Problem with deploy-hasingleton and applications

[adrian.brock]

deploy-hasingleton is deployed through a -service.xml

It treats the whole directory structure as a single nested deployment.
This means that if deploy-hasingleton contains applications
they will often be attempted to be deployed before their dependent
service is deployed.

e.g. put an mdb in deploy-hasingleton, it will fail initially because
HAJNDI is not in place. It will work 10 seconds later when it is and
the MDB tries to reconnect.

This sounds like its treating the deploy directory as an archive url vs a directory url. This same behavior is seen when not including a trailing '/' on the URLDeploymentScanner so perhaps its a similar configuration issue.

[adrian.brock]

No it is deliberate.

Currently it passes the URL directly to the MainDeployer.

I'd suggest it adds/removes it from the URLDeploymentScanner?

I'm running 4.0.4GA retrofitted with ejb3 RC8 and Seam 1.0.1x

I just created an example hasingleton, i have an example.sar file that seems to be ignored if I drop it into the deploy-hasingleton dir, but seems to function if I drag it into the deploy dir.

In the deploy dir it constructs, and the startSingleton method is called. I see it on the jmx-console, and start/stop work from there - but I'm not convinced I actually had an hasingleton... Did I? Haven't tested in the cluster yet.

I think I need one in order to fire a message into the cluster periodically. The hasingleton w/perhaps quartz seemed like a good idea to solve this problem. Am I on the right track?

How do you deploy an hasingleton?
How do you KNOW its working?
Was the deploy-hasingleton dir ignored?
Does the farm exist? who turned it off? why?

Or perhaps, the question is really - which chapter did I miss?

Thanks

The deploy-hasingleton directory is not scanned for hot deployment.

You could try this also for a simple hasingleton
