Running The Project:

You’ll have to use three terminal windows.
- On the first terminal window move to ‘hrm’ folder and do a ‘mvn install’.
- On the second terminal window go to ‘apache-tomcat-9.0.35/bin’ folder and run ‘./catalina.sh start’.
- On the first terminal window move to ‘HRsystem’ folder and run ‘mvn install tomcat7:deploy’.

• open ‘hrm/HRsystem/WebContent/WEB-INF’ folder and copy all .html and .css files and paste it in ‘apache-tomcat-9.0.35/webapps/HRsystem/WEB-INF/classes’.
  
• open the third terminal window and move to ‘hrm’ directory.
  
• open your browser, the link to the project is ‘http://localhost:8080/HRsystem/home/page/web’, go to the third terminal window and run ‘bash run.sh’ (you'll have to run it within 5 seconds so that the project can connect to the socket port).
