Notes:

Java Logging (continued)

There are two other values: ALL (log all messages) and NONE (no messages).

A LogRecord is an object that represents a message that should be written to a log. It contains a variety of information, including the message to be printed, the name of the Logger to which it was originally sent, the Level and creation time and date of the message being sent, and the thread ID of the caller.

In ADF, Java logging is particularly useful for tracing Expression Language (EL) evaluation in Faces, although the JDeveloper debugger has been enhanced to enable you to evaluate EL expressions.
