Hello there,
I am using an init servlet to load my log4j.properties file during app start
up...
public class Log4jInitServlet extends HttpServlet {
public void init() throws ServletException {
Properties props = new Properties();
try {
props.load(this.getClass().getClassLoader().getResourceAsStream(
"/log4j.properties"));
} catch (IOException e) {
e.printStackTrace();
}
}
}
The log4j.properties file:
log4j.rootLogger=WARN, stdout
log4j.logger.acme.myapp=DEBUG
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n
Question(s):
(1)
Let's say I want to use a file appender for logging different parts of
the app's behavior, do I need to create a different properties file?
(2) If not, how would I integrate that with the properties file above?
(3) Is there a way I set the DEBUG warning to just log to the Console and the
LOG warning to just log to specific files (which I specify)?
(4) What if I wanted two separate log files generated for the file appender?
(e.g. one being for cars.log and another one being planes.log)
(5) Do I have to create a different init servlet and different properties file?
Happy programming,
