How do you define your logger in your Java code? I'm suspicious that the
logger name you've defined as "MyClass" is merely the simple name of the
class, not the fully qualified name of the class that you've likely defined it
for your logger name.
That is, if "MyClass" is in the package "com.mypackage", and you've defined
the logger using something like...
Logger logger = Logger.getLogger(MyClass.class);
OR
Logger logger = Logger.getLogger(MyClass.class.getName());
...then your configuration should be....
<logger name="com.mypackage.MyClass">
<level value="DEBUG" />
</logger>
Note that "additivity" is "true" by default and need only be specified if you
want to set it to "false" (which would mean you wouldn't inherit
appenders/levels from ancestor loggers).
Also note that "priority" is the deprecated name for "level". It will work
the same, but you should just use "level" to avoid confusion.
Finally, you mention you want all other classes to log at the ERROR level, yet
you defined the level in "root" as INFO. Typo?

Hi,
I have tried it with the following configuration :
<appender name="Log1" class="org.apache.log4j.RollingFileAppender">
<layout class="org.apache.log4j.PatternLayout">
</layout>
</appender>
<logger name="MyClass" additivity="true">
<level value="DEBUG" />
</logger>
<root>
<priority value="INFO" />
<appender-ref ref="Log1" />
</root>
I want MyClass logs of DEBUG level and all other classes of ERROR in
"log1.log" file as mentioned in logger "Log1". But it isnt happening. Am not
getting any DEBUG logs in "log1.log" whereas if I set the level in appender
"Log1" to DEBUG, I do get the DEBUG logs of Myclass in log1.log. I am sorry
if am still making some mistake here. Please correct me where am I wrong.
Thanks for such quick replies.

What I've provided does exactly what you are asking for. Setting your
class
logging level to DEBUG overrides the inherited level from root for the
specified logger name. Why don't you just try it and see what it does
rather
than speculate on why you believe it wouldn't work? You can also read try
reading the docs...

So when root level is ERROR and i set Myclass level to DEBUG, how will
the
Myclass's DEBUG logs get logged since the root level is ERROR and it will
block the DEBUG logs ? What i know is that, if I set root level to DEBUG
and
some particular class (say Myclass) logger level to ERROR then, all
classes'
logs of DEBUG will get logged but not of Myclass as its restricted to
ERROR.
But what I want is the vice-versa. I want ERROR level of all classes and
DEBUG of only few important classes. I am new to log4j so maybe what i am
sayin is wrong.

If you name your loggers by class name, then sure. This is standard
logging
configuration, not some extra special workaround.
<logger name="com.mypackage.Myclass">
<level value="debug"/>
<!-- inherits A1 appender from root, applies only to
com.mypackage.MyClass
-->
</logger>
<logger name="com.myotherpackage">
<level value="debug"/>
<!-- inherits A1 appender from root, applies to all classes in
"com.myotherpackage" -->
</logger>
<root>
<level value="error"/>
<appender-ref ref="A1"/>
</root>

Hi,
Is it possible to set logging level for few selected classes in
appender
to
DEBUG and rest all ERROR ? Is there any combination of filter that can
do
this ?
