Configuration error
Hello!
I'm getting the log4j error message
<error-message>
log4j:WARN No appenders could be found for logger (SomeClass).
log4j:WARN Please initialize the log4j system properly.
</error-message>
This happens in a test case, which has the following main function:
<code-snippet>
import junit.framework.TestSuite;
public class SomeTestSuite extends TestSuite {
...
public static void main(String[] args) {
ConsoleAppender consoleAppender=null;
consoleAppender=new ConsoleAppender();
BasicConfigurator.configure();
Logger.getRootLogger().addAppender(consoleAppender);
Logger.getLogger(SomeClass.class).addAppender(consoleAppender);
junit.swingui.TestRunner.run(SomeTestSuite.class);
}
...
}
</code-snippet>
Why does this error occur despite that fact that I explicitly add
an appender to the Logger of SomeClass?
How can solve this problem?
TIA
Dimitri Pissarenko
PS: I'm using log4j 1.2.8

Most likely candidate is that some where in the Test case code/thread of
execution, that is re-initialising Log4j after your explicit init call,
but before the call to the Logger in question.

I was also thinking that you might consider putting a Log message
immediately following the BasicConfigurator.configure() call. If you
receive this message to the console, then something else is re-initing
Log4j.
BTW, 2 things about your code:
* The BasicConfigurator will automatically add and configure a Console
appender, should be no need to add one yourself.
* Appenders have an activateOptions() method that should be called after
all setters properties have been set, if you create an appender
manually.
