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.
We are still contemplating the upgrade from Java 6 to 7 and we currently develop using Oracle's JDeveloper. In addition, I am new to web service development. Is there much difference between JDeveloper and NetBeans IDE? Which version should we begin with? I noticed the book indicates we should use NetBeans 7. Will we be able to upgrade our Java 6 web services to 7 via our WSDLs alone or are further considerations necessary?
