Summary:                    system-property tag works fine in the foreground
while fail in the background
Description: 
i need run two instances (processes) on one host (machine) for the same one
web application.
noly just do it like this:
${RESIN_HOME}/bin/httpd.sh -conf ${APP_ROOT_DIR}/resin-active.conf
${RESIN_HOME}/bin/httpd.sh -conf ${APP_ROOT_DIR}/resin-standby.conf

the different configuration items between resin-active.conf and
resin-standby.conf are as follows:
(1) watchdog listenning port: 6800 in resin-active.conf while 6801 in
resin-standby.conf
(2) http listenning port: 8080 in resin-active.conf while 8081 in
resin-standby.conf
(3) stdout and stderr log file
(4) others ...

i don't want these differences hidden in everywhere of the resin.conf file,
so i put them together 
(take them as user-defined variables using system-property tag) on head
lines of the resin.conf.

take resin-active.conf for example, define variables first: 

<resin xmlns="http://caucho.com/ns/resin"            
       xmlns:resin="http://caucho.com/ns/resin/core">
       
<!--node sensitive configuration items in user applications --> 
<system-property mynode.watchdog.port="6801"/>
<system-property mynode.http.port="8081"/>
<system-property mynode.jmx.host="10.10.79.144"/>
<system-property mynode.jmx.port="10087"/>
<system-property mynode.gc.logfile="/opt/adlog/resin-gc-standby.log"/>

<system-property mynode.app.webroot="/root/forecast/WebRoot"/>
<system-property mynode.app.stdout="/opt/adlog/resin-stdout-standby.log"/>
<system-property mynode.app.stderr="/opt/adlog/resin-stder-standby.log"/>

<system-property mynode.app.node="node-standby"/>
<system-property mynode.app.logback="logback-standby.xml"/>

...

then reference the variable where you need

<server-default>                                    
      <!-- The http port 8080 -->                   
      <http address="*" port="${mynode.http.port}"/>
...

it works fine when resin runs in the foreground while fail in the
background (no error prompts, watch-dog starts successfully but web-app
unloaded)
in other words:
execute the command ${RESIN_HOME}/bin/httpd.sh -conf
${APP_ROOT_DIR}/resin-active.conf   OK
while ${RESIN_HOME}/bin/httpd.sh -conf ${APP_ROOT_DIR}/resin-active.conf
start     FAIL

i wander when and where the out-of-the-box variable ${resin.professional}
or ${resin.root} of the following snippet is initialized ?

<management path="${resin.root}/admin">                    
    <user name="admin" password="password" disable="true"/>
                                                           
    <resin:if test="${resin.professional}">                
      <deploy-service/>                                    
      <jmx-service/>                                       
      <log-service/>                                       
      <xa-log-service/>                                    
    </resin:if>                                            
  </management>                                            
  
thanks
