, "61");
          stmt.setString(2, "62");
          stmt.setString(3, "63");
          stmt.setString(4, "67");
          stmt.registerOutParameter(1, Types.VARCHAR);
          stmt.executeUpdate();
          connection.commit();
          System.out.println("The value inserted are " + stmt.getString(1));
          stmt.close();
          System.out.println(sqlstmt);
     catch (Exception e){
          e.printStackTrace();
=========================================
The is no syntax error.
When I run the program, I've got the following exception
java.sql.SQLException: [Microsoft][ODBC SQL Server Driver]COUNT field incorrect
or syntax error
at sun.jdbc.odbc.JdbcOdbc.createSQLException(JdbcOdbc.java:6106)

at DatabaseConnection.makeConnection(DatabaseConnection.java:22)
at Start.main(Start.java:16)
=========================================
My database has a table named Product with the following fields and properties.
Field id of type varchar
Field name of type varchar
Field costPrice of type decimal
Field sellPrice of type decimal.
=========================================
The stored procedure for this table is
CREATE PROCEDURE product @id varchar(8) = 8, @name varchar(50) = "productName", @costprice decimal = 88, @sellprice decimal =168 AS
INSERT INTO PRODUCT VALUES(@id, @name, @costprice, @sellprice, @desc)
GO
=========================================
Can anyone please to help me? I have been trying to solve this problem few days but I really can't.
Your help will be appreciated.
Thank you very much.

I've reproduced your code with some modifications to make it work, I've tested it against a Sybase DB which is close enough to MS SQL Server.
First the procedure. Note that I create and write to a temp table you can ignore this.
create proc dmjtest
  @id varchar(8) = '8',
  @name varchar(50) = 'Dave Jenkins',
  @costPrice decimal = 1.23,
  @sellPrice decimal = 4.56
as
begin
  declare @rc int
  select @rc = 0
  create table #t (
    id varchar(8),
    name varchar(50),
    costPrice decimal,
    sellPrice decimal
  insert #t values (@id, @name, @costPrice, @sellPrice)
  if @@error = 0 select @rc = 1
  drop table #t
  return @rc
endNow for the java code
import java.sql.*;
import java.sql.Types;
public class CallableTester
  private Connection connection;
  public CallableTester(Connection conn) {
    connection = conn;
  public void executeInsert () {
    CallableStatement stmt = null;
    String sqlstmt;
    int rows;
    try {
      stmt = connection.prepareCall("{ ? = call dmjtest(?, ?, ?, ?) }");
      stmt.registerOutParameter(1, Types.INTEGER);
      stmt.setString(2, "1");
      stmt.setString(3, "product 1");
      stmt.setDouble(4, 63.0);
      stmt.setDouble(5, 67.0);
      stmt.executeUpdate();
      connection.commit();
      System.out.println("The return value is " + stmt.getInt(1));
      stmt.close();
    catch (Exception e){
      e.printStackTrace();
}
