Example 1 with JsonCreationException

the class EndpointUtil method generateJSONObject.

/**

 * so while the Map passed to this function may have ordered keys, the resulting
 * JSONObject is not ordered.

 * @param list
 *          The source list for the JSON object
 * @return a JSON object containing the all the key-value as parameter
 * @throws JsonCreationException
