Manually configuring domain.xml using ${name} and -Dname

Question

I need to be able to use this syntax:
      <jms-service addresslist-behavior="random" addresslist-iterations="3" init-timeout-in-seconds="60" reconnect-attempts="3" reconnect-enabled="true" reconnect-interval-in-seconds="60" type="LOCAL">
        <jms-host admin-password="admin" admin-user-name="admin" host="${com.memento.localhost}" name="default_JMS_host" port="7676"/>
      </jms-service>When I add -Dcom.memento.localhost="%COMPUTERNAME%" to the script that runs CLIMain, the property is not replaced when the above jms-service element is processed. I know because the server.log shows:
#|2005-03-16T17:00:39.809-0500|INFO|sun-appserver-pe8.1|javax.enterprise.system.stream.out|_ThreadID=10;|
URL is :mq://${com.memento.localhost}:7676/,Where do I set my property so it is picked up for replacement in domain.xml? Apparently the Java command that runs CLIMain is not the right place. Or soemthing else is wrong?

Answer 1

If I understand this correctly, you need to do a token replacement so that the runtime accepts the configured value.
<P>
What you need is a "system-property".
Here is how I would go about doing it:
<ul>
<li> No need to modify the asadmin script at all. </li>
<li> ./asadmin set user admin passwordfile /tmp/pass "server.jms-service.host=${${com.memento.localhost}"</li>
<li> This will add this value as expected in domain.xml. </li>
<li> But this is not what you want. </li>
<li> You need something called as a "system property" that is specific to SJS application server. <li>
<li> This is a convenient way of creating a token and replace it at runtime. </li>
<li> Either in the admin GUI or admin CLI, you need to define a system property. For example, the system property in the above case could be defined on CLI as: ./asadmin create-system.properties user admin passwordfile /tmp/pass "com.memento.localhost=the-actual-machine-name"
</li>
Hope this helps.
