There is no benefit for most developers. The JSP Document Format ("xml style") is intended for use internally by JSP containers and for automated tools that generate JSP files, in which the JSP can be built up into a DOM and serialized. It is not intended to be used by developers who are directly writing JSP pages.
And where I can find the resource to learn xml style jsp.
If, for some reason you need this info, it's all in the JSP Specification.
Secondly The current version of JSP is 2.1 and Servlet 2.5 Why there is no book for it.
Books take a long time to write. There isn't a whole lot that's different from JSP 2.0 ad Servlets 2.5, but if you need the exact info, again, the respective Specifications are where you can find it.
Your old post is the answer for my new question. But in the Demo of JSF in Netbeans v6, the TravelCenter sample. Sun did use JSP Document for implementing JSP pages... It's a litle bit confusing to me [ May 13, 2008: Message edited by: BiA Vn ]
