Tomcat 7 maxSpareThreads ,liveDeploy ,debug

Question

The following warnings are reported when I start Tomcat 7:

Jan 20, 2011 8:27:50 PM org.apache.catalina.startup.SetAllPropertiesRule begin WARNING: [SetAllPropertiesRule]{Server/Service/Connector} Setting property 'maxSpareThreads' to '75' did not find a matching property.

Jan 20, 2011 8:27:50 PM org.apache.tomcat.util.digester.SetPropertiesRule begin WARNING: [SetPropertiesRule]{Server/Service/Engine/Host} Setting property 'liveDeploy' to 'false' did not find a matching property.

Jan 20, 2011 8:27:50 PM org.apache.tomcat.util.digester.SetPropertiesRule begin WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'debug' to '0' did not find a matching property.

Why are these warnings being reported? The properties mentioned are specified in the server.xml file, which was created for Tomcat 5.5.

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?

Answer 1

the maxSpareThreads configuration parameter was removed in tomcat 6, so it's no longer valid/applicable. see the tomcat 5 documentation pages for the configuration element in question: http://tomcat.apache.org/tomcat-5.5-doc/config/http.html (maxSpareThreads is present), and absent in the corresponding tomcat 6 documentation page.
