IdentityRequestWrapper should not always create a new Http Session ------------------------------------------------------------------- Key: JBSEAM-4736 URL: https://jira.jboss.org/browse/JBSEAM-4736 Project: Seam Issue Type: Bug Components: JSF Integration Affects Versions: 2.1.2.GA Environment: Redhat Linux Entreprise 4.6, Java 1.5, JBoss 4.3 Reporter: Gerard COLLIN Priority: Optional We have on production a Seam / Icefaces application. This application is used during the day by users to enter some data. The same application is used during the night to run some batches. These batches are run using Web Services, that starts Seam and run EJB3 stateless sessions beans. 010-11-19 00:16:36,520 ERROR [org.apache.catalina.core.ContainerBase] "Servlet.service()" pour la servlet WsServlet a g?n?r? une exception java.lang.IllegalStateException: Cannot create a session after the response has been committed at org.apache.catalina.connector.Request.doGetSession(Request.java:2282) at org.apache.catalina.connector.Request.getSession(Request.java:2064) at org.apache.catalina.connector.RequestFacade.getSession(RequestFacade.java:833) at org.apache.catalina.connector.RequestFacade.getSession(RequestFacade.java:844) at org.jboss.seam.web.IdentityRequestWrapper.<init>(IdentityRequestWrapper.java:23) at org.jboss.seam.web.IdentityFilter.doFilter(IdentityFilter.java:40) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.web.RedirectFilter.doFilter(RedirectFilter.java:45) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.servlet.SeamFilter.doFilter(SeamFilter.java:158) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:230) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:173) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:182) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:433) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:104) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:241) at org.apache.coyote.ajp.AjpProcessor.process(AjpProcessor.java:437) at org.apache.coyote.ajp.AjpProtocol$AjpConnectionHandler.process(AjpProtocol.java:381) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:595) I really don't understand why this error occurs, because we are in a filter, but looking at the code in IndentityRequestWrapper, I see: public IdentityRequestWrapper(HttpServletRequest request) { super(request); identity = (Identity) request.getSession(). getAttribute(Seam.getComponentName(Identity.class)); } ==> Notice the getSession(), that forces creation of a new session. I think a better idea is to call getSession(false), so that no session gets created as a side effect?
