Subject Re: DI in 3.1
Date Fri, 05 Oct 2012 06:50:51 GMT

The entry point to Cayenne in 3.1 is ServerRuntime. If you already have CayenneFilter elsewhere
in the application, it means ServerRuntime is already created and can be retrieved by your
code outside of HttpRequest:

ServletContext servletContext = // you can get this one during app initialization (or maybe
Spring can inject it?)
CayenneRuntime runtime = WebUtil.getCayenneRuntime(servletContext);
ObjectContext newContext = runtime.getContext();

does not pass throught CayenneFilter and there is no context attached, so I need to be able
to create context on demand for those cases and that is changed to DI in 3.1 wich is undocummented
afaik, I have tried with:

how Cayenne DI is working or how can I create a new context at 3.1?
