Запуск Java-апплета

Question

Я написал код для Java-апплета, и он скомпилирован и работает на Eclipse. Однако после того, как я отправил свои файлы на веб-сервер и попытался запустить апплет с использованием файла html, я получил исключение.

java.lang.reflect.InvocationTargetException

Ранее у меня были проблемы с запуском приложения Java с моим Firefox, и я думаю, что исправил это, потому что я без проблем запускал некоторые онлайн-приложения Java.

Кто-нибудь считает, что с моим кодом что-то не так?

Я думаю, что проблема связана с обработкой событий для списков и полей со списком.
