My target audience for the book was Java developers who were familiar with JSP and Servlets, but were new to intermediate level to Struts.
The book was not targeted for high, high-end developers. (As some of my reviewers have commented at amazon. ) We cover a lot of topics beyond the basics (good design, design pattern usage in Struts...), but we do not go into detail about really extending Struts tag libraries our ripping out pieces of Struts and replacing your own functionality.
I was looking to write a book that was not a copy of the on-line documentation. If you are looking for a high-end Struts book that really gets into the guts of the extending Struts and customizing Struts you might want to try "The Struts Survival Guide." Its a very thin book, but the sample chapters I downloaded were impressive.
