Ошибка загрузки WebappClassLoader в Tomcat

Question

Я попытался запустить Tomcat и развернуть мой webapp из NetBeans после добавления и настройки нового сервлета. Я получил следующее в журнале ошибок Tomcat:

Я использую NetBeans 6.8 и Tomcat 6.

Answer 1

Решение было перезапустить NetBeans и развернуть веб-приложение. Похоже на ошибку NetBeans.
