OmniFaces ClassNotFoundException CombinedResourceHandler

Question

Я пытаюсь получить BootsFaces, OmniFaces и PrimeFaces, работающих вместе с Tomcat 9:

Я также попытался использовать более старые версии OmniFaces, без успеха.

Answer 1

Ваш pom.xml не заполнен. Если вы использовали точно такой же pom.xml, как указано выше, вы получили простой файл jar вместо военного файла, а Maven не добавила ни одну из библиотек в папку WEB-INF/lib.

Чтобы исправить это, выполните следующие действия:

• задающие <packaging>.
• добавить плагин Maven war
• и - если вы используете Eclipse - укажите версию Java, которую вы хотите использовать. В противном случае Eclipse предполагает, что вы используете Java 1.5, который не будет работать с BootsFaces.

Кстати, вам не нужен CombinedResourceHandler. Это просто отличный инструмент для ускорения вашего приложения до прибытия http/2.

Ради удобства, вот полный работает pom.xml:
