Searching for 'jsp compile' in online help has the following to say:
...Compile all JSP files in a project. In the Projects window, right-click the project node, choose Properties, click Compiling, and select the Test compile all JSP files during builds checkbox. Close the Project Properties dialog box, right-click the project node, and choose Build Project from the pop-up menu.
By default, the IDE does not compile JSP files while building a project. This is because JSP compilation can take a long time because JSP files have to be translated to servlets before they can be compiled....
