so, was die Lösung für diesen Code ist.

Answer 1

Entfernen Sie struts2-portlet-plugin-2.3.28.jar aus dem Klassenpfad. Aber für die Lösung, Bibliotheken zu verwalten, können Sie Maven verwenden.

Siehe das Tutorial, das mit Maven erstellt wurde: Create Struts 2 Web Application Using Maven To Manage Artifacts and To Build The Application.
