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
Malte

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?
Malte

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?

Hi to all,
I have programmed an appender dirived from FileAppender, that is
able to produce log-files with file names that you can controll in a
more flexible way.
You can use an other String, for example the input file, or
parts of it to produce your desired log file name, seq-numbers and time
stamps etc.
My applcation, that got the log-config (actually the xml
configuration type) is a mroe infratstuctional Programm, that calls
other applications like converters.
I have put all in one single log-configuration-file using the
cusomized appender on several file processing applcations.
The confguration is like this, that each processed file is
suppose to produce one log file per application that is processing it.
For one application it works pretty good. Ror another it
produces each expected log file but produces the logs for all turns only
in one file. The others stay empty.
I am not sure what I am doing wrong and what is going on here. I
cannot understand why in one case it works (s.FEDCONV...log) , in the
other it does not at all (s. XSDCHECK...log).
here the contend of the only filled XSDCHECK...log

here the content was filled obviously in the log-file of the
last File beeing processed, instead of puting them to each log, that has
already been produced.
Please find attached the source code of the appender and
dependings (*.java) , the configuration(log4j.xml), and an example of
the logging of log4j itself (log4j-log-log).
I am using log4j version log4j-1.2.15.jar
Best regards and thanks for any hints in advance
