servlet 中的非 http 请求和响应
我正在使用 jboss 在 eclipse 中运行一个简单的 servlet。
当我部署时，我收到以下错误：
09:34:29,062 Servlet 的错误 [[ServletExample]] Servlet.service() ServletExample 抛出异常 javax.servlet.ServletException： 非 HTTP 请求或响应 javax.servlet.http.HttpServlet.service(HttpServlet.java:715) 在 org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) 在 org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) 在 org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) 在 org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) 在 org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) 在 org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:235) 在 org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) 在 org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:190) 在 org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:92) 在 org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.process(SecurityContextEstablishmentValve.java:126) 在 org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.invoke(SecurityContextEstablishmentValve.java:70) 在 org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) 在 org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) 在 org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:158) 在 org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) 在 org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:330) 在 org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:829) 在 org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:598) 在 org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) 在 java.lang.Thread.run（来源不明）
