406 Error for the Post JSON data to webserver in android?

Question

I am working for the crate application for the drupal based website.Here I face the problem for the post page from application to web server.

When I post the title and body then only title is appeared on server but body is not appeaerd.Here my body part into json format.

Below JSON format works perfectly into poster plugin of firefox,it successfully writes data to server, so now my question is to write android code for the same task.

{
 "type":"page",
 "title":"TITLE TESTING",
 "body":{
   "und":[
   {
    "value":"BODY TESTING"
   }
  ]
 }
}

I have tried like this:

 List<NameValuePair> params = new ArrayList<NameValuePair>();

    params.add(new BasicNameValuePair("type","page"));
    params.add(new BasicNameValuePair("title",title));
   params.add(new BasicNameValuePair("body", ""+jSONCategory.toString()));
 //  value of the jSONCategory.toString() : {"und":[{"value":"body_part"}]}

System.out.println("============@@@@@@@@@@@@@@@@@@@@@@@@@@@@@"+params);

when I print the value of the params then t display me like :

[type=page, title=title_part, body={"und":{"value":"body_part","format":"full_html"}]}]

And when I pass only the body part then it gives me status code 406 and for title it works perfect with 200 status code

Here my questions is how to pass string + json both combine to server. Here title part is String variable and body part is json variableenter code here

Thanks.

EDIT:

  JSONCategory = new JSONObject();
  JSONBody = new JSONObject();

 JSONObject Jsonvalue = new JSONObject();
                    Jsonvalue.put("value", body);

                    JSONArray jsonUnd = new JSONArray(); 
                    jsonUnd.put(Jsonvalue);

                    JSONCategory.put("und", jsonUnd);

                    JSONBody.put("type", "page");
                    JSONBody.put("title", title);
                    JSONBody.put("body", JSONCategory);

                    System.out
                            .println("WHOLE JSON OBJECT ====================>"
                                    + JSONBody.toString());

Logcat :

 WHOLE JSON OBJECT ====================>{"type":"page","body":{"und":[{"value":"body"}]},"title":"title"}

Use built in JSON API's instead of Lists. In your case, traversing from innermost object to the outermost object, it would look like this:

JSONObject j4=new JSONObject(); 
j4.put("value",test_value); 

JSONArray j3=new JSONArray(); 
j3.put(0,j4); 

JSONObject j2=new JSONObject(); 
j2.put("und",j3);

JSONObject j1=new JSONObject(); 
j1.put("type","page");
j1.put("title",title_string); 
j1.put("body",j2);

Then, j1.toString(); would give you your required json string for output.

Then you can use a standard HTTP POST to send it to the server (using threads to keep network code off your UI thread) like this:

protected void sendJson(JSONObject j1) {
        Thread t = new Thread(){
        public void run() {
                Looper.prepare(); //For Preparing Message Pool for the child Thread
                HttpClient client = new DefaultHttpClient();
                HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000); //Timeout Limit
                HttpResponse response;

                try{
                    HttpPost post = new HttpPost(URL);

                    StringEntity se = new StringEntity( j1.toString());  
                    se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
                    post.setEntity(se);
                    response = client.execute(post);
                    /*Checking response */
                    if(response!=null){
                        InputStream in = response.getEntity().getContent(); //Get the data in the entity

                }
                catch(Exception e){
                    e.printStackTrace();
                    createDialog("Error", "Cannot Estabilish Connection");
                }
                Looper.loop(); //Loop in the message queue
            }
        };
        t.start();      
    }
