I don't know what is wrong with my previous topic.

Exploded ears work fine from within the deploy directory.
Anyway, I want to know why my application can't deploy on /home/jboss/applications/EarContent.ear directory, not $server/$server_name/deploy.

I've got :
org.jboss.deployment.DeploymentException: No META-INF/application.xml found

The URL is a regular directory, with a sub-dir META-INF and a proper application.xml.

There is a comment in jboss-service.xml under conf:
- Scanning is supported for remote URLs but unpacked deployment units are not.

Is my case related above comment?
If it supports an EAR what is only packaged, it doesn't have any flexibility for many users who want to use external service directory.

I really want to get an correct answer for this.
