thanks a lot Mikalai Zaikin, I started with Java Web Services: Up and Running and I find this book extremely usefull.
You should also read (maybe even first) this book : "J2EE Web Services: XML SOAP WSDL UDDI WS-I JAX-RPC JAXR SAAJ JAXP" (aka RMH). It contains base knowledge for XML/XSD/Schema/SOAP/WSDL/UDDI/WS-I BP 1.0 and other specifications.
The "Java Web Services: Up and Running" book is more "lightweigh" on theory (however, it's advantage is that it covers JAX-WS and JAX-RS, which is missing in RMH book).
Also, there is Sun WebServices Blueprints book - available in PDF for free from Sun (Oracle) web site - please look at Links page.
