Hi all! I tried to create a simple hello world type of JSF Web App just to test the JSF. My IDE is Eclipse Europa (3.3) J2EE version and I installed the JBoss Tools in it. When I try to deploy my simple web app (2 jsp:s, one managed bean, asks one's name and shows it on other page) I get this weird error during deployment: Exception sending context initialized event to listener instance of class org.jboss.web.jsf.integration.config.JBossJSFConfigureListener | java.lang.UnsupportedClassVersionError: Bad version number in .class file | Anyone else bumped into this? Thanks in advance! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4129054#...
