Understanding JSF Process Flow

Question

I am currently studying the internal working of JSF. To aid this I would like to enable TRACE or DEBUG logs of all javax.faces classes. How can I do this? Can such a mechanism be done for other such frameworks too?

Thanks Balusc! This is really helpful and I am just going through your other tutorials. Wonderful! — Shyam Kumar Sundarakumar, May 24 '11 at 10:33

Open the [jdk_install_dir]/jre/lib/logging.properties file, scroll to the bottom and edit the following line near the bottom

java.util.logging.ConsoleHandler.level = INFO

into

java.util.logging.ConsoleHandler.level = ALL

and add the following two lines to the very bottom

javax.faces.level = ALL
com.sun.faces.level = ALL

The first turns all logging for JSF API and the second for the JSF impl, assuming that you're using Mojarra.
