Specifies a system property. A system property defines a common value for a setting at one of these levels, from highest to lowest: domain, server, or config. A value set at a higher level can be overridden at a lower level. Some system properties are predefined; see system-property. You can also create system properties using this element.
The following example shows the use of a predefined system property:
<log-service file="${com.sun.aas.instanceRoot}/logs/server.log"> <module-log-levels admin=INFO .../> </log-service>
The following example shows the creation and use of a system property:
<config name="config1"> ... <http-service> ... <http-listener id="ls1" host="0.0.0.0" port="${ls1-port}"/> ... </http-service> ... <system-property name="ls1-port" value="8080"/> </config>
