I would like to deploy several versions of the same .war file. The way I would like to do this is to have the current app.war file in the /deploy directory and then all the older versions of the app.war file in a different directory. Then have it so I can access all of these versions on the web like so:

/deploy/app.war maps to http://myserver:port/app
/deploy/versionX.1/app.war maps to http://myserver:port/versionX.1/app
/deploy/versionX.2/app.war maps to http://myserver:port/versionX.2/app

When I try this I get the following error:

java.lang.IllegalArgumentException: addChild Child name '/app.war' is not unique
.......

Thanks in advance for any help
