In the past I would have written my own JavaScript using XmlHttpRequest and a servlet on the back end. This means I have to maintain a lot of code that has nothing to do with my specific project. I evaluated several Ajax frameworks and settled on DWR for my current project. But I have a problem.
I've been writing a DWR object to act as a front controller to a web service. As I wrote previously when using DWR you write a POJO. Register the POJO in dwr.xml and the annotations take care of the rest. But, what about request scope parameters? The request is gone by the time my POJO is called...

We use the WebContextFactory to pull out context data.
