tapestry-resteasy is just bringing RESTEasy to Tapestry. There's no dependency to JPA/Hibernate. Do you mean the PersistenceService in the example on the page under "Code your singleton resource"? That's not a necessity, just an example for a Rest resource. In your case, you would use Agrest instead.
You don't need to edit web.xml because tapestry-resteasy uses a Tapestry HttpServletRequestFilter to piggyback Tapstry itself, instead of going through the a custom servlet defined in the web.xml. Everything that would be done in the web.xml is done with code instead. This way, you don't need an extra Bridge to handle service injection. https://github.com/tynamo/tapestry-resteasy/blob/master/src/main/java/org/tynamo/resteasy/ResteasyRequestFilter.java The next steps for simple proof-of-concept would be something like this: - add tapestry-resteasy to your project - write a service to setup the AgRuntime - write a simple resource with a single @GET method using Agrest - contribute the AgRuntime and resource like in my previous mail. - test it with your browser or curl Hope this helps!
