我有一个.war包部署到JBoss5的{jboss5}/server/default/deploy目录下，启动没有出现错误，但访问JSP页面的时候出现异常，如下：
2010-09-16 16:00:57,437 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/mm].[jsp]] (http-127.0.0.1-8080-1) Servlet.service() for servlet jsp threw exception

检查web.xml的配置发现有Filter如下：

<!-- Hibernate lazy config -->

	<filter>

		<filter-name>hibernateFilter</filter-name>

		<filter-class>

			org.springframework.orm.hibernate3.support.OpenSessionInViewFilter

		</filter-class>

	</filter>

	<filter-mapping>

		<filter-name>hibernateFilter</filter-name>

		<url-pattern>/*</url-pattern>

	</filter-mapping>

跟踪发现org.springframework.web.filter.OncePerRequestFilter中的doFilter()方法抛出异常，代码如下：

if (!(request instanceof HttpServletRequest) || !(response instanceof HttpServletResponse)) {

			throw new ServletException("OncePerRequestFilter just supports HTTP requests");

		}

打印其实例为：
request = org.apache.catalina.connector.RequestFacade
response = org.apache.catalina.connector.ResponseFacade
