Hi Sanjay, The JAX-RS spec doesn't mandate any particular JSON serialization. From what I see the JSON provider shipped with Restlet/JAX-RS extension supports automatic serialization of Map instances and of Java beans. >From the JSONObject(Object bean) Javadocs:
* Construct a JSONObject from an Object using bean getters. * It reflects on all of the public methods of the object. * For each of the methods with no parameters and a name starting * with <code>"get"</code> or <code>"is"</code> followed by an uppercase letter, * the method is invoked, and a key and the value returned from the getter method * are put into the new JSONObject. * * The key is formed by removing the <code>"get"</code> or <code>"is"</code> prefix. If the second remaining * character is not upper case, then the first * character is converted to lower case. * * For example, if an object has a method named <code>"getName"</code>, and * if the result of calling <code>object.getName()</code> is <code>"Larry Fine"</code>, * then the JSONObject will contain <code>"name": "Larry Fine"</code>. Are you providing getters for your Item class?

Not sure if there is a simpler way...anyways :-) _____ From: [EMAIL PROTECTED] To: [email protected] Date: Tue, 5 Aug 2008 02:11:54 +0000 Subject: RE: JSON Set with JAXRS I looked at the restlet example of Employees and changed my code to return a ItemList<Item> and got back a better JSON response like: {"class":"class Item","items":["[EMAIL PROTECTED]","[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> "]} What should I do to get the same back with {[id:10, name=car, id:21, name=tank]}, i.e., json representation of Item. I would not like to override the toString() method of Item to be in JSON format. Would I need to create custom message body writer for the Item class? Thanks in advance. _____ From: [EMAIL PROTECTED] To: [email protected] Date: Tue, 5 Aug 2008 00:38:29 +0000 Subject: JSON Set with JAXRS Greetings, I am exploring Restlet's JAXRS support and trying the following in a Resource class: @GET @ProduceMime("application/json") public Set<Items> getItems() { .... return items; } When the call is made, the Resource is invoked, however the returned response is not a JSON formatted set but something like: {"empty":false,"class":"class java.util.HashSet"} Do I need to write some custom code to handle the mime type? I though JAXB, JSON etc were pretty much standard and I would have got back a JSON string like [[....] [....]]? Please let me know if I am missing something here.
