Hi everybody, we have built a modular application platform using OSGi.
To us it is important not only to build modules in the service layer but also in the GUI layer. Our GUI is a web application and we decided to deploy it as a WAB. We are using ZK Ria as web application framework. Everything works fine with regard to reference other bundles from our WAB up to the controller layer. But when it comes to serve static resources from the WAB we are not very happy with our solution. We would like to separate the static resources also in bundles analogue to the modularization of the business and controller layer. But WAB does only support loading resources from the WAB itself and its fragment bundles. So for every business module we build a fragment bundle with its appendant resources such as HTML, CSS, JPGs ... But using fragments leads to loosing dynamic since we cannot activate/deactivate the fragments. But we would like to activate/deactivate, install/uninstall modules at run time. Servlet specification 3.0 allows loading of resources from jar files in WEB-INF/lib if they are located in META-INF/resources inside the jar. Since imported packages of the WAB are (nearly) treated like jars in WEB-INF/lib in a servlet container I was wondering if I can import META-INF/resources from another bundle and load resources from it. Of course one has to use a servlet 3.0 conform container. I have not found anything about this topic in the WAB spec. Some experiments with Gemini 2.0 were not successful. I have read that GlassFish supports this approach. Should the WAB spec cover this topic? Or is it up to the implementers such as Gemini or PAX web to deal with it? Or is there another solution for loading static resources from modules?
