I am a new user of Restlet (and quite hapy with it, too), but I found that using the JSON classes that come with it do not work well enough for me. They do serialize basic classes, but do not work on things like HashMap, or really anything nested. I checked the main JSON website to see if there were newer versions of those classes (there are), but they still do not on nested objects.
JSON-Lib does work well for this, so I switched to using that. However, when I want to create a representation out of the new (JSON-Lib) JSONObject, it does not accept the type. Representation representation = new JsonRepresentation(json); The warning is: "Type safety: The expression of type JSONObject needs unchecked conversion to conform to Map<Object,Object>" The reason is because "json" is of type "net.sf.json.JSONObject" instead of "org.json.JSONObject". Ultimately, the best solution is for "net.sf.json.JSONObject" to extend "org.json.JSONObject", as is done with other JSON libraries I have tested, but I seriously doubt this is going to happen. I can "fix" the issue by doing this instead: Representation representation = new JsonRepresentation(json.toString()); It just seems wasteful to have a usable JSONObject, convert it to a string and then pass it to a constructor. Has anyone successfully used JSON-Lib with Restlet without resorting to a hack like this? Also, is there a reason that Restlet only works with the basic "org.json.*" library? I would think that JSONObject should be handled in the way logging is handled: you can use the basic built-in logging in the JDK, or use something else, like Log4J. Can this also be done with "org.json.*" and other JSON implementations, too? I very much would appreciate any replies / suggestions.
