When I debug tomcat, the broswer start but get 404:
HTTP Status 404 - /
type Status report
message /
description The requested resource is not available.
Apache Tomcat/7.0.75
The Tomcat Catalina Log and Server Log all have this below error:
The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /Users/luowensheng/Library/Java/Extensions:/Library/Java/Extensions:/Network/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java:.
I searched SO, find a similar post:
What does "The APR based Apache Tomcat Native library was not found" mean?
My software environment is:
Mac OS
IntelliJ IDEA
HTTP Status 404 - /
This error is caused due to many problems for example:
> $cataline_home/webapps/your-project| > -->html,css,images, etc. > -->WEB-INF| > -->classes (your java files) > -->lib (your libraries)
javac
on command prompt or using java -versioninstalling Tomcat APR in MAC is HERE and for Linux following is tested by myself
INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path
Prerequisites for installing APR APR library APR-util library OpenSSL library
yum install openssl-devel
yum groupinstall "Development Tools"
mkdir tomcat-apr
cd tomcat-apr
wget http://www.us.apache.org/dist//apr/apr-1.5.2.tar.gz
tar -zxvf apr-1.5.2.tar.gz
cd apr-1.5.2
./configure
make
make install
The default installation path is /usr/local/apr
Download and Install APR-util
wget http://www.eu.apache.org/dist//apr/apr-util-1.5.4.tar.gz
tar -zxvf apr-util-1.5.4.tar.gz
cd apr-util-1.5.4
./configure --with-apr=/usr/local/apr
make
make install
The default path of installation is /usr/local/apr/lib Install JNI Wrapper for APR used by Tomcat (libtcnative)
cd $CATALINA_HOME/bin
tar -zxvf tomcat-native.tar.gz
cd tomcat-native-1.1.29-src/jni/native
./configure --with-apr=/usr/local/apr --with-java-home=/var/java/jdk1.7.0_45
make
make install
The native libraries were installed in /usr/local/apr/lib Integrate APR with Tomcat There are two ways to set Tomcat integrate with APR.
One is you can add the following parameter when start up the Tomcat in bin/catalina.sh: CATALINA_OPTS="-Djava.library.path=/usr/local/apr/lib"
The other is to add a new environment variable LD_LIBRARY_PATH in /etc/profile:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/lib
Then makes it effect via:
source /etc/profile
After restarting the Tomcat service, we can get the following message in catalina.out log if APR was installed successfully.
