APR based Apache Tomcat Native Library

I want better performance running OpenAM on Tomcat application server, thus I spent the effort to configure APR (Apache Portable Runtime) for Tomcat.

As usual (this is not my 1st time), I always encounter this error whenever I start Tomcat after configuration:

Nov 30, 2011 4:01:23 PM org.apache.catalina.core.AprLifecycleListener init



INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /am/bin/jdk1.6.0_27/jre/lib/amd64/server:/am/bin/jdk1.6.0_27/jre/lib/amd64:/am/bin/jdk1.6.0_27/jre/../lib/amd64:/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib

 
This is a very silly mistake for not following the instruction carefully.
 
The resolution is to add the following to catalina.sh:

[am@testMachine bin]$ vi catalina.sh


JAVA_OPTS="-server -Xms2048M -Xmx2048M -Djava.library.path=/usr/local/apr/lib"
