Too sad that I can't just set the response code easy as servlet api
does, will you consider to provide this feature in future release?

Haven't notice that some interface API haven't been implemented...

Where should this mapper.xml put so that simple can load?
Is it possible for me to set these information at code? I think I can use

System.setProperty("simple.http.load.mapper","simple.http.load.PatternMappe=
r");

To set the mapper using, but how can I change the resolve properties
that mapper.xml tell the system?

Another question is how many instance will the ActionService created?
Will it create a new instance for every request, or it act like
servlet, create one instance then run the process() method many time
to serve difference request? For now, my application like this:


public class Controller extends ActionService {
=09final private core.Context ctx;
=09public Controller(Context context) {
=09=09super(context);
=09=09try {
=09=09=09final File file =3D new File("WEB-INF/data/");
=09=09=09this.ctx =3D new core.Context(file);
=09=09} catch (Exception e) {
=09=09=09throw new RuntimeException(e);
=09=09}
=09}

=09protected void finalize() throws Throwable {
=09=09super.finalize();
=09=09ctx.shutdown();
=09}

=09private void handleRequest(Request req, Response res, Document document)=
;

=09public void process(Request request, Response response) throws Exception=
 {
=09=09try {
=09=09=09handleRequest(request, response, system.lookup("template.vm"));
=09=09} catch (Exception e) {
=09=09=09throw new RuntimeException(e);
=09=09}
=09}

=09public static void main(String[] list) throws Exception {
=09=09TemplateEngine engine =3D new TemplateEngine(new FileContext(), new
VelocityContainer(new TemplateManager().engine()));
=09=09Connection connection =3D ConnectionFactory.getConnection(engine);
=09=09connection.connect(new ServerSocket(8082));
=09}
}

Where
=09final private core.Context ctx
should only created once for the application, if Controller will
create may time then I need to think difference implement, and now I
use finalizer to trigger the clean up, which is not work in most case.
Just wonder if simple provide standard way for me to clean up
application if the user quit?
