I'm looking for a technology to handle a requirement that expands an existing multi tier Java web app, so that a .NET Windows tray icon app can receive data from a Java server. Any suggestions for the technologies to employ for this?

My web app has a Spring based business services tier. I have to add a server push facility that sends notifications to a .NET thick client app that will sit in the users Windows tray.

davout,

Since this forum is specific to MyEclipse related issues, I would recommend you to cross-post on relevant forums.
