Apache Tomcat Native library
My standalone Tomcat 6 informs me, at startup, that
The APR based Apache Tomcat Native library which allows optimal
performance in production environments was not found on the
java.library.path:...
Does this library offer any benefit to standalone systems, or is it
purely for use with Apache httpd + Tomcat?

Actually, you can use both if you want. I'm not sure it actually makes
that much difference unless you want to have *lots* of persistent
connections served by a smaller number of actual request processors.

Hi Paul,
APR is a native HTTP implementation (heart of the Apache HTTP Server).
It provides a better performance for handling the http overhead in
Tomcat's request processing.
See http://tomcat.apache.org/tomcat-7.0-doc/apr.html for more details.
If you use Apache Webserver with Tomcat you wouldn't use APR but AJP.

And if you are tired of seeing the error message in your logs, you can comment out the AprLifecycleListener in your server.xml file.

It's most beneficial when you don't have httpd in front of Tomcat and are processing a lot of HTTPS traffic.
If you're satisfied with your current performance, don't worry about it.
