Package org.json does not exist when importing org.json.JSONObject

Question

emacs 24.3.1 Fedora 20 jdk1.7.0_45

I created a java project using emacs and have the following project files and classpath:

.project

<?xml version="1.0" encoding="UTF-8"?> <projectDescription> <name>snaprequest</name> <comment></comment> <projects> </projects> <buildSpec> <buildCommand> <name>org.eclipse.jdt.core.javabuilder</name> <arguments> </arguments> </buildCommand> </buildSpec> <natures> <nature>org.eclipse.jdt.core.javanature</nature> </natures> </projectDescription> 

.classpath

 <?xml version="1.0" encoding="UTF-8"?> <classpath> <classpathentry kind="src" path="src"/> <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.6"/> <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/> <classpathentry kind="output" path="bin"/> </classpath> 

I have this version

In my java program, I want to use JSONObject, so I tried to import the following:

 import org.json.JSONObject; 

And when I try to compile on the command line, I get this error:

  error: package org.json does not exist import org.json.JSONObject; 

I know that I need to add something to my classpath so that it can find jar files, but I'm not sure how to do this?

Thanks so much for any suggestions,

The org.json.JSONObject class is available in json-20131018.jar. You need to download this jar and add this jar to the build path.

To add an external jar to the build path, you can - right-click on your project in eclipse - click build path → configure the build path - goto jump libraries - there you will find to add an external JAR

This will allow you to include any external jar in your build path.
