The implementation files for the webservice are pre-existing.
Used the Java2WSDL of WAS to generate the WSDL file.
Used the RAD Webservice wizard to generate the java implementation files and the server deployment files.
Removed the implementation files and replaced them with the pre-existing implementation files already present.
Made the change to point to the correct impl file in the web.xml. Deployed the code.
The error is helper classes are not found.
If I do the same above steps in WAS6.1 it works perfectly with the helper classes getting generated when I try to deploy the app. But the same is not happening in WAS 5.1.
Please suggest me as to what needs to be done to make it work.
