Could you post the java code you use to start the process instance?

here it is

<java>
public static ClientResource getClientResource(String uri,String userName,String password) throws Exception {
System.out.println("in getClientResource password:"+password);
     ClientResource clientResource = new ClientResource(uri);
     ServiceUtil serviceUtil=new ServiceUtil();
     password=serviceUtil.decrypt(password);
     clientResource.setChallengeResponse(ChallengeScheme.HTTP_BASIC,userName, password);
     return clientResource;
}

public static String getRequestProcessId(String processKey,String userName,String password) throws ResourceException, Exception {
       String uri = REST_URI + "/process-definitions?size=100";
       System.out.println("key "+processKey);
       Representation response = getClientResource(uri,userName,password).get(MediaType.APPLICATION_JSON);
       JSONObject object = new JSONObject(response.getText());
       if (object != null) {
         JSONArray arr = (JSONArray) object.get("data");
         for (int i = 0; i < arr.length(); i++) {
           JSONObject jsonObject = (JSONObject) arr.get(i);
           if (jsonObject.get("key").equals(processKey)) {
             logger.info("Returning processDefinitionId " + jsonObject.get("id"));
             return (String) jsonObject.get("id");
           }
         }
       }
    return null;
}

public static String startRequestedProcess(HashMap<String,Object> param,String userName,String password)
      throws Exception {
      String uri = REST_URI + "/process-instance";
      JSONObject object=new JSONObject();
      Set s=param.keySet();
      Iterator<String> itr= s.iterator();
       while(itr.hasNext())
       { String key=itr.next();
        object.put(key, param.get(key));
        System.out.println(key +" "+param.get(key));
       }

      Representation rep = new JsonRepresentation(object);
      rep.setMediaType(MediaType.APPLICATION_JSON);
      JSONObject jsObj = new JSONObject(getClientResource(uri,userName,password).post(rep).getText());
      logger.info("Returning processId " + jsObj.getString("id"));
      return jsObj.getString("id");
}

</java>
