Since JSP2.0 has added a number of changes in the structure, such as changes the internal structure of JSP, the JSP page not only requires static PARSE, but also collects Attribute Action defined in the generation process, and Attribute Action Can be any JSP element, even Cutom Tag, Fragment this makes everything more complicated and more powerful.
There is also the joining of Tag File, and how it affects JSP with the Simple Tag Handler with it. I want to think about this back.
