스레드 "main"의 예외 java.lang.NoClassDefFoundError : org/apache/thrift/transport/TTransportException

저는 Cassandra를 처음 사용하고 Eclipse에서 아래 프로그램을 사용하여 열과 수퍼 패밀리를 만들려고합니다 :스레드 "main"의 예외 java.lang.NoClassDefFoundError : org/apache/thrift/transport/TTransportException

내가 클래스 경로에있는 모든 헥터의 API를 항아리를 포함하고 난이 오류 원인을 모르는

나는 다음과 같은 예외가 프로그램을 실행하려고 . 누군가가 오류의 원인을 설명해 주시겠습니까?

classpath에'libthrift- .jar'이 있습니까? – Ralf

나는 이전에 t을 가지고 있지 않았다. 나는 클래스 패스에 놓았고 이제는 잘 작동한다. –
