To build project use:

mvn package

You will also need Tomcat. After installing it, rename the build embassy.war package in target directory to ROOT.war and copy it to Tomcat's webapps directory.

Add a local dns record by mapping sampleland.ir to localhost in /etc/hosts:

127.0.0.1 sampleland.ir

Also, to run on port number 80, you'll need root permission. Edit server.xml file in tomcat's conf directory and set port number to 80. Then start tomcat using sudo.
