Java. Lang. classnotfoundexception: org. Apache. commons. Lang. Exception. nestableruntimeeffect

I used to use JSON technology when I was working on a project. However, at that time, the Project Manager configured all the preparations and provided the tools, I also told us how to use it. At that time, I just thought it was very useful and I did not study it.

Today, I wrote a JSON example. The following exception is reported when a call occurs:

Java. Lang. classnotfoundexception: org. Apache. commons. Lang. Exception. nestableruntimeexception

I searched the internet to find out that when I used JSON, I not only needed to import the JSON package, but also to import the other three packages.

In short, the following jars and JSON-lib must be used:
Commons-beanutils-1.7.0.jar
Commons-lang-2.1.jar
Ezmorph-1.0.2.jar
Json-lib-1.1-jdk15.jar
