Its almost exactly the same with Wookie using custom features - there are some step-by-step instructions here on how to inject JS into Wookie widgets by creating a new feature spec: http://incubator.apache.org/wookie/docs/developer/features.html That should work without needing to modify anything in Rave. > >> -> Where must i start to get my Custom Code to get Loaded by RAVE each >> Time widgets gets Displayed? >> -> Where is my entrypoint to get famililar with the RAVE-Source Code? >> (Already followed the instructions on the Webpage, Eclipse is ready to run >> with RAVE). >> >> The Basic Idea is to send Events from the Widgets over OpenAjax pubsub to >> the portal-Page and implement a Training Environment storing the learned >> Events and Destinations in RAVE's Database according to the logged-in user. >> > > As a general note, Rave already supports OpenAjaxHub for IWC.

Add the following line to your Widget's config.xml file: <feature name="http://www.openajax.org/hub";> ... and you can then call "hub.publish" and "hub.subscribe" from your Widget's javascript. > > Chris > >> >> Tanks for Your Help, >> >> Christian >>
