Json object in java

Question

I am working in Eclipse. I want to use JSON object in my servlets, so I attached jar file in library for JSON.

Now it shows all JSON classes in intellisense, but it giving run time exception

java.lang.NoClassDefFoundError: org/json/JSONArray

Can somebody suggest me how can I resolve this exception?

Adding a jar to your build path in Eclipse isn't enough. The jar must be in the WEB-INF/lib directory for it to load at runtime, which if your project is set up as a Dynamic Web Project, automatically sets those jars on the build path.
