On a further note, new developers should look at o.w.servlets.TemplateServlet in WM 2, which provides an alternative to subclassing WMServlet. It uses an interface delegate, ServletRouter, to accept delegation calls if defined. If there is an implementation of ServletRouter, it will trap all requests. The implementation of this type is a single method handle(...) method. All of the plumbing for global processing, broker iniitialization, etc, etc, is handled in TemplateServlet. TS can serve up any type of page, including, of course, static HTML pages. The context is a web context, of course. This kind of composition I think makes it a little easier to work with a servlet and WM at the same time. -Lane Keats Kirsch wrote: > Change your code to: > > WM _wm = new WM(this); > > and you should be able to use all the WebContextTools that you care to > configure. > > Keats > > Peter Smith wrote: > >> I think I've failed to effectively communicate my >> situation.
