If we upgraded log4j-zeroconf to use JmDNS 2.0, that would effectively mandate it to also require 1.6 (currently you can get it to work on JRE 1.2). I have just played around with some old code which previously worked with Chainsaw Zeroconf (guaranteed jmdns 1.0), and it did not show up in the zeroconf window when starting Chainsaw over webstart (which reports Zeroconf to be available - perhaps it uses Bonjour 1.0.6?) so I've probably done something wrong. I am aware that this is is not the same issue as the one reported in this thread, but I would really like to ask if you could create a simple "run me to test zeroconf"-application which could also be run over webstart so it is very simple to run these two applications next to each other and see that stuff works?

Re: HOw to replace the system.out.println
MY POI skrev den 02-09-2008 14:34:
Thanks a lot..but here we are having hundreads of classes..
in this case any solution is there
This might help you getting started:
helpers/FooBar.java
=
package helpers;
public class FooBar {
public static void main(String[] args) {
System.out.println("Hello World");
System.out.println("Hello World");
org.slf4j.LoggerFactory.getLogger(Me.callerClass()).info("Hello
World");
org.slf4j.LoggerFactory.getLogger(Me.callerClass()).info("Hello
World");
}
}
=
helpers/Me.java
package helpers;
public class Me {
public static String callerClass() {
StackTraceElement[] stackTrace =
Thread.currentThread().getStackTrace();
int level = 0;
while
(stackTrace[level].getClassName().equals(Me.class.getCanonicalName()) ==
false) {
level = level + 1;
}
// level is now *HERE*
StackTraceElement element = stackTrace[level + 1];
return element.getClassName();
}
}
When FooBar is run, it generates this output:
===
Hello World
Hello World
0 INFO helpers.FooBar Hello World
0 INFO helpers.FooBar Hello World
===
Hence you should be able to globally replace instances of
"System.out.println" / System.err.println with
"org.slf4j.LoggerFactory.getLogger(helpers.Me.callerClass()).info" in
your text files and have something working.
This requires Java 5 and is slower than actually creating a static
logger instance but allows you to postpone the actual nitty gritty stuff
for later.

Re: Using independent logs at runtime
JethroXT skrev den 27-07-2008 19:16:
Hi,
I have a problem that maybe someone could solve:
I have a network consisting of several nodes that all have to log data
independently.
I don't know the exact number of nodes before runtime, so Loggers (or
appenders) have
to be created at runtime.
Is this at program start time or dynamically changing while running?
If it is at program start time you can set a system property which can
then be expanded in the log4j.properties file. From
PropertyConfigurator javadoc
"All option /values/ admit variable substitution. The syntax of variable
substitution is similar to that of Unix shells. The string between an
opening *"${"* and closing *"}"* is interpreted as a key. The value of
the substituted variable can be defined as a system property or in the
configuration file itself. The value of the key is first searched in the
system properties, and if not found there, it is then searched in the
configuration file being parsed. The corresponding value replaces the
${variableName} sequence. For example, if |java.home| system property is
set to |/home/xyz|, then every occurrence of the sequence |${java.home}|
will be interpreted as |/home/xyz|. "
Is this what you need?

No. The logger frameworks do not do magic to deduce where logging should go. If you want for classes called to use a specific logger, you must pass it as an argument like all values you want to use. Instead I got an log4j warning: log4j:WARN No appenders could be found for logger (curam.tools.upgradehelper.util.SQLStatements). You are most likely using a logger variable in SQLStatements which has been defined at the top of that class referring to SQLStatments.class. This does not allow log4j to distinguish between the two cases you have. I have the same problem in a project where it is two threads logging in the same file. I have not yet found a good solution. During my testing I have defined a root logger as well, but it does not do what I want. All the expected lines are present in both files but the files are populated with the log from the same class. This say that you want all messages at info level or higher to go to both the taskRedirection appender AND the addQuestionSequenceOrder appender. -- Thorbjørn - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: additivity attribute for logger does not diffrently for root and user-defined logger.

This sounds like your configuration file is not picked up. Try running with -Dlog4j.debug=true to see what is happening. What is the meaning of the attribute "additivity" for each logger? From http://logging.apache.org/log4j/1.2/manual.html "*Appender Additivity* The output of a log statement of logger /C/ will go to all the appenders in /C/ and its ancestors. This is the meaning of the term "appender additivity". However, if an ancestor of logger /C/, say /P/, has the additivity flag set to |false|, then /C/'s output will be directed to all the appenders in /C/ and it's ancestors upto and including /P/ but not the appenders in any of the ancestors of /P/. Loggers have their additivity flag set to |true| by default.

Is there a way to make Eclipse recognize log4j messages in its console buffer and hyperlink to the statement that created it?
We use Eclipse for development and I like the way that stacktraces are shown and linked to the underlying source, so I was pondering whether similar functionality is possible for the numerous debug messages we have? I looked at the Ganymede plugin, but it requires an alternate log4j configuration, which I would prefer not to have. Is there other approaches for this? Or should I look into conditional configuration files? -- Thorbjoern Ravn Andersen "...plus...Tubular Bells!" - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
