Обнаружена эта проблема, когда я попытался запустить tomcat 9.0 в eclipse neon.
Несколько дней назад я развернул несколько простых демоверсий, и tomcat мог работать хорошо. Но в эти дни я столкнулся с этой проблемой, когда пытался запустить страницу jsp или только пытался запустить tomcat в eclipse.
И еще несколько раз я мог перезапустить tomcat и снова запустить страницу jsp на сервере. Но в большинстве случаев я не мог успешно запустить tomcat.
Я не могу понять, почему эта ошибка произошла. . Я попытался повторно установить Tomcat, но не работаю :( я новичок на javaweb, пожалуйста, помогите мне решить эту проблемуНе удалось запустить tomcat в Eclipse neon
ГЗСА ошибки из консоли:.

«Вызванный:. java.lang.NoClassDefFoundError: орг/apache/commons/beanutils/Converter "- Где это будет, когда ваше приложение будет развернуто в Tomcat 9? – nitind
Спасибо за ваш комментарий. Я думаю, что org.apache.commons.beanutils.Converter.class находится на этом пути на моем компьютере (UserMVC02 - это имя моего webapp): /UserMVC02/lib/commons-beanutils-1.9.2.jar, внутри этого файла jar. В eclipse я добавил commons-beanutils-1.92.jar в путь сборки. – Chu
Привет, nitind: Я проверил для commons-beanutils.jar в папке/UserMVC02/lib /, и он присутствует там, затем я разворачиваю этот файл jar, я нашел Converter.class. – Chu
