Hello SEAM committers, gurus and users. I have the curious situation of deploying the SEAM 1.2.1 example: blog. The server.log exception follows. Jarscan shows the ApplicationImpl class to be in the JBOSS server jar: jsf-impl.jar. I must have the wrong jar but I do not know which jar that could be. Obviously, the ApplicationImpl class does not contain the target method: addELResolver. Thanks in advance and please advise, David. 2007-10-16 09:47:52,273 ERROR [org.apache.myfaces.webapp.StartupServletContextListener] Error initializing ServletContext java.lang.RuntimeException: java.lang.NoSuchMethodException: com.sun.faces.application.ApplicationImpl.addELResolver(javax.el.ELResolver) at org.jboss.seam.jsf.SeamApplication12.(SeamApplication12.java:46) at org.jboss.seam.jsf.SeamApplicationFactory.getApplication(SeamApplicationFactory.java:29) at org.apache.myfaces.config.FacesConfigurator.configureApplication(FacesConfigurator.java:414) at org.apache.myfaces.config.FacesConfigurator.configure(FacesConfigurator.java:130) OS: Windows XP JBOSS: 4.2.1.GA SEAM 1.2.1.GA IDE: Eclipse Europa View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4095703#...
