Excellent work, Jim，

If you can also comment on the relationship between the java2wsdl and 
java2cs, that will be great
IMHO, the java2wsdl does support the jaxws, and simple frontend, but 
it's only generate the wsdl, is it the duplicate function in the java2cs,
Or is it possible to extend the java2wsdl (we need to find a better name 
for it)
Or java2cs will call into the java2wsdl to generate the wsdl files, and 
associate the artifacts (like the beans/binding files in case of jaxws)

And the java2cs should also generate the configuration files, right? 
(spring, servlet etc.), and also we need have the ant tasks, so 
generating artifacts, and then compile, deploy, all in one command.

All in all, looks a good plan :)

> Goal
> ----------
> 1. Generate jaxws frontend client server code and wsdl from Jaxws 
> conformed classes
> 2. Generate simple frontend client server code and wsdl from Pojo 
> class . Tool can generate and compile interface class or impl class

>
> Tool Description
> -----------
> Tool Name : java2cs
> Description : takes a user defined class to generate jaxws or simple 
> frontend client and server side code
> Options : -cp classpath to load the user defined classes
> -server generate server side code only, if client and server is not 
> specified , both client and server code will be generated
> -client generate client side code only
> -frontend jaxws or simple , default is simple frontend. which control 
> to generate jaxws and simple style server and client
> -databinding jaxb or aegis databinding. jaxws frontend will use jaxb 
> databinding and simple frontend will use aegis databinding by default .
> -wsdl control to generate wsdl.
> class the full class name used to generate client and server
