Deploying to BlueMix: "The application failed to stage, so there are no instances to display."

Hi all,

I'm trying to deploy a simple web project with a web page just to test BlueMix, little background:

-I created a web project and a web page on RAD and using EGit I push them to a Git hosted repo on JazzHub.
-Since I don't have the manifest.yml file, I created it manually on JazzHub
-Then I enable the auto-deployment option on JazzHub and here seems to be good, I see an OK message and the log only have "OK" on it.

But if I click the link I get this error: 404 Not Found: Requested route ('web1-54106f54-a340-465e-9f67-e4262ad5814e.ng.bluemix.net') does not exist.

And if I click on the Manage on BlueMix link on the Instance Details section I see this error: The application failed to stage, so there are no instances to display.

BTW, this is the content of the manifest.yml:

---
applications:
- name: Web1
  memory: 512M
  instances: 1
  host: Web1-${random-word}
  path: Web1EAR/Web1.war

Someone has faced this problem before?
Thanks
