Increasing log4j categories level

[tomerbd]

In log4j.xml I see

<!-- ================ -->
<!-- Limit categories -->
<!-- ================ -->

is there a possibility to increase some categories level ?
something like

<category name="someclass">
<priority value="DEBUG"/>
</category>

while the rest will still be in INFO level?

(I tried it for a class of mine and it didnt work I have initialized my logger like this: )

public static Logger _log = Logger.getLogger("someclass");

[tomerbd]

And in log4j file i have placed

<category name="someclass">
<priority value="DEBUG"/>
</category>

[tomerbd]

it cant be seen i will remove the bigger smaller signes....

category name="someclass"
priority value="DEBUG"/
/category
