standard valve / errors handling
Hello, it is my understanding that tomcat uses a valve to detect Throwables from webapp and redirect to error page. However, in some case, it seems impossible to redirect to error page: 68937425 [http-8081-Processor14] ERROR StandardWrapper[/intranet:webdav] - Servlet.service() for servlet webdav threw exception java.lang.NullPointerException Aug 17, 2007 9:11:36 AM org.apache.catalina.core.StandardHostValve custom SEVERE: Exception Processing ErrorPage[exceptionType=java.lang.Exception, location=/jsp/error.jsp] java.lang.IllegalStateException at org.apache.coyote.Response.reset(Response.java:296) at org.apache.catalina.connector.Response.reset(Response.java:642) at org.apache.catalina.connector.Response.reset(Response.java:908) at org.apache.catalina.core.StandardHostValve.custom(StandardHostValve.java:355) at org.apache.catalina.core.StandardHostValve.throwable(StandardHostValve.java:211) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:134) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:526) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:526) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:825) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processConnection(Http11Protocol.java:738) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:526) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) at java.lang.Thread.run(Thread.java:534) Problem: because of the valve problem, my jsp is not called.
