So I have my EAR file and I want to hot-deploy it to my running JBoss server. The server has been configured within Eclipse for my project and I can start/stop it, messages come in the console etc.

When I right-click on the EAR and select Deploy To.. I get the Target Choice window which correctly displays my JBoss configuration. However when I click on OK to deploy the ear, I get a error window pop-up which says "An internal error occurred during: "Deployment of myApp.EAR". The Details button is disabled.

When I look in the log file, this is what it says:

!ENTRY org.eclipse.core.runtime 4 2 2005-11-17 15:05:42.388
!MESSAGE An internal error occurred during: "Deployment of myApp.ear".
!STACK 0
