You will need a wrapper of a sort. As stated in the manual "The response from the post should be JavaScript that
manipulates the form or creates and populates data structures.". So, you'll have to code and call service side script
that in turn calls java servlet and then turns around and reports the result to DC Form.

Another alternative would be to use AJAX and call your servlet directly without using callServer alltogether

If it is possbile please let me know in detail.

If you are still talking about the call from FormAPI, the answer is no, not directly anyway.
Please note that FormAPI is a Java Script, you (probably) meant some method of Java Class.
If that's the case you still can do it with the wrapper.

If you are no longer planning to communicate to servlet from FormAPI you would have to elaborate more on your requirements and environment

You can certainly make a call from FormAPI CallServer method to a servlet.
You may follow this example -
var params = new Object();
params.param1 = value1;
params.param2 = value2;
IWDatacapture.callServer("/iw-cc/myServlet?",params,true);

I am using this in TS 6.5 SP2 and it's working without any issue.

You may extract the parameters at servlet end by request.getParameter("name") method.

Hope this helps.

Absolutely correct if the servlet has been designed for the FormAPI callServer request.

If however he's trying to utilize existing servlet built for different Clients then some sort of wrapper/adapter is the way to go.
If nothing else, it would allow for DC Form callback without modifying existing servlet API
