It can be set the same way as in jboss today so that they can be overriden, and won't interfere with any existing settings: | // Include the default JBoss protocol handler package | String handlerPkgs = System.getProperty("java.protocol.handler.pkgs"); | if (handlerPkgs != null) | { | handlerPkgs += "|org.jboss.net.protocol"; | } | else | { | handlerPkgs = "org.jboss.net.protocol"; | } | System.setProperty("java.protocol.handler.pkgs", handlerPkgs); | It should be part of the vfs initialization default code.
