Log4j Properties not loaded

[M Mehta]

I am working on a web application and trying to use log4j logging in it. But I am not able to load the log.properties file.
I am using PropertyConfigurator.configure("log.properties"); where log.properties is in classpath. But it gives me in following exception:

However if I try to use the same thing from a stand alone application with main , it works fine.
Can anyone help me know the issue?

Thanks,
Me

PropertyConfigurator.configure(String) uses local files to load from. Try using Class.getResource or ClassLoader.getResource in combination with PropertyConfigurator.configure(URL):

PropertyConfigurator.configure(getClass().getResource("/log.properties"));

The actual path to the resource may need to be a little different, but this would be the basic idea.

[Raj Kamal]

Hi,

The first line in the log says

ERROR Could not read configuration file [log.properties].

Since you are working on a web app the properties has to be in the WEB-INF/classes folder of your web application.

Cheers,
Raj.

[M Mehta]

yeah, I put it in the WEB-INF/classes, but still getting the same error.

Have you tried my advice already?
