When it comes to web services interoperability between .NET and Java, the choice used to be limited to SOAP over HTTP. This became even more limited with introduction of .NET 3.0 because only BasicHTTP binding in .NET provides direct interoperability with Java Web Services.
Two new options recently became available in this area – WebSphere MQ (WMQ) and ActiveMQ transports can now be used for building interoperable web services between Java and .NET. Moreover, reliable messaging for .NET is now extended. In addition to MSMQ, both WMQ and Active MQ can now be used as reliable transport for .NET Web Services.
