Unable to load driver

[Praveen Potineni]

Hi all,
I have some problem loading the driver. I think i have put the driver files in a wrong 
place. When i run the code which looks like this:

 private String myDriver ="com.sybase.jdbc2.jdbc.SybDriver";
...
...
...
...

try{
      Class.forName(myDriver).newInstance();
     }
  catch(Exception e){          
   throw new InstantiationException("Unable to load myDriver:"+e.toString());
  }

I am getting this error below:

Exception java.lang.InstantiationException: Unable to load 
myDriver:java.lang.ClassNotFoundException: com.sybase.jdbc2.jdbc.SybDriver 
I am using tomcat 3.3 here...

Can some one suggest me where i have to include the driver files to make it work... 
And the environment variable CLASSPATH 
=C:\jakarta-tomcat-3.3\lib\common\servlet.jar;C:\jakarta-tomcat-3.3\webapps\examples\WEB-INF\classes;C:\Program
 Files\Sybase\SQL Anywhere 7\java\jdbcdrv.zip;c:\Program 
Files\Sybase\jConnect\classes\jconn2.jar

Thanks
Praveen
