Setting Tomcat System Properies **without** -D on Command Line
Hello,
I would like to be able to configure system properties at Tomcat start-up
*without* adding them to the startup command line, for example you might add
-Dxx.yyy.zzz=123 to the command line to add a system property called
xxx.yyy.zzz with a value of 123. I want something other than this....
I was hoping that there might be a way of loading an additional properties
file in a similar way to catalina.properties but I cannot see this in
documentation. Does this exist? If so can someone point me at the
documentation please.
If this is not the case is there a standard way that would be the
recommended way of writing a custom plugin for Tomcat to do this?
Thank you for your time & effort,
M

The custom way would be to write a startup listener that its only goal
is to load a prop file and promote its properties into the System
environment.
It could look somethng like this:
package cowbell;
import org.apache.catalina.Lifecycle;
import org.apache.catalina.LifecycleEvent;
import org.apache.catalina.LifecycleListener;
public class PropListener implements LifecycleListener {
public void lifecycleEvent(LifecycleEvent event) {
if (Lifecycle.INIT_EVENT.equals(event.getType())) {
try {
System.getProperties().load("fixMe");
} catch(Throwable evil){
}
}
}
}
And in server.xml like this:
<Listener className="cowbell.PropListener " />

take a look at
<init-param> implementation in web.xml

this is doable, just enter all your properties in catalina.properties
first thing tomcat does is ... System.setProperties( - read
catalina.properties - ) ;
so you don't need them on the command line

Tomcat supports use of an admin-supplied setenv.bat or setenv.sh script in which you can specify values for the CATALINA_OPTS environment variable. This will be used on the command line that starts Tomcat. You can write the setenv script to read the values you need from anywhere.

You can do it in exactly the same way as catalina.properties, namely all
lines in catalina.properties are automatically added to the system
properties. Simply add your additional properties to that file.
