Guillaume Grossetie [https://community.jboss.org/people/grossetieg] created the discussion "[Proposal] Resolve expression values on system properties" To view the discussion, visit: https://community.jboss.org/message/759709#759709 -------------------------------------------------------------- Hi, The StringPropertyReplacer class already provide a method #replaceProperties that replace ${expression} value with system properties. I think that it can be useful to resolve expression on system properties with system properties. Example :     <system-properties>         <property name="my.image.dir" value="${jboss.server.data.dir}/image"/>     </system-properties> Sure I can do the work on my code but I don't want to reference jboss system property :     <system-properties>         <property name="my.image.dir" value="image"/>     </system-properties>   System.getProperty("jboss.server.data.dir") + "/" + System.getProperty("my.image.dir"); If we use StringPropertyReplacer we can also do sometthing like :     <system-properties>         <property name="my.dir" value="/my/dir"/>         <property name="my.image.dir" value="${my.dir:/home}/image"/>     </system-properties> The basic idea is to check if the added/removed/changed system property resolve expression : setSystemProperty("my.image.dir", "${jboss.server.data.dir}/image"); # my.image.dir = "${jboss.server.data.dir}/image"   setSystemProperty("jboss.server.data.dir", "/opt/jboss"); # retrieve my.image.dir property, resolve expression and setSystemProperty("my.image.dir", "/opt/jboss/image"); # my.image.dir = /opt/jboss/image The resolved expression will not be stored on the standalone.xml/domain.xml file. What do you think ?
