Hello Pankaj,
I am currently reading the book : Java Web Services Up and Running.
It gives you detailed knowledge on JAX-WS (
SOAP Based Webservices) and JAX-RS (RESTful web services). Definitely this book is not enough, but gives you insight in JAX-WS and JAX-RS.
This book lacks detailed explaination on following sections :
1. JAX-WS clients.
2.
Servlet and
EJB based SOAP web services.
3. WS-Security (SSL, Message level security)
4. WS-Addressing
5. UDDI
Though the book has high level overview on few of above sections.
I am preparing for Web services certification as well. I will keep posted my experience here.
Good Luck.
