How to get generate WSDL using GroovyWS

I am implementing SOAP w开发者_如何学编程eb services for a commercial application, and I am using GroovyWS to speed up the development.

But, when I deploy it on Tomcat, I am not using Grails, as the software has it's own J2EE framework, so how I do I get it to react to wsdl requests?

Do I need to write a groovy-based servlet?

Ideally I would like the WSDL generated upon request, so I can easily change the interface and see the change.

It seems I will miss the annotations that JAX-WS provides for, though, to help fine-tune the WSDL.

Using the example web application, the WSDL can be retrieved as follows:

http://localhost:6980/MathService?wsdl
