However, it must be noted that the book doesn't cover all the objectives of SCDJWS 5. Although, I haven't done any detailed mapping of the book to the objectives, I think it covers parts of sections 4, 5, 7, 8, 9 of the objectives.
Some one has posted a link to SCDJWS links on this website. It is also important to note that some of those links are outdated for the new exam. In addition to the book, you might want to look at, 1. http://java.sun.com/webservices/technologies/index.jsp (be sure to visit all tabs and all links) for Java EE parts of the exam 2. Standards specifications e.g. SOAP 1.2 spec etc. for other parts of the exam
