Little variance in my scrores with respect to each objective category ... Questoins on WSDL were no-brainers ... More UDDI questions that I had anticipated ... Still trying to figure out why there were 6 or 7 EJB questions.
Hardest exam I've ever taken, including anything I saw in college.
The material is out there. You'll have to do some searching though. I found RMH's book the most important of all. Now that there will be a book out specifically for the exam, (I believe the author is Habibi), perhaps you should start there. For me, the most difficult part was actually building web services. Most of the products out there are not as mature as they could be. I ran into bug after bug, which really taxed my learning efforts. I became well aquainted with JBoss, Jonas, Sun 1 AS and various versions of Tomcat in order to implement/practice the exam objectives. None of these products will let you implement everything you'll need to know for the exam alone. Does this answer your questions? Also, the study materials by MZ helped me as well.
