The requirement suggests to put JSP and servlet on the component diagram. Is that right? Shouldn't JSPs and servlets be put on class diagram? I can easily find class diagram with JSP and servlet but rarely a component diagram showing JSPs and servlets. Second, the requirement suggests showing interactions among component on the component diagram. But UML spec1.4 defines component diagram to show dependency while a deployment diagram seems to be the one that shows runtime interaction. Both Rose and Together don't provide link line representing interaction in their component diagram. Together5.5 only provides "Dependency" line in its component diagram and "Association" line in deployment diagram. Rose only provides dependency line in its component diagram. Deployment diagram should be the diagram showing interaction among components. Am I missing something? Thanks for your comment!
