tomcat-valve

In tomcat http access log valve takes some time to write to file. Please note I have default configurations for org.apache.catalina.valves.AccessLogValve. Are there anyways to improve the latency? And what are the key reasons for this delay I found the answer for this. You can improve the delay by disabling buffering. Flag "buffered" determine if logging will be buffered. If set to false, then access logging will be written after each request. Default value: true. Therefore, adding BufferedLogs="false" will reduce the delay in writing to the log file. Another property is

I try to implement a Tomcat valve (currently using 7.0.55) that should intercept every request that reaches the Tomcat serivce, regardless of Connector and whatnot, regardless of wether there's a Host with matching name or a servlet context or whatever. The invoke -method of the valve looks like this: public class MyValve extends ValveBase { public void invoke(Request request, Response response) throws IOException, ServletException { LOG.trace("Valve is being invoked"); getNext().invoke(request, response); } } On the dev system, testing locally, everything's working as excepted. A request to

Our web application requires custom form authentication with specific logic inside. The current form authenticator implementation requires the authenticator module, let's call it custom.auth.jar , to be present in %CATALINA_HOME%/lib before the web application starts. The web application uses that custom authenticator module using the following context.xml directive: <Valve className="foo.bar.CustomAuth" characterEncoding="UTF-8"/> As far as I understand Tomcat requirements, this module, custom.auth.jar , must be present in Tomcat's lib directory before the web application starts, because the

I'm looking to implement a custom Valve and configuring it using META-INF/context.xml. At the moment though, when context.xml is parsed during deployment, Tomcat (6.0.32) dies with a ClassNotFoundException on my custom Valve implementation. I'm under the impression that I'm running into a class loading context issue and I'm not 100% sure I understand it. Is my class not found because it is located in the WEB-INF/classes file and the Context level class loader is unable to locate the class because of the hierarchy? Thanks in advance. You can not load Valve s from inside the webapp class loader.

I have a clean tomcat7 installation with log4j enabled (according to http://tomcat.apache.org/tomcat-7.0-doc/logging.html#Using_Log4j ). "Application-level" logging do use log4j configuration (I direct logs to local syslog server). How can I make my application access.log to also use log4j? As far as I can see, I can choose among AccessLogValve, ExtendedAccessLogValve and JDBCAccessLogValve, but neighter of them enables me to log to syslog nor to use log4j. The log4j-scribe-appender project contains a Log4JAccessLogValve that will let you do just that. if you using Tomcat 7, you can extend the
