The APR based Apache Tomcat Native library was not found on the java.library.path

Getting this message when running JasperServer :

The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path

The Apache Portable Runtime is a highly portable library that is at the heart of Apache HTTP Server 2.x. APR has many uses, including access to advanced IO functionality (such as sendfile, epoll and OpenSSL), OS level functionality (random number generation, system status, etc), and native process handling (shared memory, NT pipes and Unix sockets).</div></blockquote>

It allows tomcat to use OS functionalities not provided in the Java Runtime (such as sendfile, epoll, OpenSSL, system status, etc.). Tomcat will run just fine without it, but for some use cases, it will be faster with the native libraries.</div><div style="background-color: white; border: 0px; clear: both; color: #242729; font-family: Arial, "Helvetica Neue", Helvetica, sans-serif; font-size: 15px; font-stretch: inherit; font-variant-numeric: inherit; line-height: inherit; margin-bottom: 1em; padding: 0px; vertical-align: baseline;">If you really want it, download the tcnative-1.dll (or libtcnative.so for Linux) and put it in the bin folder, and add a system property to the launch configuration of the tomcat server in eclipse.</div><pre style="background-color: #eff0f1; border: 0px; color: #242729; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; font-stretch: inherit; font-variant-numeric: inherit; line-height: inherit; margin-bottom: 1em; max-height: 600px; overflow: auto; padding: 5px; vertical-align: baseline; width: auto; word-wrap: normal;"> -Djava.library.path=c:\dev\tomcat\bin</pre>
