Hi,
I've been working on a web application that consists of jsp's beans and 1 servlet as the controller. I read somewhere that all I need is 1 servlet as the controller. The servlet is getting pretty big. Should I use 1 servlet as just the controller and then uses some other servlets to handle actions, or is it okay that this one servlet is getting pretty big?
Thanks,
Sean

Couldn't give a perfect answer, but in previous projects the only time we had a single servlet acting as the controller for the entire application was when the flow of control was clearly defined.
That is, there was a clear path that the user had to follow and there was little ability for them to go outside this. Therefore, by having a single controller they were forced to take one step after another regardless of the Servlet the thought they were requesting.

To my knowledge, you can have a number of servlets in your application as controllers.
You could design different servlets to be invoked based on user action/business funtion/etc. This way you could have smaller (sized) servlets that accomplish your task.

why don't you just use a configuration file and put the action classes you want to load in there ?? like;
com.mybuziness.sate.ActionWhatever
create a new instance of it and forward ?

I think the BEST solutions for you would be to use a ready made MVC system!! Take a look at STRUTS!!

Thanks for all the replies. I appreciate all your answers. I was just wondering what other people thought. I checked out struts. It's looks pretty useful. I wanted to create an application following the MVC pattern. It's coming along quite nicely, although my controller servlet is getting a bit bulky, so I just wanted to know what other people did when they came into this situation. I figure I can keep the bulky controller servlet, or keep one strict controller servlet and have a few more smaller servlets that handle requests for specific actions. I'm not sure what I'll do yet though. Thanks for your input.
