Where can I find Documentation about Tamino Java API ?

I want to write some servlets to access Tamino using Java API.
But I dont know how to use Java API.
Is there any documentation with some simple programs to understand how Java API works?

How about the Tamino API for Java section in the Tamino Documentation and the examples in Help\javaapi\samples supplied with Tamino 3?

But I would really like a more extensive set of documentation, covering the ins and outs of when to choose each object model, etc.

i.e., it is easy enough to get something working, but I would like a more comprehensive theoretical treatment of how to use Tamino.
