[jbossseam-issues] [JBoss JIRA] Updated: (JBSEAM-4299) Seam RESTEasy integration does not allow root resources defined with @Path("/") .

Seam RESTEasy integration does not allow root resources defined with @Path("/") . --------------------------------------------------------------------------------- Key: JBSEAM-4299 URL: https://jira.jboss.org/jira/browse/JBSEAM-4299 Project: Seam Issue Type: Bug Components: WS Affects Versions: 2.2.0.CR1 Environment: Seam 2.2.0.CR1, RESTEasy 1.1.GA, Seam RESTEasy 2.2.0.CR1, JBoss AS 5.0.GA. Reporter: Jimmie Fulton Assignee: Christian Bauer Priority: Blocker Fix For: 2.2.0.GA The RESTEasy integration in Seam throws an exception when trying to serve an "empty" root resource. The resource looks like this: @Path("/") public class RootResource { @GET @Produces("text/plain") public String getResource() { return "Root resource"; } } The request path would be "http://localhost:8080/seam/resource/rest/". This path would be used for providing a resource for describing the additional resources published by the application, such as WADL or an AtomPub Service Description. This works fine under RESTEasy's own bootstrapper, without the Seam configuration handling.
