You can set the response code using Response.setCode.

I am not sure what your are asking here?

Anywhere within the context root the current working
directory or anywhere the Locator can reach. Look at
simple.http.serve.FileLocator.

System.setProperty("simple.http.load.mapper","simple.http.load.PatternMapper");

Edit the mapper.xml file, its loaded once on startup.

One instance is created, if the TemplateEngine will
reload the class if it is modified though. I would set
a Controller attribute. For example:

controller.set("core", new Core());

And within the ActionService.prepare acquire the
instance doing the following:

core = (Core) system.get("core");
