Hi folks,
I'm getting some exceptions with a vanilla Tomcat 5.5.28 and a simple
logging valve. I'm using the following version of Java:
java version "1.5.0_22"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_22-b03)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_22-b03, mixed mode)
The valve I've configured inside a Host element:
<Valve
classname="org.apache.catalina.valves.FastCommonAccessLogValve"
resolveHosts="false" rotatable="false" pattern="combined" />
Below I'm including the stack trace I receive, and below that, the full
server.xml including the fragment above.
Am I way off the path on configuring a logging valve?
Thanks!
