Location of log files
Hello
I could not find a simple solution
to this problem. I deploy a web application (a War file) in
a web server (iplanet) and an ejb application ( an ear file) in
OAS (oracle application server). I want to use log4j in both applications.
The logging works fine. The problem is specifying the location of the log
file.
I use log4j.xml to configure log4j. In there I have to specify the location
of the
log file as absolute path. This creates a problem because we have to edit
log4j.xml
during each deployment of our application to edit the location of the log
file.
I attempted to solve the problem by adding the following code in a utility
class
rootLogger = Logger.getRootLogger();
FileAppender fp = (FileAppender) rootLogger.getAppender("LOGFILE");
String fileName = fp.getFile();
String dir = getOracleRootDir();
if (dir!=null) {
StringBuffer logFilePath = new StringBuffer(dir);
logFilePath.append(File.separator+"log"+File.separator+fileName);
fp.setFile(logFilePath.toString());
fp.activateOptions();
}
which is kind of clumsy. Is there any way of specifying the location of the
log
file without editing log4j.xml (e.g. programmatically or otherwise)
Regards,
Grum

Have you tried using system properties? Log4j performs variable
substitution in XML files as well.
