Jboss Server Not Loading Java Environment Properties

Question

I am trying to load a properties file in a web application using the following code in Java.

InputStream in = ContextEventListener.class.getResourceAsStream(resourceConstVal);
Properties config = new Properties();
config.load(in);

When this application runs on tomcat server; all the properties specified in the properties file get exported as system variables and are accessible via the following code

System.getProperty("TEMP")

`
However, when the same application ran on Jboss server; the properties had to be explicitly exported by

Set<Object> keySet = config.keySet();
for (Iterator iterator = keySet.iterator(); iterator.hasNext();) {
String strVal = (String) iterator.next();
System.setProperty(strVal, config.getProperty(strVal));
}

Using JDK 1.6 , Tomcat 7.0 , Jboss AS 6.1.

Content of Property File
CONTENT_DIR=XXXXXX
RESPONSE_FILE_NM=YYYYYYYY
REQUEST_INT_FILE_NM=ZZZZZZZ

Wondering why behavior varies in different application server.

That's becouse Jboss puts the .properties file inside jars on the classpath and can not be edited sometime after the deploy. Here is a workaround https://developer.jboss.org/wiki/HowToPutAnExternalFileInTheClasspath

To load properties file, it only needs read permission which is present because the Properties object loads fine from input stream. It's the individual properties that are not exported. – Allzhere Sep 29 '15 at 18:15
Your link appears to be broken. – roflcopter1101 May 20 '22 at 13:27
