Servlet representation in a UML diagram

[Reema Patel]

Hey,
I have little knowldge of UML diagrams. I know that to represent a class, we use rectangular boxes and inteface implementationis represented by dotted lines.

That said, what's the stand notation used to represent a servlet. The sertver that I need to represent is an ordinary servlet and not really a controller.

Pls...help...

Just the familiar rectangular box is fine. Take a look at any Servlet source code ... it probably implements Servlet or extends some abstract framework class. You could choose to show those if you thought the reader needed to know or omit them if it's not important to your story.

If you think the fact that it is a servlet should stand out, you could also use a stereotype.

But remember that you should model for purpose - and your model should only contain those things that are vital for that purpose.

Thanks Stan and Ilja Preuss for your comments.

What exactly is a stereotype?

My servlets directly extend from the HttpServlet, and I'm using a diamond box to represent a servlet in UML, hope this is fine.

Thanks again

Standard UML notations may not have all the notation that you are looking for. In which case you may want to create your own notation.

Example: Regular classes as retangular box with sharp edges.
and
Servlets as rectangular box with round edges, which will stand out.

your choice.

With a stereotype, it would look like this:

+---------------+
|  <<Servlet>>  |
| FooController |
+---------------+
+---------------+
