我已经编写了检票口应用程序，并且在本地运行良好。但是当我将它部署到 oracle 应用程序服务器（10g）时，我得到了这个错误：

我用 Wicket + Shiro

我应该怎么办？也许是因为我使用检票口过滤器？

看来您有一个需要 Wicket 1.4.x 的库，并且您使用的是 Wicket 1.5.x 或更高版本。

在您提供的堆栈跟踪中，它清楚地指出Objects来自 Wicket 的类没有使用 org.apache.wicket.util.lang.Objects.newInstance(Ljava/lang/String;)Ljava/lang/Object; 的方法

采用此方法的最后一个版本是 Wicket 1.4.x。

您不能将旧 Wicket 版本的库 jar 与较新的 Wicket 版本混合使用（反之亦然）。
