Need to insert json data from java rest Client

[Arnab Ganguly]

Hi

  I want to insert json data using simple REST Client. -d option of curl command does not work in REST Client.

My java code as below.


DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpPut putRequest = new HttpPut(
                    "http://localhost:8080/virgil/data/ericsson/emp/666?index=true");

            StringEntity inputEntity = new StringEntity("- d"+"{\"empname\":\"PriyaDarshini\",\"address\":\"Noida-126\",\"dob\":\"10-8-1987\","
                    + "\"designation\":\"Solution Integrator\",\"about\":\"Works for AT&T.\n. Currenly in sprintteam2.She likes to play cricket, .\"}");
            inputEntity.setContentType("application/json");
            putRequest.setEntity(inputEntity);

            HttpResponse response = httpClient.execute(putRequest);


and getting exception in virgil

I believe the newer version of DropWizard attempts to parse the JSON when the json content type is provided.  The stack is coming from dropwizard itself.

Can you try the same request without setting the content-type header?
