Different logger objects

[Ex...@nokia.com]

Hi all,

Is it possible to define two or more different logger objects in one Java Program? I am trying to create an own logger for each created object in the program, but using the instance Logger.getLogger(name) makes this no possible because when I create the second instance I "loose" the reference to the first one, probably because using static variables that changes and each object is using. Don't know how to do...

I have tested if it's possible with the following example code:

	this.logger1 = Logger.getLogger(MyClass.class.getName()+name1);
	PropertyConfigurator.configure("log4j.properties");
	logger1.info("- Logging initialized --");
	
	this.logger2 = Logger.getLogger(ApiTesterTool.class.getName()+name2);
	PropertyConfigurator.configure("log4j.properties");
	logger2.info("- Logging initialized --");
	
	// Till here the code works perfectly, the first logging information is written in one file and the other in the other one
	// Next line pretends to write again in logger1
	
	logger1.info("This line must be written in file defined by logger1 but is written in logger2 !!!!!!!!");

Please help a poor Java programmer ;-)

Jaume

You only need to call PropertyConfigure.configure() once per thread.

This could be the source of your problem.
