The Makumba controller#
The Makumba controller is a component running in the 'servlet container'. When a request for a makumba page enters the servlet container, the controller will intercept the request, and perform its "controller" activities (cfr. the model-view-controller pattern) :
- authentication: check if a user is allowed to access the web-application as a whole
- authorisation: check if the user is authorised to execute the specific page
- form submission handling: in case of a form submission, perform validation (implicit and explicit), execute form-specific business logic and handle form response
- Java Business Logic
- error handling: if an error occurs (be it a programmer error or an internal error), handle the error by e.g. displaying the appropriate page
