Ошибка с использованием Apache POI

Question

Ошибка с использованием Apache POI

1

Я создал инструмент поиска для поиска документов Word в выбранной папке для заданного ключевого слова и возврата имен файлов, содержащих ключевое слово. Ошибка, возможно, из-за того, что Apache я использовал Apache POI для чтения документов Word, однако при компиляции проекта я получаю следующую ошибку:

Почему я получаю эту ошибку?

edit: не было xbeans 2.20 в моем проекте, который имеет ту же версию с xmlbeans, но все еще получает ошибку, когда я добавил xbean.jar

Может быть, вы могли бы немного уточнить, что вы делаете, вместо того, чтобы просто выгружать много кода? Спасибо!

Попробуйте добавить еще один Jar- stax-api-1.0.1.jar который находится внутри ooxml-lib. Также

XML-BEANS compiled schema: Incompatible minor version - expecting up to 23, got 24 (schemaorg_apache_xmlbeans.system.sE130CAA0A01A7CDE5A2B4FEB8B311707.index) - code 3

Он показывает, что существует несоответствие версии.

Помещение обоих xmlbean и xbean одной и той же версии должно решить проблему.

Попробуйте поменять банку с правильной версией ..
у меня не было никакого файла xbean.jar в библиотеке. Теперь я добавил xbean.jar 2.20, который имеет ту же версию с xmlbeans. Выдает ту же ошибку снова
Обновите свое исключение в вопросе.
обновить до XMLBeans 2.3 или более поздней версии .. это определенно будет работать ..
