I'm using JBoss 6.1, how to set system properties in JBoss?
You have two approaches to do:
Approach 1: Edit standalone.xml in [JBOSS_HOME]
Approach 2: Log into JBoss Admin console to do configuration
Step 1: Click Profile
Step 2: Click System Properties
Step 3: Click Add button
Step 4: Fill in Name and Value, then click Save button
No matter which approach you utilize, remember to RESTART JBoss after configuration.
