New to Java

I started using DWR (great product), however I am tired of looking at the DWR logging messages on the console.

Example:
12:28:21,438 INFO [ExecuteQuery] Executing: public java.util.List com.at.struts
.dwr.RetreiveActionItems.getCompletedItems()

I am running JBoss and I tried to disable it in the log4j.xml by doing the following:

<category name="uk.ltd.getahead.dwr">
  	<priority value="ERROR"/>
  	<appender-ref ref="TRAP_LOG"/>
  </category>
  
  <category name="com.at.struts.dwr">
    	<priority value="ERROR"/>
    	<appender-ref ref="TRAP_LOG"/>
  </category>

Could someone please tell me how to disable logging for DWR?
