If you import the JDF Spring Resteasy example into JBDS and then:
1. right click on the project in Project Explorer
2. Run As
3. Run on Server
4. click Finish
The example is deployed on server (if you have configured one in Server tab) and the internal web browser window shows up with address http://localhost:8080/jboss-spring-resteasy/. And user sees HTTP 404 Could not find resource status.
The following URL should be used automatically (taken from README.md):
http://localhost:8080/jboss-spring-resteasy/hello?name=yourname
