activemq Нет подходящего конструктора журнала

Question

это сводит меня с ума.Я просто пытаюсь запустить activemq на Mac OSX 10.5.7.У меня версия Java 1.5.0_19 и activemq 5.2.0.Ниже приведено исключение, которое я получаю при запуске bin/activemq.Кажется, не удалось найти log4j, что странно, учитывая, что он поставляется с activemq и определенно находится в каталоге lib/options.Единственное, о чем я могу думать, это о том, что у меня где-то конфликт, но я не представляю, как такое возможно.Если у кого-нибудь есть какие-либо советы, я внимательно слушаю, поиск в Google почти не дал результатов с той же ошибкой, и у одного человека, у которого есть точная ошибка, нет решения.

Answer 1

Итак, это определенно был конфликт с другим jar-файлом log4j.Я думаю, что, вероятно, мой плагин eclipse log4j был конфликтующим.Когда я удаляю log4j из activemq lib/optional, он работает.

Answer 2

Похоже, что исключение вызвано NoClassDefFoundError для org.apache.log4j.Category.Вы должны убедиться, что log4j jar находится на пути к классам.

Редактировать: Есть ли способ проверить стоимость ACTIVEMQ_CLASSPATH переменная?Если вы вызываете это через сценарий, который устанавливает переменную, вам, возможно, придется покопаться в сценарии, чтобы убедиться, что он добавляет все каталоги, которые, по вашему мнению, относятся к пути к классам.
