Good news. Martin Kalin has just published the second edition of Java Web Service Up and Running.
I want to ask if I should read this second edition instead of the first edition?
I am studying his first edition for my version 6 exam.
I would just stick to the first edition if you have already bought it, because the topics of the second edition are the same. It is a nice book to get to get to know Web services but, as you probably already know, it won't help you with all the topics on the exam.
