[seam-issues] [JBoss JIRA] Commented: (SEAMFACES-158) URLRewriting in ViewConfig does not work in Tomcat/Servlet Container

URLRewriting in ViewConfig does not work in Tomcat/Servlet Container -------------------------------------------------------------------- Key: SEAMFACES-158 URL: https://issues.jboss.org/browse/SEAMFACES-158 Project: Seam Faces Issue Type: Bug Components: URL Rewriting Affects Versions: 3.0.1 Reporter: Lincoln Baxter III Fix For: 3.0.2 Hello i am using jsf 2, pretty 3.2.1 seam-faces 3.0.1, weld 1.1.0, and tomcat 7.0.11. If i use only pretty faces (without seam-faces) everything works. Also if i only use seam-faces (without pretty faces)everything works. But if i use those two together everythings fails on startup. I was looking at the source code and i found this: At startup i get this message from weld: INFO: Tomcat detected, CDI injection will be available in Servlets and Filters. Injection into Listeners is not supported And i guess that is fine because i am in servlet. But then: There is a class in seam-faces: {code}(a)Requires("com.ocpsoft.pretty.faces.spi.ConfigurationProvider") public class RewriteConfiguration implements ConfigurationProvider { public static final String PRETTYFACES_CONFIG_SERVLETCONTEXT_KEY = "org.jboss.seam.faces.com.ocpsoft.pretty.faces.spi.ConfigurationProvider"; @Override public PrettyConfig loadConfiguration(ServletContext sc) { WebXmlParser webXmlParser = new WebXmlParser(); try { webXmlParser.parse(sc); } catch (IOException ex) { throw new RuntimeException(ex); } catch (SAXException ex) { throw new RuntimeException(ex); } BeanManager beanManager = (BeanManager) sc.getAttribute(BeanManagerServletContextListener.BEANMANAGER_SERVLETCONTEXT_KEY); ViewConfigStore store = BeanManagerUtils.getContextualInstance(beanManager, ViewConfigStore.class);{code} Which is dependant on the presence of pretty-faces. It tries to get the beanManager from the servlet context under the key know as BeanManagerServletContextListener.BEANMANAGER_SERVLETCONTEXT_KEY.But that key is not there, here is why: BeanManagerServletContextListener class: {code}public class BeanManagerServletContextListener implements ServletContextListener { public static final String BEANMANAGER_SERVLETCONTEXT_KEY = "org.jboss.seam.faces.javax.enterprise.spi.BeanManager"; @Inject private BeanManager beanManager; public void contextDestroyed(ServletContextEvent sce) { } public void contextInitialized(ServletContextEvent sce) { sce.getServletContext().setAttribute(BEANMANAGER_SERVLETCONTEXT_KEY, beanManager); } }{code} This class tries to inject beanmanager. But this is a listener so injections don't work in servlet containers (tomcat). So this class always stores null reference under the key BEANMANAGER_SERVLETCONTEXT_KEY. And then somwhere else along the way stuff explodes with null pointer exception trying to obtain a reference to beanmanager. I described this on seam forums too here: http://seamframework.org/Community/SeamfacesWithTomcat But no body seams to read those forums at all. So i decided to try here :). This is related to pretty faces as well. I fixed it like this: I put the BeanManagerServletContextListener in my workspace and i change contextInitialized method into this: {code}public void contextInitialized(ServletContextEvent sce) { if (beanManager == null){ String name = Listener.class.getPackage().getName() + "." + BeanManager.class.getName(); beanManager = (BeanManager)sce.getServletContext().getAttribute(name); } sce.getServletContext().setAttribute(BEANMANAGER_SERVLETCONTEXT_KEY, beanManager); }{code} So now if the injection fails we try to get the bean manager from the listener. It is a hack, and don't think it will work on other servlets/cdi implementations but it is a place to start.
