JSP files visualize specific views. I'm having a hard time imagining how you'd reuse them, but I'm not familiar with the source code of that project.
The exception would be snippets of JSP that you include in other JSPs, and thus use in many places. An examination of the source code will tell you if the project uses a lot of those.
I got this framework from google searching.i was looking for a "java technologies used" framework.In this framework it uses java technologies.
I guess I don't understand this approach. Any sizable Java product will use lots of libraries, but that generally is not of primary concern in choosing such a product. Issues such as features and support are more important, and (if you want to hack away at the source) a maintainable code base that's amenable to changes. (I am of course assuming that this is for a project that is supposed to deliver value to users; if it's entirely a learning project for you, the requirements would be different.)
