I've built an application with ZOPE and would like to create a Java interface to it (probably using jpython/wxWindows) Here's how it should work: When changes are made on the ZOPE site by a client, a notification is sent from ZOPE to the Java interface and displayed in real-time. The idea here is not to have a continually refreshing Java window, but a window which updates only when it receives a message from the site to do so. What I don't know is how to send the data from ZOPE to the Java client. Can anyone point me to any existing ZOPE Products/Projects/How-To's which are similar to what I've described, or perhaps point me in the right direction?
