So far I have been very unimpressed by Cade & Roberts' book. The coverage of topics is too lightweight to be sufficient for exam study, and if you just need a guide to what you need to know Sun's own SCEA Part I exam objectives are fine. Also, it misses out whole sections of the objectives (e.g. Messaging) and that's very poor for what is supposed to be a guide to the exam.
Maybe it is better for part 2? I hope so... [ August 26, 2004: Message edited by: Ben Ritchie ]
I agree with the other posters. The book is very useful for an idea of what is acceptable for part II but the best resource for part I is to search for information on the web for the areas mentioned in the exam objectives. There are lots of SCEA link pages out there too.
