Second, the configuration of the log:

The Tomcat logs fall into two categories:

1, access logs, record the time of access, the source of access, access to information and other related information.

2, run the log, record tomcat running information, exception, error message.

Access log configuration, in Server.xml The following tab edit, close the Access log comment The following paragraph content can be

<valve classname= "Org.apache.catalina.valves.AccessLogValve" directory= "Logs"

prefix= "Localhost_access_log" suffix= ". txt"

The meaning of each parameter
