You need to find out, what is your JSON object should be deserialized to. If it's just a JSONObject and you want to parse it manually:

@Consumes("application/json")
public String getResource(JSONObject obj) {
...
}

If it is some kind of custom object:

@Consumes("application/json")
public String getResource(CustomObj customObj) {
...
}

But then you should take care about marshalling/unmarshalling of that object to JSON by Jackson.
