Apache Portable Runtime and Tomcat

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).

APR support requires three main native components to be installed:

• APR library
• JNI wrappers for APR used by Tomcat (libtcnative)
• OpenSSL libraries

wrapper library sources are located in the Tomcat binary bundle.The file is in the bin/tomcat-native.tar.gz . Once the build environment is installed and the source archive is extracted, the wrapper library can be compiled using (from the folder containing the configure script):
./configure && make && make install

First I need to install the APR on my local machine

that I needed to downlod the APR and the APR util in to the same machine and install it in th /usr/local/apr then I compiled the native code of the comcat then that succeed

./configure --with-apr=/usr/local/apr/
make clean && make && make install
-------------------------------------------------------------------------------------------
Check wether the tomcat uses this APR in their process -

then at this java.library.path it search as
INFO: The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /home/sandakith/software/jdk1.5.0_06/jre/lib/i386/client:/home/sandakith/software/jdk1.5.0_06/jre/lib/i386:/home/sandakith/software/jdk1.5.0_06/jre/../lib/i386

Then what needed to be done is to include those created libs at /usr/local/apr/lib to the one of the location that it complains that it can not find that

other way is that you can edit the java,library.path - still not done:)
Then that thing in the catalina.out will not be visible and it will optimize the performance using this native libraries
