Using JSONObject In Java Programs

Json » on Feb 1, 2012 { 11 Comments } By Sivateja

Let us see how to use JSONObject in java program, files required..

Jars required to JSON in java program..

  • json-lib-2.2.2-jdk15.jar
  • ezmorph.jar
  • commons-lang.jar
  • commons-logging.jar
  • commons-beanutils.jar
  • ommons-collections.jar

you can download these jars from previous session

import net.sf.json.JSONObject;
public class JsonEx {

	public static void main(String args[])
	{
		JSONObject jo=new JSONObject();
		 jo.put("site","java4s.com");
		 jo.put("content","Java");
		 jo.put("TotalLinks",927);
		 System.out.println(jo);
	}

}

Key(s):

  • Make sure you must have all above jar files in your class path
  • Our java program must import net.sf.json.* package

Am not giving any example program for using JSONObject in servlets and using JSONObject in jsp, as its the same logic. Even in the struts too 🙂
