ClassNotFoundException: org.json.JSONException

Question

I get the below exception even after having json.jar and commons-collections.jar in classpath. It fails exactly at the import statement for JSONException

open the json.jar you have, and look for the class org.json.JSONException — Sajan Chandran

That looks like a runtime error, not a compile error, so the build path probably doesn't help you. Do you have those jars in your classpath? That's what's used at runtime to find classes.

I had to add the jar to web module's classpath, i.e, WEB-INF/lib. I did this by selecting the jar from Web Libraries in Java EE Module dependencies, and so it overrides the MANIFEST classpath which is not cooperative with json

Put your JAR libraries into the WEB-INF/lib folder.
