# JBoss 5

Convention plugin support

To have proper support of ﻿﻿the Convention Plugin in JBoss AS 5, especially when you put actions inside a jar (which is embedded in war or ear) and not directly into `WEB-INF/classes`, you must add the following line into `$JBOSS_HOME/bin/run.conf` or into `$JBOSS_HOME\bin\run.conf.bat` Linux/OSX - $JBOSS_HOME/bin/run.conf

    JAVA_OPTS="$JAVA_OPTS -Djboss.vfs.forceVfsJar=true"

Windows - $JBOSS_HOME\bin\run.conf.bat

    set "JAVA_OPTS=%JAVA_OPTS% -Djboss.vfs.forceVfsJar=true"

You can find more details about JBoss VFS here^[http://docs.jboss.org/jbossas/docs/Installation_And_Getting_Started_Guide/5/html_single/index.html#d0e495].
