GraphsServlet

public GraphsServlet()

A default constructor, used usually by a servlet engine.

GraphsServlet

public GraphsServlet(String mobyEndpoint,
                     String mobyNamespace)
              throws MobyException

A real constructor that is called when it is known what Moby registry we are going to serve for. All instances of GraphsServlet are stored in a hashtable so when a call for already known combination of 'mobyEndpoint' and 'mobyNamespace' comes a proper instance of GraphsServlet is either restored from the hashtable, or created.

Throws:

MobyException
