Witness the IDEA docs https://www.jetbrains.com/idea/webhelp/enabling-web-service-development-support-through-a-dedicated-facet.html, which say that one can add a RESTful web service interface to an existing module in IDEA 9.
It turns out not to be true. If I follow these instructions I am given the following choices: Apache Axis, Glassfish..., JAX_RPC, XFire 1.X... No RESTful.
If I create a NEW module, it does give the RESTful option. But that doesn't help me, since I have a mature web application for which I'd like to add a RESTful interface.
Did I miss something? Is there a workaround?
