ClassNotFound Exception using JWSDK for JSP

Hello all
I am trying to connect to Oracle Database
which is on Unix M/c from windows using a jsp file
I m using JWSDK
But it throws a Runtime Exception on this line of code
Class.forName("oracle.jdbc.odbc.OracleDriver");
Exception is ::
java.lang.ClassNotFoundException: Unable to load class
oracle.jdbc.odbc.OracleDriver
I have added the classes111.zip file to the CLASSPATH
which contains this class.
I then wrote a small .java file with the Connection code
with the classes111.zip in the CLASSPATH and this is working
fine
Can someone help me why the Exception is thrown when run using
jwsdk
Has anybody experienced any similar problem

"Rahul S",
The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at http://www.javaranch.com/name.jsp . We require names to have at least two words, separated by a space, and strongly recommend that you use your full real name. Please choose a new name which meets the requirements.
Thanks.

Hi,
You will have to add the classes.zip path to the CLASSPATH for the JSWDK. Modify the file "startserver.bat" and append to the classpath.

But i hv already done so and still its not working
I modified the startserver batch file
What other could be the reason
Somebody please help :-(
