To run (you need maven) execute mvn jetty:run and application will run on port 8090 - http://localhost:8090
If you do not need to test internal services (behind firewall), you can use rest-client.com as well.
To create deb package, you need oh-deb-build (https://github.com/pete911/oh-deb-build) installed. Run:
./build <build_number>
Which will generate _oh-rest-client_0.1-<build_number>all.deb package. Before you install the package you will need oh-tomcat-app (https://github.com/pete911/oh-tomcat-app) installed.
Application is installed to /opt/oh-rest-client directory. Logs are in /var/log/oh-rest-client and configuration is in /etc/default/oh-rest-client.
