Application scope services

[sodium <so...@yahoo.com>]

Just few quick questions. I've skim through the documentation as well as the
only Tap5 book i recently bought and i didn't find any reference to this. 

Is it possible to bind some sort of services using Tap5 when the container
init the Tap5 application? Also, is it possible to have those services
declared in application scope? For instance, i wanted the application to
constantly check for incoming sms from mobile connected via javacomm.

And also, I was looking at the ajax documentation. It didn't state whether
if the ajax supported is secured or not. I only wanted authenticated user to
be able to call the ajax. Is this possible with Tap5 at the moment?

Hi,

I had a similar needs before, what I did is, write a scheduler using Quarts,
then initialize it at time of IOC start up:

// Start the SMSScheduler from IOC
   
    public static void
contributeRegistryStartup(OrderedConfiguration<Runnable>
            configuration, final SMSScheduler scheduler) {
        configuration.add("SMSSchedulerStartup", new Runnable() {
            public void run() {
                try {
                    scheduler.run();
                } catch (SchedulerException e) {
                    e.printStackTrace();
                }
            }
        });
    }

Yes, absolutely. Have a look at the tapestry-ioc documentation.

I'd do that with the help of quartz. The third-party component library Chenillekit has support for 
it IIRC. Also search the list archive (tapestry.markmail.org), there has been some discussion about 
Tapestry and Quart in the past.

Sure. Use the if component and only render ajax-enabled components if the user is authenticated.
