Problem installing RESTEasy jars

When I go to JBoss Tools -> Create a Sample RESTful Web Service, I get the error message

RESTEasy jars not found in the runtime associated with the selected project. Make sure RESTEasy is installed and try again

I created an eclipse User Library, associated it with all the RESTEasy jars, and added the library to the classpath of a dynamic web project, but I still see the same error message.

I'm using version 5.0.0.M2 of JBDS and AS 5.1.0.

Also, btw, the RESTEasy example isn't showing up under Help -> Project Examples...

I can certainly believe that it's just a configuration or installation error on my part. Any help would be appreciated.
