cannot print the Json-RPC Response

Question

I have a java webservice, that must return a response if the login is successful

The return line of the server side method is

    return new Response(new InfoSessionJson(newKey, is), null, id);

To get the response I have tried to use the code

HttpResponse response = mClient.execute(httppost);
HttpEntity entity = response.getEntity();
InputStream is = entity.getContent();
if(response != null){
        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
                StringBuilder sb = new StringBuilder();
                String line = null;
                loggato=true;
                try {
                     while ((line = reader.readLine()) != null) {
                     sb.append(line + "\n");
                }
                System.out.println("The response is "+sb.toString());

But the output print returns an apache error

I have tried to print the output of the

HttpEntity entity = response.getEntity();
    InputStream is = entity.getContent();

directly with

  System.out.print(entity);
  System.out.print(response);

and this print:

org.apache.http.conn.BasicManagedEntity@40575ac8 org.apache.http.message.BasicHttpResponse@40574a00

Where is the error??

I cannot parse the response correctly or the problem is before???

the webservice method has this fim

@Webservice(paramNames = {"email", "password", "stayLogged", "idClient"},
public Response startSession(String email, String password, Boolean stayLogged, String idClient)

and I send a json with

StringEntity stringEntity = new StringEntity(jsonObject.toString());
                    httpost.setEntity(stringEntity);
                    httpost.setHeader("Accept", "application/json");
                    httpost.setHeader("Content-type", "application/json");

Where the json object sent is

{"method":"startSession","params":[{"email":"test.web@yahoo.it","password":"1234","idClient":"ANDROID","stayLogged":"1"}]}

The webservice works fine with an iOS app but wont work with mine android app,

Where is the error in the procedure that I have described in this thread???

I hope someone can help me.

Answer 1

I should use the code

stringEntity.setContentEncoding(HTTP.UTF_8);

to set the encoding mode to UTF, with this, the server accept the json request and give the correct response

Answer 2

Try: System.out.println("The response is "+sb.toString());.

line is erased at each loop.

Answer 3

I have almost the exact same code and it works fine for me, maybe there is a issue with the request that you are sending. Look at the response status code to check for errors:

status = response.getStatusLine();
status_code = status.getStatusCode();

There may be some error on the server side causing you to get an empty 500 response or something.
