Hi,
My problem is some what similar to one mentioned in this link
(http://www.jajakarta.org/log4j/jakarta-log4j-1.1.3/docs/deepExtension.html)
In brief, I am building an abstraction layer which encapsulates (through
composition) logger object but user also passes additional information (say
component name, classification of log messages (used by inhouse build viewing
application) etc., Both component name and classification categories are in
addition to FQCN i.e. logger names.) in each invocation of printing methods
which need to be passed through various components of logging framework say
extending appender and layout class for finally written to its target
destination. The user would specify the layout in the configuration file how to
format the message.
Example:
public class Test {
private static Logger logger = Logger.getLogger(Test);
public void testmethod()
{
logger.info(msg, componentName1, classification1...);
logger.info(msg);
}
public void testmethod1()
{
logger.debug(msg, componentName2, classification2,...);
}
}
So for each invocation of printing method (irrespective of levels) the
additional information like componentName and classification can be different.
Hence, this information need to be stored in loggingEvent (if I remember for
each invocation of printing method loggingEvent object is created and hence, I
need to extend it to pass this additional information so that finally layout
object will format according to the pattern specified by user in the
configuration file). Kindly let me know if the extension of loggingEvent method
is appropriate one, if not then let me know how to proceed further. It would be
of great help if pointers to some example is provided.
If my example is not explainatory enough then kind let me know so that I will
try to rephrase or provide more information.
PS: Also let me know if setting a resourcebundle in a parent logger does it
boils down to its children?
As far as I looked and found that this setting of resource bundle cannot be
achieved through configuration right?

Jain
