Hi Santosh, Best book .. RMH J2EE webservices read it throughly also the appendix chapters too.
Read the webservice desiging blueprint except for XML processing read all the other chapters.
Go through Mikliha Zaikin web site for web services preparation excellent resource.
Read basic profile 1.0 Specs .Very improtatnt . Go to the link for Basic profile 1.0
Read SOA search in yahoo and just read about SOA etc.
Read other resources you can for security. I read very extensively for security. SAML ,XKMS specs but u dont need really such details but I wasnt getting any really good resource at that time. I passed so this must have worked. :-)
According to me, material needed is : - RMH J2EE Web Services book ( a must-have) - real life experience with Web Services projects
