patrick,

the straightforward way to do that is through the JMX api, there is the jboss.system:service=MainDeployer which has two operations :

- Collection listDeployed() which returns a list of org.jboss.system.deployment.DeploymentInfo objects, each object having an URL attribute you can use to locate your deployment

- redeploy(URL url) or redeploy(String) which force a redeploy of the specified archive, you can locate your archive URL by using the listDeployed() operation
