AFAIK it is not possible or even deep in JBoss internals.
But what is the intention behind the question, normaly you might able to deploy your app exploded to the hdscanner directories.
Thanks for your advice.
Indeed, our team has to deploy a system (.war format) to other parties which some of them use tomcat, some of them use jboss, some of them use others. As system has to customise custom properties for each party, another program has been developed to code with this. However, the program has to know the path of deployed war files, that's what we are confusing when jboss is used. If JBoss has no such configuration, I think we have to report to team manager and suggest to use exploded deployment instead.
