Servlet using Tamino Java API

Does anyone have a working Servlet which uses Tamino Java API for simple querying…

I can make a Java program work with Tamino Java API. Porting the same program to servlets gives me some errors. I know there is something I am missing, so if some one has a example servlet he can point me to, I would appreciate that.

I have a servlet using Tamino Java API. It works like an standard application. I can send it to you (specify your e-mail) or you can send me your servlet by mail for see it.

Hi Sumeet,
Here’s a sample of a simple insert servlet. You would have to create a simple input HTML form and Tamino database to run it. Hope this helps you.
Keep in touch.
