[ http://issues.apache.org/jira/browse/MYFACES-1148?page=comments#action_12446196 ] Philip Aston commented on MYFACES-1148: ---------------------------------------
Try setting save-sessions-enabled=false in weblogic.xml (http://edocs.bea.com/wls/docs92/webapp/weblogic_xml.html#wp1059284) This will prevent WebLogic from deserialising and reserialising the state when the web application is reloaded. This is roughly equivalent to Adam's suggestion. The cost is of course that the Faces initialization process will be required on each reload. > Weblogic Classloader problems during development (FactoryFinder) > ---------------------------------------------------------------- > > Key: MYFACES-1148 > URL: http://issues.apache.org/jira/browse/MYFACES-1148 > Project: MyFaces Core > Issue Type: Bug > Components: General > Affects Versions: 1.1.1 > Environment: Weblogic 9.0, 8.1, etc. Windows XP Pro sp2. > Reporter: Adam Brod > > Like most weblogic users, our team develops using the exploded war format. > That means that each time we deploy a new version of a class, weblogic > automatically picks it up. The way Weblogic implements this is that when it > detects a new class, it drops the classloader for that class, as well as the > Servlet and all helper classes that are loaded by the Servlet. That means > FacesServlet is dropped and reloaded. > The problem is that FactoryFinder stores the Factory classes in a Map where > the key is the current classloader. That works fine until I deploy a new > class to my webapp. At that point, weblogic drops the classloader and > creates a new one with the new class definition. Now when > FacesServlet.init() calls FactoryFinder.getFactory() (in the new > classloader), an IllegalStateException is generated (see below) because the > current classloader is not a valid key for the _registeredFactoryNames Map. > One possible solution that I can see to this is to change the key for the > Factory map to use the ServletContext's getServletContextName() as the key. > I am 95% sure this same problem exists in Weblogic 7.0, 8.1 and 9.1 since > they all use almost the same Servlet redeployment mechanism. I have only > tried this on Weblogic 9.0. > <Feb 20, 2006 5:38:07 PM EST> <Error> <HTTP> <BEA-101017> <[EMAIL PROTECTED] > - name: 'ma-web-1.0-SNAPSHOT > ', context-path: '/ma'] Root cause of ServletException. > java.lang.IllegalStateException: No Factories configured for this Application > - typically this is because a context listener is not setup in yo > ur web.xml. > A typical config looks like this; > <listener> > > <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class> > </listener> > at javax.faces.FactoryFinder.getFactory(FactoryFinder.java:84) > at javax.faces.webapp.FacesServlet.init(FacesServlet.java:84) > at > weblogic.servlet.internal.StubSecurityHelper$ServletInitAction.run(StubSecurityHelper.java:265) > at > weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321) > at > weblogic.security.service.SecurityManager.runAs(SecurityManager.java:121) > at > weblogic.servlet.internal.StubSecurityHelper.createServlet(StubSecurityHelper.java:61) > at > weblogic.servlet.internal.StubLifecycleHelper.createOneInstance(StubLifecycleHelper.java:58) > at > weblogic.servlet.internal.StubLifecycleHelper.<init>(StubLifecycleHelper.java:48) > at > weblogic.servlet.internal.ServletStubImpl.prepareServlet(ServletStubImpl.java:502) > at > weblogic.servlet.internal.ServletStubImpl.checkForReload(ServletStubImpl.java:429) > at > weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:221) > at weblogic.servlet.internal.TailFilter.doFilter(TailFilter.java:26) > at > weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:42) > at > oracle.adfinternal.view.faces.webapp.AdfFacesFilterImpl._invokeDoFilter(AdfFacesFilterImpl.java:367) > at > oracle.adfinternal.view.faces.webapp.AdfFacesFilterImpl._doFilterImpl(AdfFacesFilterImpl.java:336) > at > oracle.adfinternal.view.faces.webapp.AdfFacesFilterImpl.doFilter(AdfFacesFilterImpl.java:196) > at > oracle.adf.view.faces.webapp.AdfFacesFilter.doFilter(AdfFacesFilter.java:87) > at > weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:42) > at > org.apache.myfaces.component.html.util.ExtensionsFilter.doFilter(ExtensionsFilter.java:122) > at > weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:42) > at > weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.run(WebAppServletContext.java:3020) > at > weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321) > at > weblogic.security.service.SecurityManager.runAs(SecurityManager.java:121) > at > weblogic.servlet.internal.WebAppServletContext.securedExecute(WebAppServletContext.java:1925) > at > weblogic.servlet.internal.WebAppServletContext.execute(WebAppServletContext.java:1848) > at > weblogic.servlet.internal.ServletRequestImpl.run(ServletRequestImpl.java:1288) > at weblogic.work.ExecuteThread.execute(ExecuteThread.java:207) > at weblogic.work.ExecuteThread.run(ExecuteThread.java:179) > > -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
