JAX-RS webservice using #Path("/") at class level fails on TomEE+ 1.5.1 - cxf

Question

This simple root resource class fails when running on TomEE+ 1.5.1, return is a 404 error "The requested resource is not available." It is packaged as a WAR with and empty web.xml file in WEB-INF.
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.UriInfo;
#Path("/")
#Produces({ "text/plain", "text/html", "text/xml", "application/xml", "application/json" })
public class BrokenResource {
private static final Log logger = LogFactory.getLog(BrokenResource.class);
public BrokenResource()
{
logger.info("constructed");
}
#GET
#Path("getloggedinguids")
public Response foo(#Context UriInfo uInfo)
{
return Response.ok("\n\n\nrequest URI = " + uInfo.getRequestUri()).build();
}
}
It deploys and I see these lines in the console output:
Mar 22, 2013 4:56:16 PM org.apache.openejb.server.rest.RESTService deployPojo
INFO: REST Service: http://localhost:8080/test//* -> Pojo BrokenResource
I have also tried packaging it with a web.xml that declares:
<servlet>
<servlet-name>test</servlet-name>
<display-name>Test OpenEJBRest Servlet</display-name>
<servlet-class>
org.apache.openejb.server.rest.OpenEJBRestServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>test</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
Same results as with an empty web.xml file.
I also tried changing the class level #Path annotation to #Path("*") and then I get a different response, in the console output I see the following line:
WARNING: No root resource matching request path /test/getloggedinguids has been found, Relative Path: /getloggedinguids.
Finally... if I change the #Path annotation to something like #Path("/foo") then that works exactly as expected... hitting /test/foo/getloggedinguids returns the request URI..
I've be trying all sorts of variations of servlet mapping versus class level annotations and one thing is consistent... a #Path("/") annotation at the class leve always fails.
I even grabbed an example from the "RESTful Java with JAX-RS book" that uses the #Path("/") at the class level... that also fails.
Is this a bug in the CXF implementation of the JAX-RS standard? My project requires that I use a stock TomEE+ container so I can't switch to another JAX-RS implementation :-(

Instead of adding entries into the web.xml, keep in mind TomEE has native support for JAX-RS if you use the JAX-RS or TomEE+ versions.
Add a class like this and remove your web.xml entries:
import java.util.Arrays;
import java.util.HashSet;
import java.util.Set;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
#ApplicationPath("/")
public class NoteTakerApplication extends Application {
#Override
public Set<Class<?>> getClasses() {
return new HashSet<Class<?>>(Arrays.asList(BrokenResource.class, RestExceptionMapper.class, OtherClassesYouMayHave.class));
}
}
