Usage

From source file:JSONPManager.java

/**
 * A convenience method to wrap a JSON string in a callback function name
 * used to support JSONP requests.//from  w  w  w  . jav  a  2s .  c  o  m
 * In this version the wrapped JSON is sent directly to the user via the PrintWriter
 * More information: http://en.wikipedia.org/wiki/JSON#JSONP
 *
 * @param json     the json string
 * @param callback the name of the callback method
 * @param writer   the PrintWriter to use to output the JSONP
 */
public static void wrapJSON(String json, String callback, java.io.PrintWriter writer) {
    // could do other more interesting things here, but for the moment let's keep it simple   
    writer.print(callback + "(" + json + ");");
