Subject Re: Indyo problem - log4j:WARN No appenders could be found for logger
Date Mon, 17 Feb 2003 22:04:50 GMT
This seems to be a log4j problem. You may see the link below:

------------------------
http://jakarta.apache.org/log4j/docs/TROUBLESHOOT.html
log4j tells me to initialize properly.
Logging output is written to a target by using an appender. If no appenders
are attached to a category nor to any of its ancestors, you will get the
following message when trying to log:

log4j: No appenders could be found for category (some.category.name).
log4j: Please initialize the log4j system properly.
Log4j does not have a default logging target. It is the user's
responsibility to ensure that all categories can inherit an appender. This
can be easily achieved by attaching an appender to the root category.

-------------------------

Is it possible to use Indyo as it is? Do we have to do some further
configuration on log4j? If it is easy to do that, how can I do that?

Thanks
Harun.
