log4j xml configuration
I am having problems getting log4j to configure from an XML file.
When I use the xml file shown below, i get the following warning in
java (1.4.1_02). Note: When I use a non-XML properties file it works
just fine.
log4j:WARN No appenders could be found for logger
(edu.jhuapl.latency.GNCSTlatencylog4j).
log4j:WARN Please initialize the log4j system properly.
Any ideas? Thanks in advance.
Here is the xml file

You have to invoke the DOMConfigurator.configure method instead
of the PropertyConfigurator one.
URL log4jURL = null;
try {
log4jURL = getServletContext().getResource("/" +
configPath);
} catch (MalformedURLException murle) {
//ignore...we check for null later
}
if (log4jURL != null) {
DOMConfigurator.configure(log4jURL);
}

OK, I added a file named log4j.xml to a directory in the classpath
and this works wonderfully.
The next question is I want to use the PropertyConfigurator to load a
named config file. When I pass the PropertyConfigurator a non-xml
file it works, but if I pass it an xml file it does not. Is there
something I need to do in the PropertConfigurator to get it to load
an XML file
Here is the code i use to pass the filename to the
PropertyConfigurator
String userDir = System.getProperty("user.dir","test");
String fileSeparator = System.getProperty("file.separator");
String filename = userDir +
fileSeparator +
"config" +
fileSeparator +
"Sync_GNCST_Latency_config";
// use the Property Configurator to configure log file.
PropertyConfigurator.configure(filename);

Actually, it's log4j.xml first and log4j.properties second. Of course, this
does not help in hunting down the problem.

Try removing all appenders except for the console appender from the <root>
logger and see it works. Reducing the extraneous variables will help
pinpoint the problem more efficiently. Also, I assume you had put
log4j.properties in the classpath and let log4j load it automatically. I
imagine you did the same for log4j.xml. I think Log4j loads properties
files preferentially to XML files (I could be wrong here). Given that, it
is possible that there were no other log4j.properties files in the
classpath other than yours, but there may have been another log4j.xml file
in the classpath that might be overriding yours. That's just a shot in the
dark as to why it worked with the properties file and not the XML file.
BTW, you should use <level> rather than <priority>.
