Problem in connecting to DB2 using JDBC

[sirisha alam]

I am trying to connect to DB2 database from java and am getting the fllowing error.
java.lang.ClassNotFoundException: com.ibm.db2.jcc.DB2Driver
I have set the required classpath. And here is the code that i am trying to use:
import java.io.*;
import java.sql.*;
public class SingleDBConnect
{
static SingleDBConnect dbConnection = null;
private Connection con = null;

private SingleDBConnect()
{
try
{
Class.forName("com.ibm.db2.jcc.DB2Driver");
con = DriverManager.getConnection("jdbc b2:univ", "db2admin", "db2admin");
}
catch(ClassNotFoundException ex)
{
System.out.println("Exception in SingleDBConnect : " + ex);
}
catch(SQLException ex)
{
System.out.println("SQLException : " + ex);
}
}
public static Connection getConnection()
{
if( dbConnection == null )
{
dbConnection = new SingleDBConnect();
}
return dbConnection.con;
}
}
Please advise me on this.

what happens if you place on top:
import com.ibm.db2.jcc.DB2Driver;
