To the author:
Does the book provide an explanation of the conceptual reasons for the enhancements in
Struts 2 from Struts 1 ?. Like
thread safe action class - eliminating the need to pass the arguments in the execute() method, etc.
Does it provide details into the Ajax related Structs 2.1 enhancements, like the retriveUrl() method? Last time I read a book on "Struts with Ajax", the Ajax was mentioned in only one chapter - 12 pages (out of which 8 pages are just code). In this book the responseXML was generated in the brute-force way. I guess Struts has some inherent support for Ajax, where the action invoked from a form, after doing all the business logic and getting the updated form attributes, updates/renders the form with the responseXML - without much work for the developer to parse the responseXML and repopulate the form. Please advise if your book goes into this.
