Thanks Konstantin for the clarification!

I stand corrected: the message notifies that (APR-based) Tomcat Native library is not available on the java.library.path. 2) Compile your own native APR library, as the page suggested: http://tomcat.apache.org/native-doc/ I stand corrected: You can compile your own (APR-based) Tomcat Native library, and for that you need APR libraries installed. Cheers!
Re: Tomcats warning message about APR library
Emir, The actual list of steps is at the link you mentioned earlier: http://tomcat.apache.org/native-doc/ On Fri, Mar 6, 2015 at 7:30 AM, Neven Cvetkovic neven.cvetko...@gmail.com wrote: Let us know if you need help compiling the native Tomcat connectors (APR-based). There might be others that want to compile their TCNATIVE (apr-based) connectors, so here's the digested list below (for Ubuntu/Debian based systems): 1) Install required libraries for building TCNATIVE (APR dev, APR, and SSL tools) sudo apt-get zlib1g-dev build-essential libapr1 libapr1-dev libssl-dev 2) Unpack TC-native source, e.g. cd /opt/apache-tomcat-8.0.20 cd bin tar zxvf tomcat-native.tar.gz 3) Change directory to TC-native source code, e.g. cd /opt/tomcat/bin/tomcat-native-1.1.32-src/jni/native/ 4) Prepare makefile for compiling source, e.g. ./configure --with-apr=/usr/bin/apr-config --with-prefix=/opt/tomcat 5) Compile code, e.g. make 6) Install libraries, e.g. make install 7) This will add libraries to: /opt/tomcat/lib You can see the actual things installed: /opt/tomcat/lib/pkgconfig /opt/tomcat/lib/pkgconfig/tcnative-1.pc /opt/tomcat/lib/catalina-storeconfig.jar /opt/tomcat/lib/libtcnative-1.a /opt/tomcat/lib/libtcnative-1.so.0.1.32 /opt/tomcat/lib/libtcnative-1.so.0 /opt/tomcat/lib/libtcnative-1.la /opt/tomcat/lib/libtcnative-1.so 8) Now we need to let Tomcat know about these libraries and add them to the library path. Add a new file, e.g. /opt/tomcat/bin/setenv.sh file: export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${CATALINA_HOME}/lib 9) Restart Tomcat,e.g. /opt/tomcat/bin/catalina.sh run 10) Observe the output, you should see something like this in the console log: INFO [main] org.apache.catalina.core.AprLifecycleListener.lifecycleEvent Loaded APR based Apache Tomcat Native library 1.1.32 using APR version 1.5.1. INFO [main] org.apache.catalina.core.AprLifecycleListener.lifecycleEvent APR capabilities: IPv6 [true], sendfile [true], accept filters [false], random [true].

Re: Tomcats warning message about APR library
Hey Emir, I've done a little test on my Ubuntu VM. Read below my additional comments: On Fri, Mar 6, 2015 at 5:41 AM, Neven Cvetkovic neven.cvetko...@gmail.com wrote: You have two choices: 1) Find a specific package that includes the required packages, e.g. apt-get install libapr1 libapr1-dev apt-get install libtcnative-1 (I have not tested these, you need to look through the packages and find out exactly which one you need) If you decide with option (1), you could install libtcnative-1, and that will install the following files for you: $ dpkg --listfiles libtcnative-1 /. /usr /usr/share /usr/share/lintian /usr/share/lintian/overrides /usr/share/lintian/overrides/libtcnative-1 /usr/share/doc /usr/share/doc/libtcnative-1 /usr/share/doc/libtcnative-1/copyright /usr/share/doc/libtcnative-1/README.Debian /usr/share/doc/libtcnative-1/changelog.Debian.gz /usr/lib /usr/lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/pkgconfig /usr/lib/x86_64-linux-gnu/pkgconfig/tcnative-1.pc /usr/lib/x86_64-linux-gnu/libtcnative-1.a /usr/lib/x86_64-linux-gnu/libtcnative-1.so.0.1.29 /usr/lib/x86_64-linux-gnu/libtcnative-1.so.0 /usr/lib/x86_64-linux-gnu/libtcnative-1.so Notice the version number is x.1.29 After adding /usr/lib/x86_64-linux-gnu to your LD_LIBRARY_PATH, your Tomcat will be able to find the libtcnative-1 libraries on the the library path (java.library.path). If you try using this package with the latest Tomcat 8.0.20 - you will run into a problem of incompatible libraries, e.g. SEVERE [main] org.apache.catalina.core.AprLifecycleListener.init An incompatible version 1.1.29 of the APR based Apache Tomcat Native library is installed, while Tomcat requires version 1.1.32 Notice the latest Tomcat 8.0.20 requires version 1.1.32. So, the (apt-get installed) TCNATIVE shared library was found on the library path, but it was incompatible version, and Tomcat would not start APR-based connectors, but rather revert to default (NIO for Tomcat8, BIO for Tomcat7). Which brings my original point - I prefer to compile my own TCNATIVE (APR-based) libraries to using the vendor packaged libraries (CentOS yum or Ubuntu apt-get). It takes time for vendor to package and distribute a new release of packaged software, so you might be better of recompiling these pieces yourself. How did you install tomcat8? Did you use apt-get package or did you download the standard ZIP/TAR package from Tomcat's page? Good luck! Let us know if you need help compiling the native Tomcat connectors (APR-based). Cheers!

I prefer this way, as I deal with various Linux flavours (RHEL, CentOS, Ubuntu) and they all have their own packages. It takes time (longer than I want to wait) for the vendor to make these Tomcat packages. You can get your own Tomcat installed and upgraded the very same day a new Tomcat release is out. Also, Tomcat team makes it very convenient for Windows users with the Windows binaries included, and recompiling on Windows requires extra effort setting up the tools. This is where I found the info that I need to install it: http://tomcat.apache.org/native-doc/ What am I missing here? I'm using tomcat 8 btw. How did you install tomcat8? Did you use apt-get package or did you download the standard ZIP/TAR package from Tomcat's page? Good luck! PS. I will try locating the actual package and test it on my Ubuntu VM.

Re: Tomcats warning message about APR library
Thanks Neven for your answer and the steps (Hvala puno!). Thanks everyone for your answers. @Christopher Schultz Both their answers were more than helpful, and I learned something new. No offense but your reply was kind of unnecessary, just because I learned nothing new. Thanks again guys!
