Comparing the Stacks What they have in common abstract stack machines (runtime type control, exception handling, garbage collection) rich base class libraries The most obvious difference Java 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 generics Java has added annotations (analogous to.NET’s attributes)

Does it really work?

.NET StockTrader Example Equivalent to IBM Websphere 6.1 Stock Trader application Same services exposed

Web UI Services Layer SOAP

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 partnership A part of Sun’s Glassfish initiative (open source JEE5 server) – Project Metro Goal: 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 routing WS-Security, WS-Trust, WS-SecurityPolicy for secure messaging MTOM and XOP for attachment encoding WS-ReliableMessaging, WS-Coordination and WS- AtomicTransaction for reliability and transactions For more information: ProjectTango/ ProjectTango/ ProjectTango/
