java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver

I am trying to connect to a DB in java using MSSQL server.  I have followed the steps; my CLASSPATH environment variable is currently set to:

CLASSPATH=.;c:\program files\Microsoft SQL Server 2000 Driver for JDBC\lib\msbase.jar;c:\program files\Microsoft SQL Server 2000 Driver for JDBC\lib\msutil.jar;c:\program files\Microsoft SQL Server 2000 Driver for JDBC\lib\mssqlserver.jar

To verify that I have set the variable correctly I went to the command prompt and typed:

javap com.microsoft.jdbc.sqlserver.SQLServerDriver

and got:

No sourcepublic class com.microsoft.jdbc.sqlserver.SQLServerDriver extends com.microsoft.jdbc.base.BaseDriver {
    static {};
    public com.microsoft.jdbc.sqlserver.SQLServerDriver();
    public static void main(java.lang.String[]);
}

as a response which should indicate that my CLASSPATH is set up correctly.  In spite of this I am still getting a:

java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver

I have tried copying the mssqlserver.jar, msutil.jar and msbase.jar in the lib/ directory of my JDK installation folder but that did not help either.  Suggestions anyone?  Here is my source code:
