i have two application contexts 1) app.xml of a web application and 2) service.xml of a non-web application. the latter provides beans that implement a session pool of a legacy application. This pool should be used as a singleton by all applications that run in the appserver. is there a possibility to inject this service bean defined in service.xml as a singleton into a bean defined in the app.xml? would this be somhow possible with a SingletonBeanFactoryLocator? If yes, how?
