As GrayMan suggested, Servlets are intended to be used for HTTP communication.
If you want to open common logic to multiple clients, use EJBs, CORBA or some type of Web Service (SOAP, XML-RPC).
When you send a request to a servlet, the doPost or doGet method will be invoked. Products such as STRUTS allow you do 'map' to other classes. I suggest avoiding this.
Personally, I avoid STRUTS like a bad disease. Using STRUTS instead of just learning Servlets/JSP adds a lot of overhead. I prefer performance over development time. A good example of this is that ANY request that comes in over the WEB has ALL variables from the calling page (text boxes, radio buttons and such) made avaialable through the HttpServletRequest.getParameter(String parameterName) method. STRUTS requires you to build a subclass of it's ActionForm classes that is nothing more than a JavaBean with fields that match that of the web page. STRUTS will look at all the parameters in the request and all the fields in the Bean and assign any matches from the request to the Bean. The Bean is instanciated and the matching logic performed just to give you access to objects you already have access to.
Just my 2 cents, avoid STRUTS like an STD.
