Hello every body:
I am having some difficulties working with log4j, and I need some help
from some one.
I am writing a client/server application, in some way it can be compared
with a chat client, where two or more users connect to the server
through an applet.
Now the applets uses classes from packages I wrote. The classes logges
messages to no where (no logger is configured in them) I left the
configuration for the main class, so that I can reuse those classes
elsewhere. I am using a simple appender that I wrote, to display the
logs in a JFrame.
The problem is I am getting the logs from each applet displayed in it's
own log JFrame and in the other one!!
I am testing this on my machine, now both chat programs (applets)
connect to the server. The first one logs the messages to both Frames !!
And the second one does the same.
At the begining of each applet I used this:
//********************************************
logger = Logger.getLogger(this.getClass());
Logger.getRootLogger().addAppender(new FrameAppender(this,"Controller
logs"));
logger.setLevel(Level.ALL);
BasicConfigurator.configure();
//********************************************
from what I understand, Logger.getRootLogger() is a static method,
therefore the logger returned by it ( Logger.getRootLogger() ) is
static, but static means for each JVM. In other words, both applets run
in a separate JVMs, and there should be nothing shared !!!
Now, what ever was the reason, how do I get around this ??? Let's say My
main class is called Chat.java , and it uses another class CustomSocket.java
What i would do in CustomSocket.java, is instantiate an object of Logger
through Logger.getLogger(this.getClass()), and logs my messages
normally. Then the application that uses CustomSocket has to configure
the logger (apender, Level ,....etc). How do I achive this. Please note
that I am only newbie, and I am not looking to use configuration files.
Just doing very basic configuration.
If you need any more info about this problem, just please let me know, I
've included what I think is relevant.
Thank you.
