HAPI Server JSP Demo
This is a HAPI Server.
More information about this type of server is found at GitHub.
This implementation of the HAPI server uses Autoplot URIs to load data, more information about Autoplot can be found here.

The HAPI server verifier will test this HAPI server for correctness.
