Hello,
If you guys know a good book on Webpshere - Please suggest me (any version of WAS). I already have seen the IBM RED BOOK.
I am planning for Websphere certification.

i don�t think there books for websphere cert like java 2, swcd
there are some books on websphere but i don�t know much they r worth...handbook & infocenter looks like the best to me.. detailed & free

For the 287 exam, there is the recommended book "Developing J2EE Applications with IBM WebSphere Studio" from Kushner and others. I recently posted a question on this book in the "Products" section because I wanted a review of this book before buying it

...

the IBM WEbsphere Handbook is a pretty useful source of information. The practice tests from IBM site are the next best!
