Article: Simple JAVA and .NET SOA interoperability
.NET and Java interop can be made really simple using a REST documentcentric approach. This article compares a REST and SOAP approach to interop as well as the advantages of using HTTP POST vs. GET for REST invocations.

One step further towards REST
If you are interested in going even further towards a RESTful design, I suggest that you have a look at the Restlet open source project that we are actively developping. It aims to be a fully featured and RESTful alternative to Servlets/JSP and other WS-* stacks.
It has integrated support for XML representations (both reading and writing) as well as content negotiation, all HTTP methods (including DELETE, PUT, MOVE, etc.) and is even protocol agnostic (currently supports HTTP client and server, SMTP, FILE, JDBC).
dev.mainsoft.com offers free edition of their .NET --> Java tools which allows compiling .NET to JVM bytecode, as well as fully interoperable and open source (Mono) WebServices and Remoting .NET --> Java.
A simpler protocol, microcalls
I've used microcalls in lots of production projects and worked very well for me and my team.
Take a look.
