Hi Gary The thing is that JAX-RS does not allow for checking on the multiple root resource classes - I think there was a discussion on cxf users list about extending the selection algorithm - I don't mind if it would actually make things simpler.
Please see few more comments prefixed with S.B below. Particularly I don't understand why the use of subresources affects the complexity of response objects Thanks, Sergey -----Original Message----- From: Tong, Gary [mailto:gary.t...@morganstanley.com] Sent: 12 July 2009 11:52 To: dev@cxf.apache.org Subject: RE: JAX-RS Request Matching Wierdness Hi Sergey, The problems come up in a number of situations, all involving multiple service beans. The simplest case is the following: public class AWebService { @GET @Path("/a") public String a() { return "a"; } } public class BWebService { @GET @Path("/b") public String b() { return "b"; } } One of the two will work, but not both. This is of course the simplest case, but there are a number of other more concrete use cases that cause issues. For instance, if I had the following URLs: GET /user POST /user GET /user/search?params And I wanted to put the CRUD ops on UserWebService but the search stuff on a SearchWebService that uses @Path("/{type}/search") then that wouldn't work in CXF. > S.B : Try @Path("/user") public class UserService {} @Path("/user/") public class SearchService {} > S.B : - note the trailing '/' in SearchService. It might do the trick in other cases too Also, for instance if I had the following urls: GET /posts GET /user GET /user/{id}/posts /posts would go on PostWebService and /user would go on UserWebService, but if I wanted PostWebService to handle /user/{id}/posts as just a specialized version of /posts that would be tricky with CXF. It's doable with sub-resource locators, but then my response objects start getting complicated. > S.B : I'm not quite sure why the use of subresources affects the complexity of the response objects. Can you give an example please ?

FYI, it is the map that sorts resource classes according a number of criteria. Another thing is that the JAX-RS selection algorithm does not have be implemented literally the way it's documented in the spec, rather the final result should be correct. So let me know please what exactly is happening in your case Thanks, Sergey -----Original Message----- From: Tong, Gary [mailto:gary.t...@morganstanley.com] Sent: 11 July 2009 16:57 To: dev@cxf.apache.org Subject: JAX-RS Request Matching Wierdness Hello, Hey guys, just fyi, CXF's jax-rs doesn't do request matching correctly. According to JSR 311 in section 3.7.2, the jax-rs server is supposed to apply a series of steps to determine which URL to use for the request. Instead, CXF applies a path filter at the class level, and then returns the first entry it finds. Specifically the code that does this is in JAXRSUtils.selectResourceClass: if (!candidateList.isEmpty()) { Map.Entry<ClassResourceInfo, MultivaluedMap<String, String>> firstEntry = candidateList.entrySet().iterator().next(); values.putAll(firstEntry.getValue()); return firstEntry.getKey(); } Not sure if you guys know about this.
