I guess this is what I meant: (all) incoming parameters would be put to
Context - like those for the action method. Presently, this can be
achieved by overriding ActionServlet.handle() method:

public Template handle(HttpServletRequest request,
                        HttpServletResponse response,
                        Context context) {
    for (Enumeration e = request.getParameterNames();
         e.hasMoreElements(); ) {
       String name = (String) e.nextElement();
       String[] values = request.getParameterValues(name);
       context.put(name, values.length == 1? (Object) values[0]: values);
    }

    return super.handle(request, response, context);
}

1) you can access servlet instance in your components:

public class MyComponent {
    private YourServlet servlet;

    public MyComponent(YourServlet servlet) {
       this.servlet = servlet.
    }

    public Template myMethod(String name) {
       servlet.getTemplate(name);
    }
}

2) you can put $ActionServlet into Ccontext:

public Template handle(HttpServletRequest request,
                        HttpServletResponse response,
                        Context context) {
    context.put("ActionServlet", this);
    return super.handle(request, response, context);
}

3) you can access ActionServlet instance in ActionConfig:

public class ActionServletInstantiator implements Instantiator {
    private ActionServlet servlet;

    public DefaultInstantiator(ActionServlet servlet) {
        this.servlet = servlet;
    }

    public Object createComponent(Context context,
                                  Class componentClass,
                                  String componentName) {
       return servlet;
    }
}

<component name="servlet"
            class="org.actionframework.ActionServlet"
            instantiator="ActionServletInstantiator "
            persistence="application">
    <action name="/getTemplate" method="getTemplate(String name)"/>
</component>

Or did you mean something else? :)

Good! I will take a look.
