CALL FOR: New package org.mmbase.util.logging.java. Since MMBase 1.7 we are using java 1.4. In java 1.4 there is a logging framework (java.util.logging).
I want to add support for this logging framework in a new package
org.mmbase.util.java.
I think there are two things which you may want:
Make MMBase log with java.util.logging.Logger's. This is possible with
the 'Impl' class of this package, which can be configured in log.xml,
and an own property file. So, this wraps java.util.logging.Logger in
org.mmbase.util.logging.Logger.
You have some class which asks for a java.util.logging.Logger where it will log
to, and you
want it to log to the MMBase log. For this, the 'MMBaseLogger' class is meant.
So, this
wraps org.mmbase.util.logging.Logger in java.util.logging.Logger.
So these are the classes I want to include in this package for now. I am
no experienced user in java.util.logging, so obviously bugfixes may
follow. The LoggerWrapper I actually needed for a projectq, the 'Impl' class I
only
tested briefly with the ConsoleHandler of java.util.logging. The general
contract wants to be that org.mmbase.util.logging.java contains classes
related to java.util.logging.
This change is for MMBase 1.8.
Code attached.
