dLibra server location and directory used for storing workspaces should be configured in src\main\resources\connection.properties file. A dLibra instance used for demonstration purposes is available at host sandbox.wf4ever-project.org (port number 10051 and directory 3, as originally configured).
That's all, now the project can be built (mvn package) and deployed (rosrs5 servlet).
