Hi,
I am currently having trouble with getting the DELETE method to work
correctly. This may be due to my misunderstanding of the semantics for
DELETE so let me describe my scenario.
I currently have a resource with the following code snipped deployed on
Tomcat.
@DELETE
@Path("/removeUserSocialIdentity")
@Consumes({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public String removeUserSocialIdentity(UserSocialIdentityList
userSocialIdentityList) {
logger.debug("removeUserSocialIdentity");
return "OK";
}
I am trying to access this resource via the client API as follows.
UserSocialIdentityList userSocialIdentityList = new
UserSocialIdentityList();
Set<UserSocialIdentity> userSocialIdentitySet = new
HashSet<UserSocialIdentity>();
UserSocialIdentity userSocialIdentity = new UserSocialIdentity();
userSocialIdentity.setUserUID("b5c587fe030377730010d4482d6148ea");
Set<SocialIdentity> socialIdentitySet = new HashSet<SocialIdentity>();
SocialIdentityList socialIdentityList = new SocialIdentityList();
SocialIdentity socialIdentity = new SocialIdentity();
socialIdentity.setTypeCode("FACEBOOK");
socialIdentity.setUid("f1c5c6f8030377730010d4482c0f5d03");
socialIdentitySet.add(socialIdentity);
socialIdentity = new SocialIdentity();
socialIdentity.setTypeCode("TWITTER");
socialIdentity.setUid("c1c5c6f8030377730010d4482c0f5d03");
socialIdentitySet.add(socialIdentity);
socialIdentity = new SocialIdentity();
socialIdentity.setTypeCode("MYSPACE");
socialIdentity.setUid("a1c5c6f8030377730010d4482c0f5d03");
socialIdentitySet.add(socialIdentity);
socialIdentityList.setSocialIdentitySet(socialIdentitySet);
userSocialIdentity.setSocialIdentityList(socialIdentityList);
userSocialIdentitySet.add(userSocialIdentity);
userSocialIdentity = new UserSocialIdentity();
userSocialIdentity.setUserUID("b5c587fe030377730010d4482d6148ea");
socialIdentitySet = new HashSet<SocialIdentity>();
socialIdentityList = new SocialIdentityList();
socialIdentity = new SocialIdentity();
socialIdentity.setTypeCode("FACEBOOK");
socialIdentity.setUid("f1c5c6f8030377730010d4482c0f5d03");
socialIdentitySet.add(socialIdentity);
socialIdentity = new SocialIdentity();
socialIdentity.setTypeCode("TWITTER");
socialIdentity.setUid("c1c5c6f8030377730010d4482c0f5d03");
socialIdentitySet.add(socialIdentity);
socialIdentity = new SocialIdentity();
socialIdentity.setTypeCode("MYSPACE");
socialIdentity.setUid("a1c5c6f8030377730010d4482c0f5d03");
socialIdentitySet.add(socialIdentity);
socialIdentityList.setSocialIdentitySet(socialIdentitySet);
userSocialIdentity.setSocialIdentityList(socialIdentityList);
userSocialIdentitySet.add(userSocialIdentity);
userSocialIdentityList.setUserSocialIdentity(userSocialIdentitySet);
String response =
wr.path("removeUserSocialIdentity")
.type(MediaType.APPLICATION_JSON_TYPE)
.accept(MediaType.TEXT_PLAIN)
.header("Version", "1.0")
.put(String.class, userSocialIdentityList);
assertTrue("Method: removeUserSocialIdentity \nMessage: Something wrong,
the returned " +
"response is not 'OK'", response.equals("OK"));
This yields the following exception.

If I change the resource to accept PUT and change the client to make a PUT
request instead of the DELETE it works perfectly. I already changed the
client to use the Apache HTTP client so I can have a response with DELETE
but I still can't seem to get past this issue. Any help would be greatly
appreciated.
Sincerely,
Jonathan
