JLogger is a pre JDK
1.4 implementation of the Logging API's. This means that you
can write your code to the JDK1.4 standards without future migration
worries. JLogger allows you to log to the console, a file or
a socket at the same time. You can customise Formatting and
add your own Loggers. And it's all FREE.
JLogger also includes this
Cool Swing Console. You can see all the current Loggers,
and change their level at run-time. You can also see all
the Log Records, with the SEVERE ones listed separately.
In addition clicking on a Log
Record will display the records details in a new Frame.
Just the job to monitor those J2EE bugs.
