Sun's most advanced certification program in Java technology is - Sun Certified Enterprise Architect for Java 2 Platform. Please refer to the Sun's site for more details. Given below are some of the good books that may be used to prepare for the Sun Certified Enterprise Architect for Java exam.
In March 2002 the first book on SCEA was released. Sun Certified Enterprise Architect for J2EE Technology Study Guide by Mark Cade, Simon Roberts is a good buy for this exam. Though the book by no means is sufficient to prepare for the exam, it covers useful information on many technologies. You will probably need to read some of the other books, and then read this book.
The only other certification book on SCEA is Sun Certified Enterprise Architect for J2EE Study Guide (Exam 310-051)
by Paul Allen and Joseph Bambara. The book does not cover the objectives in great depth. It is also
not too well organized. But since there are so few books available for this tough exam, you may consider buying
this book too.
These other books are not specific to SCEA but are all classics that you should consider buying if you are a (budding) J2EE architect.
