[jboss-jira] [JBoss JIRA] (WFLY-2690) JSP/JSPX tags doesn't work with Wildfly CR1

JSP/JSPX tags doesn't work with Wildfly CR1 ------------------------------------------- Key: WFLY-2690 URL: https://issues.jboss.org/browse/WFLY-2690 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: Web (Undertow) Affects Versions: 8.0.0.CR1 Environment: OpenJDK Runtime Environment (fedora-2.4.3.0.fc18-x86_64 u45-b15) OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode) Reporter: Otávio Garcia Assignee: Jozef Hartinger My app works fine on JBoss AS 7.1. When I migrate to Wildfly 8.0.0 CR1, my JSP tags don't work as expected. My project is a EAR with WAR module. When app starts, in the 1st access to page A, tag file is compiled and the page are rendered fine. But when I access another page (B in example), I got this error: org.apache.jasper.JasperException: java.lang.ClassCastException: org.apache.jsp.tag.web.default_tagx cannot be cast to org.apache.jsp.tag.web.default_tagx If I restart Wildfly and try to access page B, works fine. But when I access page A, I got the same error. My default.tagx is bellow: <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:html="http://www.w3.org/1999/xhtml" version="2.2"> <jsp:output doctype-root-element="HTML" doctype-system="about:legacy-compat" omit-xml-declaration="yes" /> some code <jsp:doBody /> more code </jsp:root> And the pages are somethink like this: <tags:default xmlns:tags="urn:jsptagdir:/WEB-INF/tags" xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:html="http://www.w3.org/1999/xhtml"> <jsp:output omit-xml-declaration="yes" /> my code here </tags:default> I was created a new empty project with two pages and one tagfile. The error don't occurs. But when I add CDI capabilities, the error occurs. There are something in CDI that confuses Jastow? As discussed here: https://community.jboss.org/message/850730
