Chainsaw and VFS XML Layout

[Jeff Longland]

I was just wondering if there's a VFS receiver that supports XMLLayout?

Thanks!

From a previous time the question was asked:


On Jan 11, 2007, at 4:27 PM, Curt Arnold wrote:


log4j doesn't actually produce an XML document since an XML  
document can only have one element.  log4j produces an XML parsed  
entity (in this case a sequence of elements) that can be referenced  
in an XML document and it is assumed that the containing document  
would declare the namespace prefix.  To process the output of log4j  
by XSLT, you would need to create a small XML document that  
includes the log file and then process the XML document using XSLT.


Your XML document would look like:

Question comes up enough that there should be a FAQ on it and check  
that the documentation mentions it.

Re: Using XMLLayout..

[James Stauffer]

Since the file is continuously changed it wouldn't be possible to have
a root element unless it is added as it is rolled.

Hi,



As a part of our J2EE application, we need to build a custom Layout for

The custom layout need not to conform to any DTD, but, needs to be a
well-formed XML with the root element.

I am using XPath expression on the XML string to get the proper output.



Right now, I have extended the Layout class to generate the output using
brute StringBuffer append method.

When I am trying to transform this file (which is not a well-formed
XML), the transformer complains that it is missing the root element.

Is it a better idea to tweak the XMLLayout to fit-in the custom content?



Here is a sample of the content that is in the log file:

myHostResponse

myHost1FAIL

myHost2Unknown



If I can get this with a root element, the transformer works fine.





myHostResponse

myHost1FAIL

myHost2Unknown





I appreciate any help on this.

RE: Multiple logging files

Ok,
after having set the new system property to change dynamically of
location for the logs,
I reload the config,

System.setProperty("log.name","idRequest+".log");
DOMConfigurator.configure(AppConfigManager.PATH_TO_LOGS+"log4j.xml"); 


Thank u for your support:-)

Ok,

I have set the system property before to initializing log4j

(just as test :
System.setProperty("log.name","temp.log");
DOMConfigurator.configure(PATH_TO_LOGS+"log4j.xml");

Then I change dynamically the system property to change the directory in
which the logs need to be stored :
System.setProperty("log.name",idRequest+".log");

But the logs keeps getting stored in temp.log

3. Both the system property and any needed directories need to be set
before log4j is configured.  I created an appender that can create
directories as needed and it is at
http://stauffer.james.googlepages.com/DateFormatFileAppender.java

4. In your code you don't refer to a special appender, you refer to
special loggers.
i.e
Logger logger = Logger.getLogger(getClass().getName());
Logger specialLogger = Logger.getLogger("special." +
getClass().getName());

Hi,

Yes, perhaps there are reasons to change it, but then help me understand how
to configure log4j in the following scenario.

We provide a log4.xml within our app's jar so that our application logs
messages during startup (say to file1 and console). We also let the users
specify a separate (external to our jars) log4j xml file to configure how
the app should log messages after the startup phase (say file2 and console).

With 1.2, this could be done by attaching the corresponding 2 appenders to
the  element in each of the config files. How would I achieve the same
behavior in 1.3? At this point, both file1 and file2 are growing, and every
message is showing twice on the console.

Thank you

Hello Jake et al,

The complete log4j manual is correct as far as log4j 1.0, 1.1, 1.2 are
concerned. However, in log4j 1.3 the behavior was changed because:

1) it is not what a user would expect without reading the docs (surprise
element)
2) very few people seemed to take advantage of the "pre 1.3" behaviour**

** The "pre 1.3" behavior was intended to support partial config files

The different behaviors should be transparent to the user as long as she
does not do partial configs.

I hope this helps,

This should do what you want:
1. Switch to XML config.
2. Define your main appender and special appender
3. Use a system property for the name of the file in the special
appender.
4. Make sure you have your loggers setup so logs from the special part
of your code go to the special appender.

For the System property issue I tried this :

  
  
  
  
   
  
  

And in my Java applciation I execute this line before I need to log in
the special appender :

System.setProperty("log.name",idRequest+".log");

[2/28/07 12:16:32:297 CET] 3e89f5a2 SystemErr R log4j:ERROR
setFile(null,true) call failed.
[2/28/07 12:16:32:297 CET] 3e89f5a2 SystemErr R
java.io.FileNotFoundException: C:\UserTemp\matthew016 (Access is denied)

Though something like this  works.

I tried also a simple thing :
If I do this :


[2/28/07 12:15:17:669 CET] 3e8d3584 SystemErr R log4j:ERROR
setFile(null,true) call failed.
[2/28/07 12:15:17:669 CET] 3e8d3584 SystemErr R
java.io.FileNotFoundException: C:\UserTemp\matthew016\updates\test.log
(The system cannot find the path specified)
 
It gives me the same error, because it cannot find the directory
"updates" under dir "matthew016".
Though I create this dir dynamically in my application *before* any logs
need to be stored trhough the appender specified output.

Yes exactly  :-) Thank u very much,
I realized I did this all wrong.

I have read the Log4J tutorial,

I did the points 1 & 2, but for I have some difficulties on how to
implement point 3 & 4

I switched this to XML :

  
   
   
   
   
   
  
  
  
  
  
  
   
  
  
  
  
   
  
  
  




  


*  In my Java class I don't know how I can specify which appender I
should use,
   Or maybe I can specify the logger in the log4j.xml file ?

*  I don't knwo how to use the system property,
   In the program I suppose I just need to do something like this :
System.setProperty("myProp","updates/"+dirNumber);
   But what do I need to specify in the XML file ?

*  Is it correct what I did in the special appender ? I specified the
file which must include the system property and the same file as the
main appender, 
   is this the good way.


Thank u for any hints!

This should do what you want:
1. Switch to XML config.
2. Define your main appender and special appender
3. Use a system property for the name of the file in the special
appender.
4. Make sure you have your loggers setup so logs from the special part
of your code go to the special appender.

Re: log4j1.3 alpha8 using joran configurator logs text in folds(multiples)

Thanks for your help, I am placing the log4j configuration in classes folder 
,and refer  to the file location using sytem property in xml.
  
Thanks

  If you are calling doConfigure in doGet of each servlet then it is
being configured multiple times -- once for each request processed.
The easiest way to configure it only once is to put the config file in
the classpath and allow it to be automatically configured. An
alternative is to call doconfigure in static code that is only called
once.
