There's no DWR functionality in place, but it is installed and ready to use. Matt

Thanks for the reponse, I did some research on Ajax frameworks but could not find any hint that AjaxTags support anything like Ajax Push. However a framework called DWR seems to provide this functionality. An example is given here: http://java-x.blogspot.com/2007/03/reverse-ajax-with- direct-web-remoting.html I do not actually get how to integrate this code into my appfuse project. When I compare the code in the above mentioned example - how do I get the ServerContext there? Has anyone integrated DWR Reverse Ajax in an appfuse project? Maybe you can give me some code snippets? I also found out that appfuse already comes with the dwr library and dwr.xml. Is there already any dwr functionality in place?
