I also encountered the same problem dealing with Collection classes. How are you defining your de/serialiaers for Collection in ur wsdd file?
Rather than passing back any collections, convert them into an array of javabeans, and pass that around.
I do that for my C# clients and Java webservice, and it works.
I have learned that I need collections on the server side, but seldom on the client side. Generally the array will work well, but it is easy to create a client-side collection from an array.
