I am in the process of learning web services using axis2. I have some confusion regarding wsgen, wsimport, java2wsdl and wsdl2java.
Q1) If I have a wsdl I can use wsdl2java or wsimport to get the server side classes and then implement them, what is the difference between using wsgen and wsdl2java? I know wsgen uses the JAX WS programming model, then which model is wsdl2java using?
Q2) If I have a annotated java class and use wsgen, I get the wsdl and some java classes, what is the purpose of these java classes as without them also I can package my annotated java class to a jar and then deploy it in the servicejars directory.
