Trying to connect to DB2 database....get windows Application error message

Question

Hello,
I have just started using JDBC and I am trying to connect to a DB2 db from my pc. The program I have written compiles ok but when I try to run the program I get a windows error:
java.exe - Application error
The instruction at "0x10009f62" referenced memory at "0x0000001c". The memory could not be "read".
Click OK to terminate the program.
Click CANCEL to debug the program.
I am using Windows2000 and DB2 v6.1.0 is installed on my laptop.
The program I am trying to run is as follows:
//Class to load jdbc driver and test connectivity to DB
import java.io.*;
import java.util.*;
import java.sql.*;
//Dynamic SQL application using jdbc
//example taken from Don Chamberlain's book, page 504
//Adjusted for reptest DB
public class Test{
//Register the jdbc driver
static{
try{
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
}//ends try
catch (Exception e){
System.out.println("Error registering the jdbc driver");
e.printStackTrace();
}//ends catch
}//ends static
public static void main(String args[]){
//try catch block, Create a Connection object and use it to connect to the DB and turn autocommit off
//The DB is identified by a URl that begins with "jdbc:db2" followed by the DB name
try{
String dbname = "dbname";
String userid = "uid";
String pw = "password";
String url = "jdbc:db2:" + dbname;
Connection con = DriverManager.getConnection(url, userid, pw);
con.setAutoCommit(false);
//Simple select statement
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT problem_id" + "FROM problems" + "WHERE problem_id = 2002219");
System.out.println(rs.getString(1));
}//end try
//General purpose exception
catch(Exception e){
System.out.println("Error");
e.printStackTrace();
}//ends outer catch
System.out.println("Successful");
}//ends main
}//ends class
I'd appreciate any help. Thanks , Ali

Hello,
This is because of the DB2Java.zip file, what i did is unzip the file into a temp folder then make a jar using jar -cvf DB2java.jar COM
(COM is important)now you can see jar file is created. you have to use this jar file in your classpath it works fine,
That's all it works for me.
Thanks for somebody placed in the java forum.
Cheers
