Changing log level on Logger

Im trying to figure out how the Logger works but ran into some problems.
I'm trying to use the entering and exiting methods. From the API they are said to be of FINER-level. So in order to have them displayed I reckoned all I'd have to do is call myLogger.setLevel(Level.FINER). Unfortunately this didn't make my entering and exiting messages show.
What am I doing wrong?

Hi Jim,

I'm betting on 2 things:
  • You are using the ConsoleHandler

  • The default level for the ConsileHandler is Level.INFO

  • You are setting the log level on the Logger instance

  • Setting the log level on the logger only tells the logger what level of messages are to be passed to the handler. It doesn't change anything on the handler.

    So, if I am right, your logger is correctly set such that it sends messages to the handler, however the handler then ignores them.

    Simple fix: set the level on the handler as well:
    With the output:

    Regards, Andrew

    You were absolutely right. Changing level on the assosiated handlers aswell solved my problem. Thanks Andrew.
