Alfresco 4.2.c rest api: create site giving error

Question

I am trying to create a site using alfresco 4.2.c rest api /alfresco/wcservice/api/sites (PUT) I am using admin user so no issues with permissions. I am able to create site successfully using the alfresco share UI

String objectToPost = "{\"shortName\":\"firm007\", \"title\":\"firm007\", \"description\":\"firm007\", \"visibility\":\"PRIVATE\", \"isPublic\":\"false\", \"sitePreset\":\"site-dashboard\"}";
        RestTemplate restTemplate = new RestTemplate();
        HttpHeaders headers = new HttpHeaders();
        HttpEntity<String> entity = new HttpEntity<String>(objectToPost,headers);

        String url = PRE_URL + "/alfresco/wcservice/api/sites"+"?alf_ticket="+ TICKET;
        String response = restTemplate.exchange(url,HttpMethod.POST, entity, String.class, new Object[] {}).toString();
        System.out.println("Created SITE response is =" + response);    

I am getting 500 Internal Server Error on client side code and on alfresco server, I am getting following stack traces.

please can you help solve this issue. I want to create an alfresco site, through a remote REST api call

Expression site.shortName is undefined on line 9, column 56 in org/alfresco/repository/site/site.lib.ftl.

The problematic instruction:

Java backtrace for programmers:

Answer 1

solved this little puzzler.

I had not added the content-type as "application/json" hence the request was barking up the wrong tree and going to ftl instead of json

following code works fine creating a site in alfresco.

    headers.set("Content-Type", "application/json");

        String objectToPost = "{\"shortName\":\"firm008\", \"title\":\"firm008\", \"description\":\"firm008\", \"visibility\":\"PRIVATE\", \"isPublic\":\"false\", \"sitePreset\":\"site-dashboard\"}";
    System.out.println(objectToPost);

    RestTemplate restTemplate = new RestTemplate();
    HttpHeaders headers = new HttpHeaders();
    **headers.set("Content-Type", "application/json");**

    HttpEntity<String> entity = new HttpEntity<String>(objectToPost,headers);

    String url = PRE_URL + "/alfresco/wcservice/api/sites"+"?alf_ticket="+ TICKET;
    String response = restTemplate.exchange(url,HttpMethod.POST, entity, String.class, new Object[] {}).toString();
    System.out.println("Created SITE response is =" + response);
