newbie questions

[Will Lee]

Hello,
I just started learning GWT and gwt-log, and have some questions.
I used Log4j before, and it's great that gwt-log has similar feel to
it.

I was wondering how to configure which class to show logging
selectively.
Say that I put logging statements to both class A and B.
Is there a way to make the logging visible for only class A?
Is this something that I can configure in gwt.xml?
or do I need to add .properties file (similar to log4j.properties)?

Thanks for your time!

Thanks for quick reply, but I'm not quite sure about the usage of the
category.

What I am trying to achieve is, for example,
if ClassA has logging statements
Log.debug("construct A")
Log.debug("hello A")

and classB has
Log.debug("construct B")
Log.debug("hello B")

I get logging output like this:
construct A
construct B
hello A
hello B

now, I want to see only logging outputs of classA like this:
construct A
hello A

If I were using Log4j, I would set log4j.properties
log4j.logger.ClassA=debug
log4j.logger.ClassB=error

How can I achieve the similar results with gwt-log?

You would log more like this:

    Log.debug("com.foo.myproject.mycategory", "2 + 2 = 5, for large values of two", exception);
