No.. It is not proper way. Refer the steps,
For Classpath reference: Right click on project in Eclipse -> Buildpath -> Configure Build path -> Java Build Path (left Pane) -> Libraries(Tab) -> Add External Jars -> Select your jar and select OK.
For Deployment Assembly: Right click on WAR in eclipse-> Buildpath -> Configure Build path -> Deployment Assembly (left Pane) -> Add -> External file system -> Add -> Select your jar -> Add -> Finish.
This is the proper way! Don't forget to remove environment variable. It is not required now.
Try this. Surely it will work. Try to use Maven, it will simplify you task.

... @ Kruti It may because of duplicate packages. As error triggers that android had inbuilt json library with same package name so it is conflict.If you still want to use your own built library just change the package name of your library.

Hi all,
I am working with a JSON object and when I launch my project I get the following error:
java.lang.NoClassDefFoundError: org/json/JSONObject
viewmodels.LaunchViewModel.buildNextLaunch(LaunchViewModel.java:64)Looking at line 64...
JSONObject jsonObj = new JSONObject(getHTML("..."));Looks like I have not setup the dependencies correctly. I am working with IntelliJ with Gradle and I have imported JSON into my external libraries as seen here...
https://i.imgur.com/8VqLFf9.jpg
and here...
https://i.imgur.com/MFupkXg.jpg
My question is does it need to be added to the build.gradle file? Here are my dependencies:
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.11'
testCompile group: 'junit', name: 'junit', version: '4.12'
}I think that may be the culprit? But I am still pretty new to this process so any pointers would be sweet.
Thanks!
Edit for mods: The two screenshots are of my external libraries, no code in those. I replaced the remaining screen shot with a code block. Thanks!

It seems that you possibly have a screenshot of code in your post NoClassDefFoundError: org/json/JSONObject in r/javahelp . Screenshots of code instead of actual code text is against the Code posting rules of /r/javahelp as is also outlined in the sidebar - Code posting. Never submit screenshots of code instead of code text! If you posted an image merely to illustrate something, kindly ignore this message and do not repost. Your post is still visible to others. I am a bot and cannot distinguish between code screenshots and other images. If you indeed did this wrong, please edit the post so that it uses one of the approved means of posting code. For small bits of code (less than 50 lines in total, single classes only), the default code formatter is fine (one blank line before the code, then 4 spaces before each line of code). Pastebin for programs that consist of a single class only Gist for multi-class programs, or programs that require additional files Github or Bitbucket repositories are also perfectly fine as are other dedicated source code hosting sites. Ideone for executable code snippets that use only the console Please do not reply to this message, because I am a bot. Talk-to-the-bot is the new talk-to-the-hand.

Add json jar to your classpath
or use java -classpath json.jar ClassName
Or add this to your maven pom.xml depedencies:
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20090211</version>
</dependency>

As of today (15th July 2020), you need to use latest maven repository as per below:
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20200518</version>
</dependency>
For any new version in the future, you can check it here:
- https://mvnrepository.com/artifact/org.json/json
Then simply replace 20200518 with latest new version value.

Download the Json jar from here and add it to the classpath. If its a web application then add its under lib's.

It is better to add a line to copy the JSON jar to your application's WEB-INF/lib instead of Tomcat lib as your application uses it, not tomcat itself

You need to provide json libraries in classpath when you run the application as well. Easiest way would be put them in your tomcat's lib folder put json-20160810.jar in lib of tomcat
