"javax.servlet.ServletException:非HTTP请求或响应"在JBoss [英] "javax.servlet.ServletException: non-HTTP request or response" in JBoss

问题描述

我的jboss在尝试运行我的应用程序(spring mvc)时抛出了无法描述的错误.它可以正常部署，并且此异常不会告诉我任何有用的信息，因此我真的不知道该怎么办.我无法调试，无法真正做任何事情:

My jboss is throwing undescriptive error while trying to run my application (spring mvc). It deploys ok, and this exception doesn't tell me anything useful so I don't really know what to do. I can't debug , can't do anything really :

    13:00:01,262 INFO  [ServerImpl] JBoss (Microcontainer) [5.1.0.GA (build: SVNTag=JBoss_5_1_0_GA date=200905221053)] Started in 2m:13s:790ms

**Started successfully**

从浏览器运行应用程序时，会发生这种情况:

While running the application from the browser this happens :

推荐答案

当无法将参数分别强制转换为HttpServletRequest和HttpServletResponse时，将在HttpServlet.service(ServletRequest, ServletResponse)中抛出该错误.

This gets thrown in HttpServlet.service(ServletRequest, ServletResponse) when the parameters can't be cast to HttpServletRequest and HttpServletResponse respectively.

这意味着两件事之一:

• 参数的类型错误(不太可能)或
• 某些过滤器使用的是这些类型的错误副本，并带有错误的类加载器(例如，如果您通过Webapp交付了自己的servlet-api-x.x.jar副本).

• the parameters are of the wrong type (unlikely) or
• some filter is using the wrong copy of those types, loaded with a wrong classloader (for example if you deliver your own copy of servlet-api-x.x.jar with your webapp).
