mvc using servlets and jsp
I have heard a lot about mvc that how helpful it is. Please explain how can a servlet be used as a controller? Are all database connections reqd for the application opened only on the controller servlet? Can any other jsp page or servlet not be used for receiving data from db?
How does a controller servlet handle all user requests?
If I am not able to explain what I want to know then please explain the process of building a webapp using mvc with servlets, jsp's and java beans in a step wise manner. I'd like to thank you all in advance.
