[jboss-user] [JBoss Portal] - a JSF Validator cannot be cast to javax.faces.validator.Vali

JBoss portal is using idenity portlet to register new users and edit profiles for existing users. I added a my own JSF validator to the identty portlet which when opened now throws the following exception: java.lang.ClassCastException: com.kachanov.test004.validators.MyValidator cannot be cast to javax.faces.validator.Validator at org.apache.myfaces.application.ApplicationImpl.createValidator(ApplicationImpl.java:613) The code of my validator is: ========================================================== package com.kachanov.test004.validators; import javax.faces.application.FacesMessage; import javax.faces.component.UIComponent; import javax.faces.context.FacesContext; import javax.faces.validator.Validator; import javax.faces.validator.ValidatorException; public class MyValidator implements Validator { public void validate(FacesContext arg0, UIComponent arg1, Object arg2) throws ValidatorException { System.out.println("testing this validator"); } } ========================================================== So please thell me how can it bee that a class that implements Validator cannot be cast to javax.faces.validator.Validator?????? Is in't it against basic design of Java language? I reported this to JIRA and got this answer: =============================== Not a bug. Please see classloading rules. It looks like your application embeds JSF libs, while they are already available in JBoss AS. =============================== But I have no idea where to look for solution View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4133519#...
