運行我有一個Tomcat 6服務器，我正在開發使用Java EE 5部分並不在Tomcat 6
兼容的REST Web服務的項目的NetBeans 6.9.1開發的。我成功部署了該項目，程序運行並在瀏覽器中收到一個網頁。現在該計劃的一部分工作。也就是說，我可以從網站訪問Java bean，我檢索數據並將其顯示在網頁上。
但我無法訪問Web服務。 Web服務是使用Java Enterprise Beans（EJB）實現的。服務器上是否缺少EJB或REST Web服務的庫？
這是我在頁面上看到的錯誤： HTTP status 404. Description: the requested resource is not available。可能是什麼問題？
這是我得到的NetBeans：
