http://nagoya.apache.org/bugzilla/show_bug.cgi?id=12759 Problem with HttpSession in load test Summary: Problem with HttpSession in load test Product: Tomcat 3 Version: 3.3.1 Final Platform: Sun OS/Version: Solaris Status: NEW Severity: Blocker Priority: Other Component: Unknown AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Environment: Platform = SUN OS = Solaris Apache 1.3.12 Tomcat 3.3.1 Connector = mod_jserv AJP12 SSL = mod_ssl + OpenSSL Servlet 2.2 + JSP spec 1.1 Java Version 1.2 (Runtime & Dev) The problem appears only with load tests. It seems to have a confusion between the different sessions. To summarize, a sessionID corresponds to a login (that is to a user). For example, when a session is invalidated because the user sent a logout request, sometimes it occurs errors for an other user who is login yet and has normally a different sessionID. In fact, these two users have the same references to the session!! Here is the POST method in the servlet: //Retrieve the HTTP session from the request HttpSession session = request.getSession(); if (beanName.equals("loginBean") && httpMode.equals("secure")) { //Invalidate current session if (session.getAttribute("watchdog") == null) session.setAttribute("watchdog", watchdog); //to clean some directories related to the session session.invalidate(); //Create new session session = request.getSession(true); //Retrieve cookie from HTTP request Cookie[] cookies = request.getCookies(); cookies[0].setValue(session.getId()); cookies[0].setSecure(true); cookies[0].setPath(docRoot); //Add new cookie in HTTP response with secure option and new session ID response.addCookie(cookies[0]); //First abnormality if (session.getAttribute("watchdog") != null) Trace.println("[WMB_SERVLET]: Watchdog already bound to the session?? ", "ERROR", traceLevel); } Second abnormality: Here is the exception displayed sometimes during load tests with moreover the trace above: 09/11 17:09:32:135 java.lang.IllegalStateException: getAttributeNames: Session already invalidated at java.lang.Throwable.fillInStackTrace(Native Method) at java.lang.Throwable.fillInStackTrace(Compiled Code) at java.lang.Throwable.<init>(Compiled Code) at java.lang.Exception.<init>(Compiled Code) at java.lang.RuntimeException.<init>(RuntimeException.java:47) at java.lang.IllegalStateException.<init>(IllegalStateException.java:45) at org.apache.tomcat.facade.HttpSessionFacade.checkValid(Compiled Code) at org.apache.tomcat.facade.HttpSessionFacade.getAttribute(Compiled Code) at wmb.bean.protocole.Consult.serverProcess(Compiled Code) at wmb.servlet.WMBServlet.displayNextPage(Compiled Code) at wmb.servlet.WMBServlet.doGet(Compiled Code) at javax.servlet.http.HttpServlet.service(Compiled Code) at javax.servlet.http.HttpServlet.service(Compiled Code) at org.apache.tomcat.facade.ServletHandler.doService(Compiled Code) at org.apache.tomcat.core.Handler.invoke(Compiled Code) at org.apache.tomcat.core.Handler.service(Compiled Code) at org.apache.tomcat.facade.ServletHandler.service(Compiled Code) at org.apache.tomcat.facade.RequestDispatcherImpl.doForward(Compiled Code) at org.apache.tomcat.facade.RequestDispatcherImpl.forward(Compiled Code) at org.apache.jasper.runtime.PageContextImpl.forward(Compiled Code) at _default.fwd_consult_1._jspService(Compiled Code) at org.apache.jasper.runtime.HttpJspBase.service(Compiled Code) at javax.servlet.http.HttpServlet.service(Compiled Code) at org.apache.tomcat.facade.ServletHandler.doService(Compiled Code) at org.apache.tomcat.core.Handler.invoke(Compiled Code) at org.apache.tomcat.core.Handler.service(Compiled Code) at org.apache.tomcat.facade.ServletHandler.service(Compiled Code) at org.apache.tomcat.core.ContextManager.internalService(Compiled Code) at org.apache.tomcat.core.ContextManager.service(Compiled Code) at org.apache.tomcat.modules.server.Ajp12Interceptor.processConnection(Compiled Code) at org.apache.tomcat.util.net.TcpWorkerThread.runIt(Compiled Code) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(Compiled Code) at java.lang.Thread.run(Compiled Code) Here is javaBean Consult.java: public void serverProcess() { if(reload) { EmailParameters emailParameters = (EmailParameters)session.getAttribute("emailParameters"); …etc } } -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
