how does jboss find jboss-log4j.xml

[ramon_lmj]

As we know, in conf/jboss-service.xml, Log4jService is configured with specified url resource:jboss-log4j.xml. This is not a URL with file protocol.
My question is what is resource protocol. And how can jboss find the actual jboss-log4j.xml file under conf folder.
I tried
URL configURL = new URL("resource:jboss-log4j.xml");
but the following exception is thrown.
Exception in thread "main" java.net.MalformedURLException: unknown protocol: resource
at java.net.URL.(Unknown Source)
at java.net.URL.(Unknown Source)
at java.net.URL.(Unknown Source)

could someone give me some tips? thanks.

JBoss registers a custom protocol handler org.jboss.net.protocol.resource.Handler http://anonsvn.jboss.org/repos/common/common-core/trunk/src/main/java/org/jboss/net/protocol/resource/Handler.java to handle the resource: URLs.
