This has been discussed a number of times before on this list.
Suffice it to say that overriding service() is a bad idea, and you're
better off overriding/implementing doGet() and/or doPost(). Check the
list archives for details (basically the default service() provides a
lot, and it's silly to throw it all away). If you are OK with having
the same behavior with GET and POST, there is nothing wrong with
implementing one of them and having the other one call it (or you
could have them both call some other method).

I would ask you to look more closely at why you want to do this,
there's a decent chance it means something is wrong with your design.
That is, why do you want to have one servlet call another's doPost()
method? If it's to take advantage of some functionality that that
method already implements, perhaps the better solution is to have a
third class, perhaps not a servlet at all, but a standalone class of
some sort, that implements that functionality for both servlets. If
it's to call that servlet as a normal HTTP request/response
transaction, then perhaps you should be using RequestDispatcher or
(Http)URLConnection.

Just code the call in, I don't see what the problem is. For example,
a doGet() can consist of nothing but a call to the doPost() (or
vice-versa).
