Category VS logger tags in jboss-log4j.xml

Question

What should we use in jboss-log4j.xml in order to turn on/off traces for our product - "category" or "logger" tag?

By default JBoss uses "category" in jboss-log4j.xml.
But as far as I know "category" is deprecated and "logger" should be used instead.
Why JBoss uses deprecated "category" tag in a new product?

Answer 1

Habit, I suspect. I still to use category also. It behaves exactly the same as logger, there really is no difference.

Looking at the javadoc, the Category class is now deprecated in favor of Logger. In the configuration, I would expect both would be supported. – Oran

it is bad habit to continue to use depreciated features. – Afterburning

Answer 2

category in the log4j.xml (not limited to jboss-log4j.xml) is common practice and its not deprecated. What got deprecated is the Category Class as in usage of Category in code like,

Category category = Category.getInstance('something');

In log4j.xml, both category and logger can be used. Probably the newer code will have the logger in log4j.xml. Old way is category.

Okay, but what about the difference between them? And also category seems to have level and priority as acceptable properties: what is the difference between those? – Relique
