RE: DailyRollingFileAppender

[Pounder, Anthony]

I've looked at the plan for 1.3 and see that there is a section of work
labelled
'Strategy based rollovers' based on the Avalon Logkit.  Have you any idea
when 1.3
may see the light of day?  The Avalon Logkit doesn't seem to mention number
of 
rollovers/compression etc.

Can you give me any feel for the scope of what work is to be included :
e.g. number of rotations to be kept, file compression etc.  Can I aid the
process
by submitting thoughts/ideas/strategies?

Hi,

The install instruction still instruct to set the classpath to -

$LOG4J_HOME/dist/lib/log4j-1.2.jar

instead of 

$LOG4J_HOME/dist/lib/log4j-1.2.7.jar

Which can cause problem to the first time users!

As long as the file's content is in the correct format, by declaring where
the file is located should be the only thing that you need.  There are other
ways to do this but I firgured I would give you one example.

RE: Log4j: Using servlet to init, but how to reload???

[Shapira, Yoav]

Hi,

>

>
>log4j-init-file
>WEB-INF/log4j.config
>
>1

Just keep in mind that the server is not required to keep
load-on-startup servlets in memory.  It may destroy and deallocate them
at anytime, so the destroy() method of your init servlet is NOT a safe
place to do things like LogManager.shutdown().

A ServletContextListener would be a better choice for the above code.

>This works fine, however, any changes made to log4j.config do not take

Did you try PropertyConfigurator.configureAndWatch()?  Then when you
change the file, log4j will pick it up automatically.

In addition, it is easy to write a page that will accept a logger name
and a logging level and set that logger to that level at runtime.  If
you think this approach would be useful for you and need more
information, let us know.

Practical help is most appreciated. In the next few days, I will be 
committing the first strategy based roller over implementation. If you 
would like to help, then subscribe to log4j-dev. This will keep you updated 
with all log4j related CVS commits. You can get the latest code from our 
CVS repository. See http://jakarta.apache.org/site/getinvolved.html and 
http://jakarta.apache.org/site/cvsindex.html for more details.

You can chip in as the code gets developed.

FW: What happens when the logfile is deleted on the server

[MALLER Stijn (BMB)]

Sure,
You have to make a new Appender that extends FileAppender

First add a variable to hold a reference to the logfile

  private File activeLogFile;


Then overwrite the subAppend method to check wether the file still
exists

protected void subAppend(LoggingEvent event) {
if (!activeLogFile.exists()) {
  try {
appendingLog = false;
setFile(fileName, appendingLog, bufferedIO, bufferSize);
  }
  catch (IOException ioe) {
LogLog.error("Could not create file", ioe);
  }
}
super.subAppend(event);
}


And last but not least make sure the reference is always updated when
opening a new file by overriding the setFile method
 
   public synchronized void setFile(String fileName, boolean append,
boolean bufferedIO, int bufferSize)
throws
IOException {
  activeLogFile = new File(fileName);
  super.setFile(fileName, append, bufferedIO, bufferSize);
}


Hope this helps,
Stijn

What do I need to do in log4j.xml to enable debug messages to the console

If in the xml for the console appender I have Threshold="DEBUG" I get my

get the
JBoss debug messages.

RE: InvalidClassException

[Cakalic, James]

Let me preface this by saying that I've used serialization lots of times
on objects passed between an application server and Java client (using
RMI/IIOP) when those objects contained private static Logger (or
Category) fields. So I'm sure it can be done.

Did you deploy the new class to both the server and the RMI client? Most
of the time this is the problem. The class definition has apparently
changed by the addition of the static field. According to the
Serialization Spec, "If not specified by the class, the
value [serialVersionUID] returned is a hash computed from the class's
name, interfaces, methods, and fields using the Secure Hash Algorithm
(SHA) as defined by the National Institute of Standards." Although
private static fields are _supposed_ to be ignored when computing the
hash, this may be a defect with either the server or client runtime jvm.
Also, the class initialization method, if it exists, _is_ part of the
hash. So, and I'm going out on a limb here, if this is the first static
field or the first one with a declared initializer, a  method
may have been added to the class. Also, if you've made any other code
changes in concert with adding the static field these may be changing
the UID of the class.

Were both the server class and client class compiled using the same
compiler? Compilers oftimes 'synthesize' various data members. Each
compiler does this differently. That means that the same class compiled
by two different compilers could have different values for
serialVersionUID. This was a real problem for my team using VisualAge
for Java. There was the IDE-internal compiler, a different compiler that
was used by the IDE for export, the JDK javac compiler, and then we were
using a version of jikes to speed up the builds. Each of these produced
differing class definitions.

Have you tried explicitly setting the serialVersionUID of the class?
This is a private static final long field. This prevents the hash
calculation as I indicated above. You can use the serialver utility (try
'serialver -show') to determine an appropriate value to use. Also, you
can use this utility to see whether the serialVersionUID of the class
seen by the server and the class seen by the RMI client have the same
computed UID. See the JDK docs and Serialization Spec for more details
on serialver.

enabling ConsoleAppender DEBUG for specific Logger via log4j.xml

[Glen Cordrey]

What do I need to do in log4j.xml to enable debug messages to the console appender
for a Logger I get via org.jboss.logging.Logger.getLogger( "MyLogger" )?
If in the xml for the console appender I have Threshold="DEBUG" I get my debug messages
but am also swamped by JBoss housekeeping debug messages, so I want to not get the
JBoss debug messages.

Re: InvalidClassException

[Ceki Gülcü]

That is not it. Static variables are not serialized. The problem David is 
facing is not log4j related rather it is what the errors says: "Local class 
not compatible". David is probably working with two incompatible version of 
the same class.
