它显示了http 500与jasper错误，在启动应用程序时，我在同一个项目中使用了jersey和struts2。需要任何特定配置。尽管如此，所有jar文件都包含在内，它显示错误。

Answer 1

您正在显示页面而不通过Struts2过滤器。您需要调用Struts2操作，该操作将显示您的页面。

自Struts 2.1.3起，org.apache.struts2.dispatcher.FilterDispatcher也被弃用，因此如果您使用的是更高版本，则2.1.3将FilterDispatcher更改为org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter。

为什么不用这个过滤器拦截所有网址模式？将此过滤器<url-pattern>更改为<url-pattern>/*</url-pattern>。

在JSP中使用scriptlet的BTW是一种不好的做法，而是使用Struts2标签。

单个Web应用程序中的Struts2和Jersey会产生http 500错误
