AW: AW: using log4J with Struts

[Rainer Alföldi]

Hi Azeem,

 

I think I attached all needed files. I just renamed them and deleted everthing not needed for log4j.

 

- Startup-mailinglist.java:

Contains public void init(ServletConfig config) which is called during servlet initialisation. This method calls private void initLog4J( Properties initProps ).

 

- init-mailinglist.conf:

This is the properties file used by Startup-javaand contains all parameter used to init log4j. (Basically path for log4j config file and time intervall for the reload option of log4j.)

 

- log-config-mailinglist.xml:

this is the xml-config file for log4j. here you define what packages should be logging where to and at what logging level. This file is used in Startup.java at "DOMConfigurator.configureAndWatch( url, reloadTime );". Check the log4j documentation if you need more support on this.

 

Moving the application transparently? The appender files are still hardcoded. If we ever have to much time during this project, we´ll fix that up... ;-)). Everthing else is independent of absolute paths.

 

 

Greeting

 

Rainer

You forgot to attach the routines and log4 J config file. I am new to both Struts and Log4j.So what it is coming down to is you define init params in one of the routines you are talking here and then reference them in web.xml, so it gets registered with controller servlet. Could you send a sample of web.xml with log4J categories registered in it along with some init routines.

What would be the best way of passing config file for log4J to PropertyConfigurator(config), in cases where you are developing your application in one environment and then want to move your application transparently to a differently env without affecting passing of config file location(e.g moving from Windows to Unix) 

Thanks

Azeem
