I have searched for "J2EE Web Services: XML SOAP WSDL UDDI WS-I JAX-RPC JAXR SAAJ JAXP" by Richard Monson-Haefel in Amazon and it seems to be based on J2EE 1.4 spec. Is there any other book specifically designed for version 5.0
Yes, the RMH book is slightly old, but it is nevertheless a very good introduction to web services.
If you have little or no experience with web services, then it is a good starting point.
You can skip the chapters that deal with matters irrelevant to the new version of the certification.
