Hi Thomas,
the Avalon logger is only provided (and initialized correctly)
automatically to classes when these are Avalon components.
To use an Avalon logger in non-Avalon components, you can do this:
- pass a Logger instance to the class, for example to the constructor.
This is easy if you are calling it from a custom transformer, just use
getLogger(). Then, call the following code before actually using the
logger in that class:
ContainerUtil.enableLogging(this, logger);
(assuming "logger" is the instance of Logger that is passed)
- make the class extend AbstractLogEnabled. That way, you avoid having
to handle the logger instance and can call getLogger() just like you
would in a Cocoon/Avalon component, for example
if (getLogger().isDebugEnabled()) getLogger().debug("hello world");
You can find some examples of this kind of usage within the Lenya code.
