I've taken the exam on Wed-19th. Here are my suggestions:
1. Make sure you are comfortable with methods(names and params.. not too much but you must be able to differentiate between 4 similar ones from the choices). Also, make sure which class the methods belong to you might have to choose from one of the options in the test. 2. Security chapter from Blueprints has really helped me. Read the entire blueprints (to be able to answer architecture questions) 3. Have a look at high-level architectures of JAX-RPC, JAXB etc etc... (How is it designed, how is it supposed to work) 4. There were a few questions on pure J2EE architecture (nothing to do with webservices). 5. One good thing is, the questions are all grouped.. So, if a question is about JAXB, you can be sure that atleast the next 10 questions will be from same topic 6. Distribution of questions was even. 7. There were a couple of questions about what BP allows. I more or less guessed 8. In the deployment questions, look at the directory structure and what files contain what.(you dont have to spend too much time here though) 9. Focus on xml namespaces and their scope.
