Our company is moving some components to our internal cloud and I am working in a project and one of the task is to expose an existing legacy java class as soap web service. Can anyone please help me stir in the right direction? How can I write a soap Producer on existing new class and methods? Should I write a new class and extend this class or should I write a subclass? What is the best way to approach this?I am new to integration projects. The company is using Mule Esb as an integration solution? Also how Mule esb fitst together with all this?I am new to Mule esb.
