how to add json library to fedora14

Question

I am in need of the json package, these are the imports i need to resolve:

    import org.json.simple.JSONObject;
//import net.sf.json.JSONObject;
class json
{
    public static void main(String[] args)
    {
        JSONObject obj=new JSONObject();
        obj.put("name","foo");
        obj.put("num",new Integer(100));
        obj.put("balance",new Integer(1000));
        obj.put("is_vip",new Boolean(true));
        System.out.print(obj);
    }
}

i have downloaded the json package (json-simple-1.1.1.jar) from google code. Now i don't know how to install it in my fedora 14. I am using java version 1.6.0_20. Is there any specific version of json that i could download for this java version?

I have tried to execute it using the command

java -jar json-simple-1.1.1.jar

but i got a message showing

"Failed to load Main-Class manifest attribute from json-simple-1.1.1.jar"

You don't have to install it, you have to [include the jar in your classpath](http://stackoverflow.com/questions/2096283/including-jars-in-classpath-on-commandline-javac-or-apt) when running your application — BackSlash, Feb 14 '14 at 08:58
Copy the file into your lib folder inside your project or if you are using IDE(netbeans/eclipse) add it to jar libraries in your project properties — Sandeep, Feb 14 '14 at 09:01
@user3184228 Can you show us how are you running your application? — BackSlash, Feb 14 '14 at 09:07

You say you are running the application as

java json

Try specifying the jar in the classpath:

java -cp /path/to/json-simple-1.1.1.jar json

Where /path/to/json-simple-1.1.1.jar Is the path to the jar library

@user3184228 Can you update your question with the code you are trying to compile and run? – BackSlash Feb 14 '14 at 09:15
@user3184228 Are you running the command I wrote from the folder where `json.java` is? – BackSlash Feb 14 '14 at 09:20
yes both the code and the jar file are in the same folder – ambrosia1993 Feb 14 '14 at 09:31
