It looks as though to long road to publication of the above might be nearing its end! For those of you that don't know this was originallly a Wrox Press book, but after their collapse was taken on by Apress!
Currently, we are looking at a September release, so still well ahead of most JSP 2.0 books.
The JSP 2.0 spec is pretty exciting, as it provides some new and powerful features to JSP developers. These include:
A powerful Expression Language
The JSP Standard Tag Library
More powerful and flexible ways to develop custom tags
