doPost() question

I am interested in creating a web app that uses JSP, Servlets and XML.

At the moment I have the following

JSP - Form input.
Servlet - Retrieving form data and sending that data to a java object.
Java object (1) - Converts data into xml file....instantiates java object (2).
Java object (2) - Sends that file to a database.

On the returning side the database will send back another XML file that I will then process using XSLT to display back to the user.

Can I place that XSLT code in the orignial Servlets doPost() method? So my doPost () method would:

1. Retrieve user inputted data from the form on my JSP page.

2. Instantiate a java object to convert that data to XML, in-turn that object will instantiates another object to send the XML file to a database.

3. Converts the resulting XML file sent from the database and displays it for the user.


Can one servlet doPost() method handle all of this? If not, how would I set up my application and classes to handle this work flow?

Thank you in advance

What part are you having problems with? Have you tried writing the code?

The problem is not really to do with coding, in fact the majority of the coding is done.

The problem is more of a design question. All I am really looking for is if the way I am handling the flow of data through the system is the correct/optimal way of doing it.

Of course a single method could handle all that--a single method can handle a lot. *Should* it handle it all? No, separate functionality should be broken out into other methods and/or classes as appropriate. It sounds like you're already doing this. So what's the problem?
