I'm setting a bunch of system properties like so: | <mbean code="org.jboss.varia.property.SystemPropertiesService" | name="jboss.util:type=Service,name=SystemProperties"> | <attribute name="URLList">conf/x.properties,conf/y.properties</attribute> | </mbean> | Within those property files I'd ideally like to be able to reference previously set properties, e.g. foo.dir=${jboss.server.home.dir}/foo | bar.dir=${foo.dir}/bar | ... | Any ideas if this is possible somehow? The SystemPropertiesService API docs do mention something about interpolating properties, but that's not in the setURLList method but in setProperties, which takes a Properties object directly rather than a list of files...
