JBoss中的"javax.servlet.ServletException:非HTTP请求或响应"

Question

我的jboss在尝试运行我的应用程序时弹出了不合规定的错误(spring mvc).它部署好了,这个例外并没有告诉我什么有用,所以我真的不知道该怎么做.我无法调试,真的无能为力:

    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:

Answer 1

HttpServlet.service(ServletRequest, ServletResponse)当参数无法分别转换为HttpServletRequest和时,它会被抛出HttpServletResponse.

这意味着以下两件事之一:

• 参数类型错误(不太可能)或
• 某些过滤器正在使用这些类型的错误副本,加载了错误的类加载器(例如,如果您servlet-api-x.x.jar使用webapp 提供自己的副本).
