Thanks ..
But will you -remove- DOMConfigurator?
Yes! DOMConfigurator will eventually be reduced to
/**
* @deprecated Use JoranConfigurator instead.
*/
class DOMConfigurator extends JoranConfigurator {
}to provide backward compatibility and then it will be simply removed.
I mean, it is -just- a simple setter, and a very natural one that is. If you're about to deprecate it, why not just add it, and deprecate it in the same go - it is really "a missing feature".
The code in DOMConfigurator will not survive in 1.3beta.
The point is that the DOMConfigurator already do perform -general- variable substitution, but since the "props" reference in DOMConfigurator is highly null (there are only -one- reference to it ever, that is when it's passed to the substituter!), all substitutions are done using only System.getProperty().
I know. I just did not want to waste time implementing it given the bleak future awaiting DOMConfigurator.
Btw: the javadocs there says that it first tries system props, then the supplied props - this is not true reading the code.
Yes. That is the indented behavior.
The code is even cooler than I knew; there is recursive substitution!
The Joran stuff: shouldn't this also have this -amazing- feature that property-substituion really is from start of? It is really magic - it solved all my problems! I earlier had a script that reg-exped through the log4j.xml file for some stupid delimiter, before starting tomcat. Now, when I found this (undocumented?) feature, I only use the -D options to the java-invoker!
The idea is to be able to use either -D options (system properties) or a property file as described in the javadocs.
Endre.
