configuring log4j [message #897555] Tue, 24 July 2012 09:31 Go to next message
Eclipse UserFriend
Hi,

I'm taking the risk of asking a stupid question, but I just can't get it...

I have written a log4j fragment with a log4j.properties and it works fine with a launch configuration where org.eclipse.xtext.logging is not present. But when I install my plugin as an user, how do I make sure my configuration is the one that gets used? The xtext.logging fragment is already installed with the SDK.

Should I load the properties file and use it to configure log4j myself, instead of relying on it finding the right config file?

In a related topic, if I want to use an EclipseLogAppender like xtext.logging does, I have to implement another one in my code, right?

best regards,
Vlad

The only chance is to make sure that xtext.logging is not on the
classpath or that your fragment has a higher precedence. I'm not sure
about the latter ...

Ok, thanks! I will then configure log4j manually in my plugin activator.

Hi Vlad,

having wasted some hours trying to get log4j running in an Eclipse application I found out about the Xtext plugin as well. By debugging, I found the following solution:
In your fragment, use a log4j.xml instead of a log4j.properties.
The log4j framework tries to find the .xml before the .properties.

This will only work until the Xtext team decides to move to .xml. I have not found a way to specify fragment precedence yet.

Thanks Andreas,

Right now I do the configuration manually, which has also the advantage that I can watch for a local configuration file and reload it if it changes. More exactly, if I want to watch it anyway, doing the initial configuration manually is not a big deal.

regards,
Vlad
