Hello All,
Thanks Jin.
Well now i think its more convenient to have the logging event itself at the
JMS receiving end.
So in my message driven bean when i get the logging event i
Create an category instance for category JMSReceiver
Fetch the message using event.getMessage
Fetch the category of the message and concat the category and
message
Fetch the string representation of Exception, if any using
event.getThrowableStrRep() and then create a instance of
throwable
Get the priority of the message and then call the appropriate method
with argument : message, exception.
JMSReciever category have attached RollingFileAppender and logs the message
in the file, with desired layout.
Regards
Naresh
