java - Jboss 为 ServletActionContext 类抛出 ClassNotFoundExpection？

Question

我有一个 struts 应用程序，可以在其中获取我正在使用此代码的 servlet 上下文

ServletContext servletContext = ServletActionContext.getServletContext();

这会在 tomcat 中返回我的 servletcontext，但是当我对 jboss AS 7 使用相同的代码时，它会抛出 ClassNotFoundException。但是struts jar文件已经在jboss模块中了。我不知道为什么会出现这个错误。

任何人都可以帮助我，如何在 jboss AS 7 服务器的操作类中获取 servletcontext 。
