servlet.log not working in struts/tomcat environment

I can't figure out how to send logging info to the tomcat log file.
I *think* Tomcat's log is specified in tomcat/conf/server.xml and have modified the following Logger element:
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="realationships_server" suffix=".log"
timestamp="false" verbosity="4"/>
When peeking at the log file in the tomcat/logs dir, my servlet.log info is not appearing.
The web.xml file has the following entry:
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>4</param-value>
</init-param>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<init-param>
<param-name>application</param-name>
<param-value>ApplicationResources</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
Could it be that servlet.log(...) is not the correct api call to make within the struts framework (i.e my action class and action form) or is my environment incorrectly set up.
Any help would be much appreciated.

Solution found! I added the jars files to the lib dir from a struts application that was working and archived the old ones. Works fine now.
Reason? Unknown - what irks me is that no logging info (servlet.log) was being sent to the tomcat logger and no exceptions were being reported. I was getting a blank xxx.do page appearing.
 
please buy this thing and then I get a fat cut of the action:
