Servlets are meant to be the Controller in the MVC design pattern and JSPs are meant to be the view.

The main purpose in using Servlets as the controller is to seperate the view from the logic. It makes code a lot cleaner and easier to maintain.

So, in an ideal world, page designers (with no programming skills) can just write JSPs containing no code, just tags that they and their GUI-based design tools understand.

That leaves us server-side programmers (who may have no talent for, or interest in, page design, i.e. me!) to write the code for servlets and beans and leave the arty-farty, pretty stuff to those who care.

Where did that turkey come from?
JSP are a way to make servlets that is optimized for writing HTML pages. In case you have not noticed, there is a lot more to the Internet than HTML pages.
If you want to serve binary data - images, sound, zip files, etc. servlets are the method of choice. Not to mention all the services such as SOAP that can be built on a servlet base.
