I am getting a hang of what stripes is all about. Having used none of the frameworks, this question might apply to something like struts as well.
We have a home grown MVC which has a servlet as the single point of entry into the application. This servlet not only decides what to do next, but also make sure the proper security is enforced and so on.
How would something like this implemented with stripes, as the form submission takes the control to the actionlistener and specific methods.
Stripes also works this way: when a request comes in, Stripes determines which Action Bean and which event handler method will handle the request.
For security, you can implement an interceptor, which is code that runs for every request at specific times in the Stripes lifecycle. This is easier to do than writing a servlet filter, and is tightly integrated within Stripes.
