Struts2和Tomcat

我想在Tomcat 7上使用Struts2框架創建一個新的應用程序。我在eclipse中創建了正確的項目。我從eclipse本身運行tomcat。我的應用程序啓動了，但我在控制檯中看到一個很長的異常跟蹤（如下所示）。奇怪的是，這些顯示爲警告。最初，我以爲我錯過了一些庫，所以我下載了jaxb-xjc，但是這並沒有解決問題。我嘗試的下一件事是將示例war文件（struts2-showcase.war）放入webapps文件夾並啓動tomcat。日誌仍然顯示這些錯誤。任何投入都會很好。Struts2和Tomcat

您需要升級到最新的Tomcat 7.0.x版本，這些警告消失。

Tomcat正在掃描註釋並找到對不可用類的引用。沒事兒。然而，與其忽視它並繼續進行，舊的Tomcat 7版本記錄了一個錯誤。
