Hey, after talking with Tristan Tarrant from Infinispan I got the idea, that we could create a generic Portlet, that gets its content data as HTML from a server plugin. The server plugin then has access to all the server logic to do its task and can e.g. compute various stats of an Infinispan cluster. The following drawing illustrates that idea: Instances of the portlet will call to the selected server plugin and invoking a well known "interface" like "getMessage". This message will then do the processing and return a HTML-snippet (not a full page), which is then displayed inside the portlet window. Attached are two screen shots from such a portlet + some PoC code. This is created in the backend via (abbreviated) complexResults.put(new PropertySimple("results", "<h1>Hello World</h1>Welcome to RHQ<br/>Have FUN<br/>Current date: " + date)); This is the "generic" config screen: The drop down shows the list of plugins available. In this PoC, the plugin writer is responsible for creating sane HTML, if we decided to put that into RHQ, we may want to do some additional sanitation. I also have no idea about styling the inner content. While this is probably not the way for the (long term) future, at least the backend plugins can be re-used if we move to an Angular-based UI, so this investment would not be lost. Heiko
