This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
The product is good if you already have knowledge in certification topics like JAX-WS, JAXP...etc.
Though they say complete study guide I feel there are lot of topics with only review tips and not covered in depth.
The latest training lab version for oce web services is very good in terms of theory and mock exams.
