How to add External PropertySource file to jetty 9 jetty.xml ?
i use spring annotation and External PropertySource file

#PropertySource(name = "arm", value = "${propertySource}")
})
public class SecurityConfig extends WebSecurityConfigurerAdapter {
when I run the application through maven I use paramentr like propertySource:

Its work perfect jetty start with /etc/jetty/arm.properties config params.
How to add -DpropertySource=/etc/jetty/arm.properties like a parametn to start jetty ? hoe to configurable jetty.xml ?
I read docs
http://www.eclipse.org/jetty/documentation/current/jetty-xml-usage.html
and add string to jetty.xml :
<SystemProperty name="propertySource" default="file:/etc/jetty/arm.properties"/>
but this does not work, and jetty fail.

Answer 1

The use of <SystemProperty> is to evaluate a named system property and use it in an XML file as a value for whatever thing you are attempting to configure.
There's 2 ways you can accomplish this using the jetty-distribution.
1: Simply use the Java JVM command line to add the property
$ cd /path/to/mybase
$ java -DpropertySource=file:/etc/jetty/arm.properties -jar /path/to/jetty-dist/start.jar
2: Allow the ${jetty.base} to manage the Java JVM properties
In your ${jetty.base} add the following 2 lines to your start.ini
--exec
-DpropertySource=file:/etc/jetty/arm.properties
Then you can just run Jetty normally ...
$ cd /path/to/mybase
$ java -jar /path/to/jetty-dist/start.jar
Bonus: Alternate technique
Since this is Spring, you could probably switch to using a classloader resource instead.
Run this command to enable resources classpath
$ cd /path/to/mybase
$ java -jar /path/to/jetty-dist/start.jar --add-to-start=resources
Then put your properties file in the new ${jetty.base}/resources
Lastly, reference your PropertySources via the Spring classloader resource reference instead.

In your ${jetty.base} add the following 2 lines to your start.ini
--exec
-DpropertySource=file:/etc/jetty/arm.properties
#service jetty9 start

solution 2
add to start.ini line --add-to-start=resourcesc
# sudo service jetty9 start
[warn] Starting Jetty 9 Servlet Engine: jetty9[....] /var/run/jetty9.pid exists, but jetty was not running. Ignoring /var/run/jetty9.pid ... (warning).
failed!
Where can I see the log ?
