    From the error it is obvious that the class com.jayway.jsonpath.PathNotFoundException not found com.jayway.jsonpath.PathNotFoundException

    Check if the JsonPath library is in the CLASSPATH . If it is missing, download its jar and put it in the CLASSPATH . Since you did not specify the version of JMeter and JSON Path Extractor, you may have to play around with the versions.

      Most likely you are trying to open a test plan of the third version of JMeter second. JSON Path support appeared only in 3.0, try the latest version.
