/** Note this is simply a copy of com.jamonapi.http.JAMonTomcatValve. Tomcat 5.5 would not work with the valve in the same jar as the jamon classes
 * and also display stats in jamon.war.  Simply compile this class sepeartely and put it in tomcats /server/classes/com/jamontomcat/http and put jamon-2.7.jar or higher in tomcats
 * common/lib directory.   Note this class should also work in tomcat 6 although it is easier simply to put jamon-2.7.jar (or higher in the server/lib)
 * for tomcat 6.
