Typed variable declaration : Class: JSONObject not found in namespace

Question

I am trying to execute below JSON code from Jmeter BeanShell Post processor but I am getting an error "Typed variable declaration : Class: JSONObject not found in namespace"

We are using JMeter 5.3 version and JSON jar files are available in the lib and lib\ext

import java.util.*;
import org.json.JSONObject;
import com.jayway.jsonpath.Criteria;
import com.jayway.jsonpath.Filter;
import com.jayway.jsonpath.JsonPath;


JSONObject cartItemsObj = (JSONObject) cartItems.get("C_cartItems");

log.info(cartItemsObj);

Error details:

In order to be able to use JSONObject class you need to have org.json.json library in JMeter Classpath
I fail to see where and how do you get cartItems object
Since JMeter 3.1 you are supposed to use JSR223 Test Elements and Groovy language for scripting
Groovy has built-in JSON support so if you want to get C_cartItems attribute value from the response (assuming that it exists on top level of the JSON you're getting from the server) it can be done as simple as:
```
cartItemsObj = new groovy.json.JsonSlurper().parse(prev.getResponseData()).C_cartItems

log.info(cartItemsObj)
```
