public class JsonPathCalculatorServlet
extends JsonComposerServlet

This servlet allows calculating paths between nodes of the graph discovered by JsonComposerServlet.

Answers to POST HTTP calls. Source and target nodes ar given as input and paths (if exists) are returned as sequence diagrams indicating the set of calls to follow such path.

As the web application does not save the state, this servlet repeats the functinality provided by JsonComposerServlet.
