Java EE (Java Enterprise Edition) General Discussion

I need to create server side classes(or servlets) to get access to a vendors API.

I will need login and session capabilities to store username/pw.

I will need to return arrays that will populate dojo components.

The vendor has samples showing the API calls using class files and I am wondering if I need to
utilize servlets at all and trying to figure out the pros and cons.

Can someone outline the main pros/cons of servlets vs class files on the server?


Thanks
Pete
