Hi... JBoss 4.2.0 JDK 1.5.0_11 Windows XP I have just put a .war file into my "deploy" folder. When JBoss attempted to deploy, I got a very long stack trace of errors. The .war file is not mine... I don't know what it contains except that I know it is using ADF JavaServerFaces (adf-faces-impl-10_1_3_0_4.jar). The initial error is: 14:06:27,343 ERROR [[/ADFTest]] Exception sending context initialized event to listener instance of class org.jboss.web.jsf.integration.config.JBossJSFConfigureListener | java.lang.ClassCastException: com.sun.faces.application.ApplicationAssociate | at com.sun.faces.application.ApplicationAssociate.getInstance(ApplicationAssociate.java:172) | at com.sun.faces.config.JSFVersionTracker.publishInstanceToApplication(JSFVersionTracker.java:266) I have "googled" the error, and determined that one possible cause of this problem lies in the application.xml, where a reference to the .war filename has the wrong case (i.e. ADFTEST.war instead of ADFTest.war). There was such a reference, and I fixed it, but I still received the same error. Any direction at all on this one would be very helpful. Thanks in advance, Tonya View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4054050#...
