在Heroku上運行maven項目給出應用程序錯誤

我對Maven & Heroku完全陌生。我正在嘗試瞭解RESTful Web服務。因此，我在JAX-RS &中創建了一個示例Web應用程序，將其部署在Heroku中。當我在本地Tomcat 8上運行它時，示例web應用程序運行完美。但是，當我嘗試在Heroku上打開相同的Web應用程序時，它會給我提供應用程序錯誤。在Heroku上運行maven項目給出應用程序錯誤

這是我所得到的，當我在localhost:8080

運行它，但是當我嘗試運行在this相同的Web應用程序，它給了我下面的錯誤

我很確定我錯過了什麼，但我無法弄清楚什麼。

以下是我的index.jsp
