Converting WCF web service to Java

I currently have a web service built on WCF. It's still in its infancy, so, major changes are still possible. I've been thinking on porting it from WCF to a Java-based solution since I'd like to have a Linux-based backend. What would be the best way to accomplish this "conversio开发者_开发百科n"? Any advantages WCF may have that Java lacks?

Alternatively, you could run your existing WCF services under Linux using Mono, the open source implementation of the .NET framework.

See this SO question for links to sources of information.
