Developing log of Amazon Web Service (AWS).


Deploy a JAVA Web Service on AWS.

Local Environment:

Eclipse Java EE, Tomcat 8.0, JNI native library

AWS Development Environment Setup:

AWS Toolkit for Eclipse:    AWS Toolkit for Eclipse Document

Generate a new RSA key and add it to GitHub: Link

Configure a HTTPS listener on load balancer:


Build OpenCV 3.2.0 (include OpenCV Java)

Prepare necessary build tools:

# install required tools
sudo yum install git cmake gcc-c++

Clone from OpenCV GitHub repository:

 # get opencv GitHub repository git clone git@github.com:opencv/opencv.git # checkout specific version tag git checkout tags/3.2.0 

Use CMake to build opencv (release version, static library)

cd opencv

mkdir build

cd build



sudo make install

OpenJDK 1.8:

Amazon Linux contains java-1.8.0-openjdk  but not java-1.8.0-openjdk-devel. In order to build OpenCV Java package, we need to install openjdk-devel. (error message example: Unable to locate tools.jar)

sudo yum install java-1.8.0-openjdk-devel

Ant 1.10.1:

Ant is also required to build OpenCV Java Wrappers. However, the version installed by yum install is no too low (1.8) which doesn’t support java-1.8.0.

Download Ant http://ant.apache.org/bindownload.cgi

wget http://www-eu.apache.org/dist//ant/binaries/apache-ant-1.10.1-bin.zip
unzip apache-ant-1.10.1-bin.zip

Export ANT_HOME as apache-ant folder and add ANT_HOME/bin to PATH

Add the following lines to .bashrc file

export ANT_HOME=~/apache-ant-1.10.1

export PATH=${PATH}:${ANT_HOME}/bin
