Logging.xml

Question

how could i specify the Custom formatter and handler at logging.xml?
While controlling programmatically, the logger works great and I am getting the perfect log as expected.
How can I do that at design time? I tried in one of the way, here even the file has not been creating it.
In a programmatic way i was able to do it, here i given the example
public static void log(final Level level, final Class obj, final String method, final String message, final Object... params)
FileHandler cfh;
try
cfh = new FileHandler("E:\\11.3\\Oracle\\jdev\\system11.1.1.3.37.56.60\\DefaultDomain\\servers\\DefaultServer\\logs\\mylog.txt");
cfh.setFormatter(new java.util.logging.SimpleFormatter());
cfh.setLevel(level);
ADFLogger aDFLogger = ADFLogger.createADFLogger(obj);
aDFLogger.addHandler(cfh);
aDFLogger.logp(level, obj.getName(), method, message);
aDFLogger.entering(obj.getClass().getName(), method, message);
catch (IOException e)
Here the sample ouput:
Aug 12, 2010 4:27:40 PM org.as.queries.OfficeEventVOImpl About to call service, AS0100F
FINE: Entering ...
Aug 12, 2010 4:27:40 PM org.as.queries.OfficeEventVOImpl About to call service, AS0100F
PERF: Entering ... About to call service, AS0100F
"54N     " "SERVER ID     " "USERID     " "AS0100N     " "Web: OfficeEventVOImpl.retArrayFromService():AS0100F     " "Start Time : 08/12/2010 16:27:40"
My try with logging.xml which didn't even created a file.
<log_handler name='perf-handler' class='java.util.logging.FileHandler' formatter='java.util.logging.SimpleFormatter' level='ALL'>
<property name='path' value='${domain.home}/servers/${weblogic.Name}/logs/perf.log'/>
<property name='maxFileSize' value='10485760'/>
<property name='maxLogSize' value='104857600'/>
<property name='encoding' value='UTF-8'/>
</log_handler>
<logger name='org' level="ALL">
<handler name='perf-handler'/>
</logger>

Arun,
I played around a bit with your test case and it reproduces. I surmise the following:
logging.xml is the configuration file for the Oracle Diagnostic Logger, and as such, I infer (it doesn't seem to be documented anywhere) that you can only use the ODL handlers in there (I was able to use other formatters). The logging.properties file (in jre/lib) can use the standard handlers. What I did was to use the ADFLogger in my code - if I configure logging.properties with a file handler, the log message shows up in all of the ODL logging places as well as in the file specified in my FileHandler.
So, although it doesn't appear to be documented anywhere that I can find, if you want to use non-ODL handlers, you can configure them in the standard java.util.Logging configuration file, logging.properties.
