Book edition

[Shelly Gupta]

hello All,
I received the following book from my friend.
Sun Certified Enterprise Architect for J2EE Study Guide (Exam 310-051) Paul R. Allen, Joseph J. Bambara
She used to book about 2 years ago. Is there only one edition of the book (the original that was published in 2003)
Have there not been any subsequent updates?

Thanks for your help.

This book is good, however I suggest you should read following books:
1.GoF Design Patterns
2.RMH for EJB
