How to write files into the root context

[tophermiller]

My root web application context is deployed outside of a war file. I want my web application to be able to write new files into this directory tree. So, I need to obtain a java.io.File object that points to the root of my web application. However, this path varies from server to server. Is there a way I can get this path from the JBoss API somehow?

You can get the server root path from the System properties in this manner:

String homePath=System.getProperty("jboss.server.home.dir");

There is a list of system properties set by JBoss in the documentation at this page:

Be aware that the Java SecurityManager may prevent you from reading and writing System properties, in which case you have to grant yourself those priviledges.
