Deployment Descriptors & System Properties Subsitution

[jiwils]

System properties substitution is allowed in jboss-service.xml deployment descriptors using ${system property name} syntax. Is this true for all deployment descriptor files (including the ones specified by the various J2EE standards)?

Amazingly, it does work in most all the XML files. I wouldn't recommend using it in your web.xml, but you certainly could if you wanted to.

Hmmm,

did you actually test this in any of the standard deployment descriptors (application.xml, ejb-jar.xml, web.xml)?

I just tried it:

ejb-jar.xml

 <env-entry>
 <env-entry-name>testEnvEntry</env-entry-name>
 <env-entry-type>java.lang.String</env-entry-type>
 <env-entry-value>${test.replaceme}</env-entry-value>
 </env-entry>

bean

System.out.println("!!! " + System.getProperty("test.replaceme"));
try
{
 InitialContext ic = new InitialContext();
 String test = (String)ic.lookup("java:comp/env/testEnvEntry");
 System.out.println("!!! env entry = " + test);
}
catch(NamingException ne)
{
 ne.printStackTrace();
}

run.bat

set JAVA_OPTS=%JAVA_OPTS% -Dtest.replaceme=REPLACED_VALUE

output

15:36:39,171 INFO [STDOUT] !!! REPLACED_VALUE
15:36:39,171 INFO [STDOUT] !!! env entry = ${test.replaceme}

The system property is set.
The reference to it in the deployment descriptor does not work.

Am i missing something?
Have others seen it work elswhere?
