Comparing the Stacks
What they have in commonabstract stack machines (runtime type control, exception handling, garbage collection)rich base class libraries
The most obvious differenceJava supports one language on multiple OS.Net is language neutral (20+ supported) on one OS
The main .NET languages (C#/VB) and Java are advancing along similar paths, e.g.
Both now have genericsJava has added annotations (analogous to .NET’s attributes)

Does it really work?

True Interop
Services in the application are exposed, via WCF, as industry-standard Web Services.
The .NET StockTrader Web application seamlessly interoperates with the backend J2EE services of the WebSphere Trade 6.1 application
Conversely, the WebSphere Trade 6.1 Web application is able to seamlessly utilize the backend services of the .NET StockTrader. In each case, a simple endpoint configuration allows this interoperability, with no code changes required to either application.NET StockTrader and J2EE Interoperability
How about something more
complex?
Project Tango (WSIT)Sun-Microsoft partnershipA part of Sun’s Glassfish initiative (open source JEE5 server) – Project MetroGoal: Java™ technology Web Services interoperability with .NET 3.0. (showcased at JavaOne)
Accomplished by fully interoperable implementations of:
WS-Addressing, WS-Transfer, WS-MetadataExchange and WS-Policy for discovery and routingWS-Security, WS-Trust, WS-SecurityPolicy for secure messagingMTOM and XOP for attachment encodingWS-ReliableMessaging, WS-Coordination and WS-AtomicTransaction for reliability and transactions
