Thanks for your quick response. For the most part, I really like the log4j
library. And, when I run the program with -Dlog4j.configuration=log4j.xml
it does indeed work. (I was able to do this prior to the email.) However,
rather than doing the log4j default initialization with
-Dlog4j.configuration, I'd like to be able to specify the file to the
program and call the PropertyConfigurator.configure() passing it the file
name -- a system that works fine with the old style configuration files.
Here's the code. Can I pass an XML file to
PropertyConfigurator.configure()? Do you see something else I'm doing
wrong?
Thanks again,
Mark
import org.apache.log4j.*;
import java.io.File;
public class test {
static Category logger = Category.getInstance(test);
public test(String x) {
this();
System.out.println(x: + x);
}
public test() {
System.out.println(test());
}
public static void main(String args[]) {
// Initialize Log4J.
String logConfig = null;
String log4jConfigFile =
System.getProperty(log4jConfigFile, log4j.config);
if (new File(log4jConfigFile).exists()) {
PropertyConfigurator.configure(log4jConfigFile);
-- HERE'S THE CALL TO CONFIGURE
}
else {
// No configuration file. Set it up manually.
PatternLayout pl = new PatternLayout(%d [%t] %-5p
%c - %m%n);
ConsoleAppender ca = new ConsoleAppender(pl);
BasicConfigurator.configure(ca);
logger.setPriority(org.apache.log4j.Priority.DEBUG);
logger.warn(Log4j configuration file \ +
log4jConfigFile + \ not found. Using BasicConfigurator.);
}
logger.debug(main);
System.out.println(hello);
test t = new test(stuff);
System.out.println(Done.);
}
}

The property name you are looking for is log4j.configuration.
Invoke your program as
java -classpath `local_jars` -Dlog4j.configuration=log4j.xml -Dlog4j.debug
test
HTH, Ceki
ps: Your XML file was never read.

I've dorked around all day trying to get an xml configuration file working.
It complains about not finding a root element. The documentation on the
XML
configuration file is weak at best. (Only a few examples, all the same.)
I want to send output to stdout and to a log file (simple enough).
Below is what I get. Any help would be greatly appreciated!
