Hello, After 2 months spent in EJB3 "wanderland", I have a prototype for my app. I think I am now "ready" to draft up a nice web user interface for it. With a clean JBoss 4.0.5GA and Seam 1.2.1GA and JSF 1.2 Sun RI, I created a rudimentary login page. Well, not too long into the task I realized I have to go through a few configurations before I could get Seam to load appropriately with Sun's JSF RI + Facelets (no Ajax involved yet). I tried to search for a posting that I found back sometimes in Feb 2007 referring to how to do such task yet I could not find it. :-( Can someone help locating this posting or perhaps pointing me to the right location? Thanks. FYI, the latest error I got is this: anonymous wrote : 14:35:24,234 ERROR [STDERR] java.lang.RuntimeException: java.lang.NoSuchMethodException: com.sun.faces.application.ApplicationImpl.addELResolver(javax.el.ELResolver) | 14:35:24,234 ERROR [STDERR] at org.jboss.seam.jsf.SeamApplication12.(SeamApplication12.java:46) | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4042651#...
