That is not a proper UNC name for accessing a file on a share on another Windows system. First, on host B you need to define a network share. For this example lets call that share myapps. You need to place the apps you want to deploy into the local directory identified by the network share. For example, on B you have a directory c:/myapps and you share it as myapps. Then copy the app (hsqldb-ds.xml in this case) to that directory - it then appears in the share. Then you need to ensure that the account that is being used to run JBossAS on host A has access rights to that share. Then you can use this URL to deploy the app: "file://B/myapps/hsqldb-ds.xml" View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4167765#...
