AW: Communcating An Own Properties-Object To log4j As Substtution For System-Properties

2012-11-19 Thread Malte.Kempff
 
Hi Jake,
Yes, sorry, I probably hoped to find somehow a solution by configuration.
Your way seems to be the only one, so I'll go for it, even though I probably 
need to ask for the particular class the appender belongs to.

Thanks

Malte

I have to say, I'm very confused as to exactly what you are asking.

I told you how you can configure using custom properties without resorting to 
system properties.  You said I was missing the point even though, after 
re-reading, I believe the answer I provided directly addressed your question.

I then told you how you can directly reconfigure an appender, along with one 
example of how you can get a handle on an appender (there are others - read the 
API docs).  You responded saying that this example, somehow, reflected a of 
lack of flexibility in Log4j.

I'm at a loss.  Please restate what it is that you are aiming at here, because 
I cannot figure it out.

 Hi Jake,
 I see. But if the log4j-config is reloaded each time that application is 
called, the appender gets loaded with the current values of the Properties 
(actually System.properties). I ried that already.
 If I get the way of your sugesstion right, the application itselve would be 
supposed to code the configuration for a certan appender type. That is 
probably doable, but seems to me a bit contradictional to the ability to 
configure appenders of what kind ever. I mean why should an application know 
about what appender type and name is used in log4 configuration? I am afraid 
the logger then is loosing a lot of configuration flexibility, does'nt it?

 Yes, but that file-based configuration is only read once, and the appender 
only sees the fully resolved value and does not maintain the 
${propertyname} for dynamic runtime substitution.  Even the solution I 
proposed only applies the one time.  It just allows you to define local 
properties rather than depending on System properties set JVM-wide.
 
 You have to obtain an reference to the appender object and re-set its 
properties.  This is most certainly doable.  Just look up a logger that the 
appender is assigned to and use getAppender(appenderName).  Then you can 
modify the appender to your heart's content.

 Hi Jake,
 Thanks for the hint. But I am afraid that is not quite that what I ment.
 Looking at the example below there is the following line:
 param name=string4Construction value=${input.file.path}/param
 Here the parameter string4Construction gets a value from the 
SystemProperty input.file.path.
 So actually if the SystemProperty's value is MyInputFile.txt then 
the parameter string4Construction got  exactly its value 
MyInputFile.txt.
 The syntax ${propertyname} is already built in somewhere of log4j, I 
think, which means that it will be looked at runtime on the 
System-Properties for getting the value of the property named here.
 If I knew where in the code of log4j that resolving takes place, I 
could may be understand how to manage it, to give dynamigly own 
Properties-ojects while run-time.
 Since there was no special code needed for inventing own parameters, 
but producing setter-methods in the customized appender, I believe 
log4j binds the parameters by reflection.

 Well, you can manually bind properties at configuration time by 
loading the config as a properties object, adding more properties, and 
then calling
 configure(Properties) [1].  It's not clear to me how this might be 
done with XML configuration, thought I vaguely recall it being talked 
about in the past?

Is there a method, with that you are able to tell an apender to get an very own

right now my appender configuration looks liek that:

  value=%d{ISO8601} %-5p %m%n / 
/layout 
/appender

I would like to tell the an appender, by using a log4j-method within a certian 
application init-time.

Is there something like that or is something like that planned in a later 
version of log4j?
(Is there any chance something like that would work at all?)

Hi Gary,
finally I found the trouble. It got nothing to do with log4j itself. It is the 
stuff around my application, since I comuniate the input file names within 
Systemproperties, that are filled by one but not by the other application. The 
logger produces empty files for each, even though the other application not 
even running.  I guess the cause of this is that I am using just one logging 
config for all my applcations. I probably could fix this behaviour by using for 
each application an own logger config.

Inkow, using system properties is not the best choice, because they are global. 
That makes thread safety impossible. For a long term I should overthink the 
comunication of properties to my NamedFileAppender.
Is there another way to build up a file name for the logging using things like 
input file names may be with appenders that are shiiped with log4j?

Hi Malte,

You should probably file a Bugzilla issue but I am not sure how much
help you'll get here because you are using custom code. There you can
attach all the files you want.

Can this be reproduced in any way with a stock appender of any type like
a rolling file appender?

The best way to get anyone to help is to create a standalone program
that illustrates the problem. Ideally, it should be a unit test that
fails.

Another question that will come up is, does using the current version,
1.2.17, work better? Differently?

think, which means that it will be looked at runtime on the 
System-Properties for getting the value of the property named here.
 If I knew where in the code of log4j that resolving takes place, I 
could may be understand how to manage it, to give dynamigly own 
Properties-ojects while run-time.
 Since there was no special code needed for inventing own parameters, 
but producing setter-methods in the customized appender, I believe 
log4j binds the parameters by reflection.

Substtution For System-Properties
 
 
 Well, you can manually bind properties at configuration time by 
loading the config as a properties object, adding more properties, and 
then calling
 configure(Properties) [1].  It's not clear to me how this might be 
done with XML configuration, thought I vaguely recall it being talked 
about in the past?

 Hi to all (again),
 I just thought on theoretical level. My problem, using log4j in a 
mulithraded environment using  Apender that create file names using 
property input could only work, if it is possible to give the appender 
(log4)  An own properties-object, rahter than using the 
Systm-Properties.
 Is there a method, with that you are able to tell an apender to get 
an very own Properties-Object with out the need to change the 
configuration possibility using ${propertiesname} to address the partcular 
property?
 
 right now my appender configuration looks liek that:
 
 appender name=xsd-check 
class=de.cmk.log4j.NameComposingFileAppender
param name=string4Construction 
value=${input.file.path}/param
   
param name=inputRegex value=(.*)/param
param name=file value=logs/[user.name]/XSDCHECK.(0).log 
/param
param name=Append value=false /
layout class=org.apache.log4j.PatternLayout
param name=ConversionPattern 
  value=%d{ISO8601} %-5p %m%n /
/layout
 /appender
 
 I would like to tell the an appender, by using a log4j-method within 
a certian application init-time.
 
 Is there something like that or is something like that planned in a 
later version of log4j?
 (Is there any chance something like that would work at all?)
 
 thanks in advancs for any hints
