Wildfly 10.0.0.Final duplitates contents of <jsp-config><include-prelude> or <include-coda> directives in web.xml ----------------------------------------------------------------------------------------------------------------- Key: WFLY-6136 URL: https://issues.jboss.org/browse/WFLY-6136 Project: WildFly Issue Type: Bug Components: Web (Undertow) Affects Versions: 10.0.0.Final Environment: Ubuntu Linux 14.04 amd64 Reporter: Juanm Manuel Enrique Muñido Assignee: Stuart Douglas I have been successfully deploying an application on WildFly 8.2.1 and WildFly 9.0.2 versions with the following <jsp-config> directives in web.xml deployment descriptor: <jsp-config> <jsp-property-group> <description>header and footer settings</description> <url-pattern>/WEB-INF/view/*</url-pattern> <url-pattern>/WEB-INF/error/*</url-pattern> <include-prelude>/WEB-INF/jspf/header.jspf</include-prelude> <include-coda>/WEB-INF/jspf/footer.jspf</include-coda> </jsp-property-group> </jsp-config> This code fragment includes the contents of /WEB-INF/jspf/header.jspf at the beginning of each .jsp file and <include-coda>/WEB-INF/jspf/footer.jspf</include-coda> at the end of each .jsp file that matches the <url-pattern>. But when I try to deploy this application with the same deployment descriptor in WildFly 10.0.0.Final, the contents of /WEB-INF/jspf/header.jspf and /WEB-INF/jspf/footer.jspf are included twice in each .jsp file that matches the <url-pattern>. If I add another <url-pattern> line, then the contents of /WEB-INF/jspf/header.jspf and /WEB-INF/jspf/footer.jspf are included three times, and so on. Any suggestion about this issue? Is this a deployment descriptor issue or a configuration issue in the standalone.xml of WildFly 10.0.0.Final version?
