cxf:logging not working...

[STEVEN THEIN]

Hi,

I had the following defined in my cxf.xml file. When I run our Web 
Services using Web Logic 11gR3, the request and response messages are 
not written out  to the console.
Is there any thing,  I need to configure on CXF side or on WebLogic side?
<cxf:bus>

<cxf:features>

<cxf:logging />

</cxf:features>
</cxf:bus>

Thanks
Steve
