How can I access the exposed methods in a .wsdl file using Java? Also, what are the steps involved in writing a Java client and consuming the webservices?
.wsdl
I would recommend starting with the Web Service Explorer in Eclipse Java EE. This allows you to investigate any web service given the WSDL.
The instructions to convert the WSDL to Java depends on which web service library you want to use. If you use Java 6 the Metro stack is built in.
