A java web server for ebarimt's VAT bill on Linux OS.
Download library files from https://ebarimt.mn/posapi for Linux OS.
Extract PosAPI_2.1_libs_Linux.zip.
$./install.sh #x64 copies all so library files to /usr/libs and creates links.I tried on Centos 7, java 1.8. So it requires to install few packages, if you're using other linux distributors it will also requires packages shown below:
$yum group install "Development Tools" #gcc, g++ compiler but its older version $yum install devtoolset-9 #g++ higher version(mine was 9) which supports c++11 $yum install java-1.8.0-openjdk-devel #for JAVA_HOME /usr/lib/jvm/java-1.8.0-openjdk/ $yum install libsqlite3x-devel.x86_64 #installing sqlite3 $yum install centos-release-scl #enabling g++'s latest version $echo "source /opt/rh/devtoolset-9/enable" >> /etc/bashrc $export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib #adding path $yum install prelink
Need to copy libPosAPI.so file to /usr/lib folder.
Open init folder(there is a dummy libPosAPI.so) and run cmd.sh file like $./cmd.sh or $sh cmd.sh
Description of cmd.sh file:
- Compiling and linking Bridge library
$g++ -Wall -std=c++11 -c -fPIC -I/usr/lib/jvm/java-1.8.0-openjdk/include -I/usr/lib/jvm/java-1.8.0-openjdk/include/linux com_github_uugan_ebarimt_BridgePosAPI.cpp -o com_github_uugan_ebarimt_BridgePosAPI.o- G++ linker then links the C++ object files into our bridged library.
$g++ -std=c++11 -fPIC -shared -lPosAPI -L/usr/lib -o libBridgePosAPI.so com_github_uugan_ebarimt_BridgePosAPI.o -lc $cp -r libBridgePosAPI.so /usr/lib/libBridgePosAPI.so
- Testing bridge library:
$javac -d . BridgePosAPI.java && java -Djava.library.path="/usr/lib" com.github.uugan.ebarimt.BridgePosAPI getInformation = { "branchNo": "", "dbDirPath": "/root/.vatps", "posId": "", "registerNo": "" } checkAPI = { "config": { "success": true }, "database": { "success": true }, "network": { "success": true }, "success": true } result = { "success": true }
