   <filter-class>net.ontopia.topicmaps.nav2.taglibs.tolog.TologContextFilter</filter-class>
   <init-param>
     <param-name>topicmap</param-name>
     <param-value>opera.xtm</param-value>
   </init-param>
   <init-param>
     <param-name>reqParam</param-name>
     <param-value>topicmap</param-value>
   </init-param>
