Hi!
First, a shameless plug of a electronic book I have written, which can be downloaded for free (registration required):
http://www.slideshare.net/krizsan/scdjws-5-study-notes-3085287
There is a step-by-step explanation of WSDL in the early parts of the book.

Then some additional resources:
Create contract-first (WSDL-first) web services with Spring WS: http://static.springsource.org/spring-ws/site/reference/html/index.html
Creating a WSDL-first web service with Apache CXF or GlassFish: http://www.jroller.com/gmazza/entry/web_service_tutorial

Best wishes!
