JSP precompilation

Precompiling the JSPs when you "build" the application is very important for user interface response times. If the JSPs are not precompiled, the application servers compile the JSP on-the-fly the first time it is used. These compiles can take up to 30 seconds or more and could lead to the perceptions of a badly performing system.
