If the GWT UI plugin web application won't be deployed on Engine JBoss AS instance, we'll run into cross-origin iframe communication issues that we'll need to deal with. In other words, why prevent others to "keep away" from Engine JBoss AS instance? Why not let them deploy whatever they want next to engine.ear, given that they are doing this on their own responsibility? > that's not the scope we discussed so far. > we discussed a 'static' plugin, which can use an external service or the > REST API. This was actually option [1] as described in my email below. >From WebAdmin point-of-view, UI plugins are "static", as you wrote. UI plugins >written in GWT, however, can include server-side logic on their own.
