Name
Monolithic/Compound JSPs
Mistake
A single JSP page performs duties of model, view, and controller, making the page large and difficult to maintain.
Watch for It When
JSP pages are large and complicated, JSP pages contain a large amount of embedded logic, JSP pages directly connect to databases or other external resources, or JSP pages contain lots of if/then statements.
Solution
Refactor into the MVC architecture. Separate all output generation into JSP pages or separate servlets. Separate calls to business data into reusable actions. Coordinate input processing, actions, and views with servlets.
