Struts2和Tomcat

我想在Tomcat 7上使用Struts2框架创建一个新的应用程序。我在eclipse中创建了正确的项目。我从eclipse本身运行tomcat。我的应用程序启动了，但我在控制台中看到一个很长的异常跟踪（如下所示）。奇怪的是，这些显示为警告。最初，我以为我错过了一些库，所以我下载了jaxb-xjc，但是这并没有解决问题。我尝试的下一件事是将示例war文件（struts2-showcase.war）放入webapps文件夹并启动tomcat。日志仍然显示这些错误。任何投入都会很好。Struts2和Tomcat

您需要升级到最新的Tomcat 7.0.x版本，这些警告消失。

Tomcat正在扫描注释并找到对不可用类的引用。没事儿。然而，与其忽视它并继续进行，旧的Tomcat 7版本记录了一个错误。
