JSF2 logs with tomcat

Question

I\'m having a project using JSF2 (2.1.2), Richfaces4 (4.0.0.Final) on tomcat6 (6.0.28). In order to manage portability between Tomcat and WebSphere7 for my EARs, I have the

Answer 1

Two facts:

• JSF uses java.util.logging API which is to be configured by a logging.properties file in the root of the runtime classpath.
• The logging.properties file of the currently(!) running runtime environment (JRE) will be used.

If you're running Tomcat from inside an IDE like Eclipse, then Tomcat's own logging.properties won't be used. The one in JDK/JRE/lib will be used where "JDK" is the JDK install folder such as jdk1.6.0_23. If you'd like to explicitly specify the location of the logging.properties file, then you would need to set a VM argument:

-Djava.util.logging.config.file=/path/to/tomcat/logging.properties 

Regardless of the logging file used, in order to enable Mojarra logging, you need to open the logging.properties template file in question, 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

so that the global console level is set to ALL instead of INFO. Otherwise lower levels than INFO just won't be logged at all.

Finally add the following two lines to the very bottom of the file

javax.faces.level = ALL
com.sun.faces.level = ALL
javax.enterprise.resource.webcontainer.jsf.level = ALL

The first turns on all JSF API logging, the second turns on all JSF impl (Mojarra) logging, and the third turns on all JSF Java EE logging.
