FileAppender problem
Hi All,
I am working on a webapplication and i have a requirment to generate log
files at run time for my impex process.here is the use case
i am validating an XML file and validation error is being handled by custom
Error handler.This error hanlde will be passed to the underlying validator
(Jaxb 2.x validator),so i have to create the log file when the instance of
this error hanlder is being created.
here is the code to create log file at run time
FileAppender appender;
try {
appender = new FileAppender(layout, sb.toString(), false);
log.addAppender(appender);
log.setAdditivity(false);
log.setLevel(Level.WARN);
} catch (IOException e) {
e.printStackTrace();
}
everything is working fine and file is being created correctly as well being
written by the logger to the respective place.
but if i restart my server real problem starts and logger starting appending
the log content not only to its pareent class as well other classes.here is
the details
lets suppose i have 3 log (A,B,C) files already at the location with 3 lines
in each log file and C was the latest file created in the process.
so when i restart my server it some how appending data in to previos all
log files in this fashin
C has still 3 lines
B has now 6 lines
A has now 9 lines
it seems that the appender i hace created is still open or have refrence not
sure what exactly going on.
any help in this regard will be helpfull.

I was thinking the same line but problem solved only by closing the appender when work done

Re: FileAppender problem
Posted by Umesh Awasthi <um...@gmail.com>.
Josef,
Thanks for the help.i able to solve the problem and here is the casue of the
problem'.
since i was creating fileappender instance
appender = new FileAppender(layout, sb.toString(), false);
inside the constructor of my class and i was of impression that log4j is
responsible for closing the appender which in my case was not happening at
all.
so after looking in to the FileAppender source code i got the hint since in
the code they tried to close the appender but code was indicating that there
may be some cases where appender might still be open and my problem was in
this section,so after doing my work i simply closed the appender and it
solved the whole issue.
still i am not sure how tomcat was keeping refrence of all the appender
created by the code since i was cleaning up my code and was making all
refrences null.
any one have idea,please do share

AW: FileAppender problem
Posted by Stadelmann Josef <jo...@axa-winterthur.ch>.
In case you have conflicts, it is a good Idea to consolidate all different log4j.properties into one big log4j.properties and have that used when TOMCAT starts. This just fior a test. If then all runs, then your problems may be that of a access conflict; i.e. trying to open a file or a channel which is already open.
It helped for me in many case.
