java .lang.NoClassDefFoundError: org / apache / poi / POIXMLTypeLoader при попытке изменить файл Word с помощью java

Question

привет, я пытаюсь изменить текстовый файл, используя java, но получаю сообщение об ошибке. Я использую eclipse jee ide. Я работаю над веб-проектом java. Я получаю ту же ошибку при попытке преобразовать файл docx в pdf
