its all perfect! why is this happening? the same endpoint and JSON works in workbench but not in my java code:

REST API :

@RestResource(urlMapping='/RestTest/*')

global with sharing class restTestShyam {


@HttpPost  
  global static String testRest(String t1, String t2) {
     System.debug('TestVar1: '+T1);
     System.debug('TestVar2: '+T2); 
     //System.debug('TestVar2: '+testVar3);  
    return 'Shyam your test is working';
    }
}

My JavaCode to call it:

public void restPostExample4() {
    System.out.println("\n_______________ OUTPUT _______________");
    String uri = baseUri + "/services/apexrest/RestTest";
    try {
        // create the JSON object containing the new contact details.
        JSONObject applicant = new JSONObject();
        applicant.put("t1", "shyam");
        applicant.put("t2", "raju");
        System.out.println("JSON for retriving record from test:\n" + applicant.toString(1));

        // Construct the objects needed for the request
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(uri);
        httpPost.addHeader(oauthHeader);
        httpPost.addHeader(prettyPrintHeader);
        // The message we are going to post
        StringEntity body = new StringEntity(applicant.toString(1));
        body.setContentType("application/json");
        httpPost.setEntity(body);

        // Make the request
        HttpResponse response = httpClient.execute(httpPost);

        // Process the results
        int statusCode = response.getStatusLine().getStatusCode();
        if (statusCode == 201 || statusCode == 200) {
            String response_string = EntityUtils.toString(response.getEntity());
            JSONObject json = new JSONObject(response_string);
            System.out.println("Retrive Successful! Status code returned is " + statusCode);
            System.out.println("Response from RestTest: " + json);
            System.out.println("httpPOST: " + httpPost);
            // Store the retrieved data as follows.
            // eg.....
            // contactId = json.getString("id");
        } else {
            System.out.println("Retrive unsuccessful. Status code returned is " + statusCode);
            System.out.println(getBody(response.getEntity().getContent()));
            System.out.println("httpPOST: " + httpPost);
        }
    } catch (JSONException e) {
        System.out.println("Issue creating JSON or processing results");
        e.printStackTrace();
    } catch (IOException ioe) {
        ioe.printStackTrace();
    } catch (NullPointerException npe) {
        npe.printStackTrace();
    }
}

My Output:

_______________ OUTPUT _______________

JSON for retriving record on applicant from yesterday:
{
 "t1": "shyam",
 "t2": "raju"
}
Retrive unsuccessful. Status code returned is 400
[ {
  "message" : "Unexpected parameter encountered during deserialization: t1 at [line:2, column:9]",
  "errorCode" : "JSON_PARSER_ERROR"
} ]

httpPOST: POST https://XX.salesforce.com/services/apexrest/XX/v37.0/services/apexrest/RestTest HTTP/1.1
Program complete.

workbench output:

  • Workbench works, so it means there is something wrong in your Java code. I am not familiar with Java, but wondering if applicant.toString(1) should be applicant.toString()? – Raul Feb 12 '17 at 22:19

This certainly looks like a problem in your JSON serialization implementation in your Java program .

Assuming you are using JSON.simple imports like below

import org.json.simple.JSONObject;

The proper way to convert to JSON string would below

 StringEntity body = new StringEntity(applicant.toJSONString());

Alternatively use Jackson for faster JSON to string serializer
