Invoking Managed Bean at a Page Level

Question

I know JSF is component based, but I have a situation where I am writing an application using Nagios ( http://www.nagios.org ), which is an OSS network monitoring tool. The tool monitors/notifies systems (db, ldap, mq, etc) using unique URL's.
I've written a backing bean which takes the URL parameters to decide which system to test.
The URL is:
http://localhost:8080/start.faces?system=mysql
The code in start.faces is:
String system = (String)request.getParameter("system");
FacesContext ctx = FacesContext.getCurrentInstance();               
Application app = ctx.getApplication();
app.createValueBinding("#{monitor.system}").setValue(ctx,system);
//TODO: figure out how to invoke testAction() from here rather than using commandLink belowRight now i'm putting the parameter into a command link that I click manually to invoke the backing bean:
<h:form id="formSubmit" >
     <h:commandLink value="Call testAction()"
                    action="#{monitor.testAction}" >
          <f:param name="system" value="#{monitor.system}" />
     </h:commandLink>
</h:form>     While this is fine while I am developing the app, it won't work with a tool that only submits http requests.
What I'd like to do is to call the testAction() from the URL (as is shown in "TODO" above). It seems like there should be a way to invoke the testAction() method from the faces context, but I haven't been able to figure out how.
Any Ideas???

If I am understanding the problem correctly, inserting the following code will allow you to access the backing bean (monitor) and its methods... You may have to tweak it so it works with your own object.
          MonitorBean mb = (MonitorBean)FacesContext.getCurrentInstance().getExternalContext().
               getApplicationMap().get("monitor");
          String action = mb.testAction();HTH,
