Stephane MALDINI smaldini@doc4web.com \ ICEpush is a notification framework, it doesn't carry data unlike Cometd. However you can register callbacks such as page/fragment refresh and script invokation. By combining 1 Tag and 1 Call (from javascript/ser/ver side), you add a new dimension in your webware. You can push, join/leave channels from controllers/gsp and add support for services. This plugin can be mixed with the coming ICEfaces 2 integration to allow collaborative application scaffolding and push capabilities for JSF2. http://grails.org/plugin/icepush BuildConfig DataSource UrlMappings org.doc4web.grails.icepush.IcepushTagLib
