You are tired of doing all of this work by hand to create your SOAP invocation with SAAJ. You want to have Java generate everything necessary for you to invoke a service based only on its WSDL.
wsimport tool to generate the necessary
client-side stubs and invoke them as you would a regular Java
When you are new to web services the whole enterprise can be very
daunting. This discussion will walk you through the use of the
wsimport tool from a client developer’s perspective. It
will touch on schema, JAXB, and how the parts hook up together under the
hood so that you will have enough of a foundation going forward to know
which items you need to concern yourself with and what gets taken care
of for you.
wsimport tool will read the WSDL of a deployed

to think of the service as being located on the server. But a service
instance acts as a factory to create proxies that allow you to invoke a
web service as if it was local. These proxies are sometimes referred to
as SEI (Service Endpoint Interface) objects.
The tool generates portable artifacts that use only standard Java means. It will automatically call on JAXB to create value types that map Java to XML tand the result can be used to perform web services operations. ...
