Why can not run jsf1.1 in JBoss-4.2.0.GA?

[yibodai2007]

I have made a simple jsf1.1 project by use jsf-1_1_01.zip download from sun website, and deployed in JBoss-4.2.0.GA. when it run, a ClassCastException was threw, error message is as follow:

10:18:23,342 ERROR [1]] 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 cannot be cast to com.sun.faces.application.ApplicationAssociate
at com.sun.faces.application.ApplicationAssociate.getInstance(ApplicationAssociate.java:172)

at org.jboss.web.jsf.integration.config.JBossJSFConfigureListener.contextInitialized(JBossJSFConfigureListener.java:69)

Now i just want to know whether JBoss-4.2.0GA support jSF1.1 or not.

JBoss 4.2.0 comes with JSF 1.2 (RI). No need to package it into your application again. Have look in the http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossWithJSFCDDL.

The solution is here
https://jira.jboss.org/jira/browse/JBAS-4426
I copy the solution from the link above

make sure that you do not have the same library twice.
I got the same error, because I had 2 different versions of the same library (jsf-impl.jar):
* one in my .war archive under WEB-INF/lib
* the other one in jboss-4.2.0.GA\server\default\deploy\jboss-web.deployer\jsf-libs

removing the library from my .war archive fixed it

I have prove this solution with my problem and I have resolved
good luck
