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

The library referred to is bundled into an OS specific dll (tcnative-1.dll) loaded via JNI. 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.

We can 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.

org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER will not be exported

I had the same issue after updating my JDK in project and resolved it by replacing my .classpath file with previous one. I noticed the following changes in my .classpath file

    
         name="maven.pomderived" value="true"/>
         name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>
    

The second line was missing from above code

 kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>

This line was missing

     kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8">
    
         name="owner.project.facets" value="java"/>
    

These lines were added so I manually removed them and it all worked again.

Configuring External Apache Tomcat in Netbeans/Ubuntu or error : specify the server location (Catalina Home)) and error : could not read server-config.xml

Hi This posts counters the problem of configuration of external Apache Tomcat Server to Ubuntu..

It also deals with the errors
1. specify the server location (Catalina Home))
2. could not read server-config.xml

To Counter all this we need to do as follows

For First Problem create and link directories as follows.This will only occur if Netbeans thinks if you are using and older version of Tomcat Server.

cd /usr/share/tomcat7
sudo mkdir common
cd common
sudo ln -s ../lib lib

For Second Problem create and link directories as follows

cd /usr/share/tomcat7
sudo mkdir conf 
cd conf
sudo ln -s /etc/tomcat7/server.xml server.xml
sudo chmod o+rx /usr/share/tomcat7/conf 

Thats it give a username and Password and Apache server is configured on your Netbeans
