Karl M. Davis created CXF-5980:
----------------------------------
Summary: JAX-RS 2.0 client: response.readEntity(new
GenericType<...>{}) fails with "unexpected element" UnmarshalException
Key: CXF-5980
URL: https://issues.apache.org/jira/browse/CXF-5980
Project: CXF
Issue Type: Bug
Components: JAX-RS
Affects Versions: 3.0.1
Environment: Ubuntu 14.04, Oracle Java 7
Reporter: Karl M. Davis
The following code fails:
{code:Java}
public List<GameSession> getGamesForPlayer() {
Client client = ClientBuilder.newClient();
Builder requestBuilder = client.target(config.getServiceRoot())
.path(IGameSessionResource.SERVICE_PATH)
.path(IGameSessionResource.SERVICE_PATH_GAMES_FOR_PLAYER)
.request(MediaType.TEXT_XML_TYPE);
cookieStore.applyCookies(requestBuilder);
Response response = requestBuilder.get();
if (Status.Family.familyOf(response.getStatus()) !=
Status.Family.SUCCESSFUL)
throw new HttpClientException(response.getStatusInfo());
List<GameSession> games = response.readEntity(
new GenericType<List<GameSession>>(GameSession.class)
{});
cookieStore.remember(response.getCookies());
return games;
}
{code}
With the following root exception (I'll attach the full log out/stack tracce so
you can see where in CXF this is coming from):
{code}
javax.xml.bind.UnmarshalException: unexpected element
(uri:"http://justdavis.com/karl/rpstourney/api/schema/v1";,
local:"gameSessions"). Expected elements are
<{http://justdavis.com/karl/rpstourney/api/schema/v1}account>,<{http://justdavis.com/karl/rpstourney/api/schema/v1}gameRound>,<{http://justdavis.com/karl/rpstourney/api/schema/v1}gameSession>,<{http://justdavis.com/karl/rpstourney/api/schema/v1}player>
... 93 common frames omitted
{code}
This is the first time I've tried to pull a generic/collection object out of a
Response using CXF's JAX-RS 2.0 client, so my guess is that this is just an
unsupported edge case? For what it's worth, the server-side of the web service
being queried is hosted by the same version of CSF and handles this just fine--
only the client seems to have issues.
