title: Tomcat 7 maxSpareThreads ,liveDeploy ,debug
body: <p>The following warnings are reported when I start Tomcat 7:</p>
  <blockquote>
  <p>Jan 20, 2011 8:27:50 PM org.apache.catalina.startup.SetAllPropertiesRule begin
  WARNING: [SetAllPropertiesRule]{Server/Service/Connector} <strong>Setting property 'maxSpareThreads' to '75' did not find a matching property.</strong></p>
  <p>Jan 20, 2011 8:27:50 PM org.apache.tomcat.util.digester.SetPropertiesRule begin
  WARNING: [SetPropertiesRule]{Server/Service/Engine/Host} <strong>Setting property 'liveDeploy' to 'false' did not find a matching property.</strong></p>
  <p>Jan 20, 2011 8:27:50 PM org.apache.tomcat.util.digester.SetPropertiesRule begin
  WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} <strong>Setting property 'debug' to '0' did not find a matching property.</strong></p>
  </blockquote>
  <p>Why are these warnings being reported? The properties mentioned are specified in the <code>server.xml</code> file, which was created for Tomcat 5.5.</p>
  <p>I want to know what are the alternatives in Tomcat 7. Should I just remove these parameters from server.xml or is there a better solution?</p>
