Please comment on this book...

I am thinking of buying this book to prepare these topics for XML certification.
"Building Web Services with Java: Making Sense of XML, SOAP, WSDL and UDDI"
Could anybody please tell me if its worth buying and reading as I have very less time for the preparation of this exam.
Thanks.
Vibha.

Vibha,
I think you do not need to go deep on this topic. Articles at web is far enough to cover IBM test objectives.

PS: Read the Javaranch name rules and change your id, "Vibha" is not a valid name.

Yes, I wanted to make my username as "Vibha Verma" but its seems somebody has that username already so I couldn't use it. And now if I want to edit my profile, I cannot change my username.

Vibha, could you create another account then? Unfortunately, your current name doesn't comply with our offical naming policy.

I have created a new account with last name Sharma. (Verma was my maiden name).
Thanks
Vibha.

This is the most polite, organised, well-disposed, conscientious forum on the Ranch.

Thank you, Vibha!
