CNFE for a class implementing a taglib function ----------------------------------------------- Key: WFLY-1529 URL: https://issues.jboss.org/browse/WFLY-1529 Project: WildFly Issue Type: Bug Components: Web (Undertow) Affects Versions: 8.0.0.Alpha2 Reporter: Juergen Zimmermann Assignee: Stuart Douglas Fix For: 8.0.0.Beta1 I'm using the latest WildFly snapshot containing Undertow 1.0.0.Alpha19. When I implement a JSF taglib having 1 function, then I get the stacktrace below when the .war file is deployed. This feature works fine with EAP 6.1. The JSF function is implemented in de.shop.util.JsfFunctions and declared in WEB-INF/shop.taglib.xml as follows: <?xml version="1.0" encoding="UTF-8"?> <facelet-taglib xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facelettaglibary_2_2.xsd" version="2.2"> <namespace>http://shop.de</namespace> <function> <function-name>aktuellesDatum</function-name> <function-class>de.shop.util.JsfFunctions</function-class> <function-signature> java.util.Date aktuellesDatum() </function-signature> </function> </facelet-taglib> The stacktrace in the WildFly console: 12:25:16,832 SEVERE [javax.enterprise.resource.webcontainer.jsf.config] Critical error during deployment: : com.sun.faces.config.ConfigurationException: javax.faces.FacesException: de.shop.util.JsfFunctions from [Module "deployment.shop2.war:main" from Service Module Loader] at com.sun.faces.config.processor.FaceletTaglibConfigProcessor.processFunctions(FaceletTaglibConfigProcessor.java:642) [jsf-impl-2.2.0-jbossorg-2.jar:] at com.sun.faces.config.processor.FaceletTaglibConfigProcessor.processTagLibrary(FaceletTaglibConfigProcessor.java:325) [jsf-impl-2.2.0-jbossorg-2.jar:] at com.sun.faces.config.processor.FaceletTaglibConfigProcessor.process(FaceletTaglibConfigProcessor.java:270) [jsf-impl-2.2.0-jbossorg-2.jar:] at com.sun.faces.config.ConfigManager.initialize(ConfigManager.java:437) [jsf-impl-2.2.0-jbossorg-2.jar:] at com.sun.faces.config.ConfigureListener.contextInitialized(ConfigureListener.java:214) [jsf-impl-2.2.0-jbossorg-2.jar:] at io.undertow.servlet.core.ApplicationListeners.contextInitialized(ApplicationListeners.java:144) [undertow-servlet-1.0.0.Alpha19.jar:1.0.0.Alpha19] at io.undertow.servlet.core.DeploymentManagerImpl.deploy(DeploymentManagerImpl.java:158) [undertow-servlet-1.0.0.Alpha19.jar:1.0.0.Alpha19] at org.wildfly.extension.undertow.deployment.UndertowDeploymentService.start(UndertowDeploymentService.java:74) at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1942) at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1875) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) [rt.jar:1.7.0_21] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) [rt.jar:1.7.0_21] at java.lang.Thread.run(Thread.java:722) [rt.jar:1.7.0_21] Caused by: javax.faces.FacesException: de.shop.util.JsfFunctions from [Module "deployment.shop2.war:main" from Service Module Loader] at com.sun.faces.config.processor.AbstractConfigProcessor.loadClass(AbstractConfigProcessor.java:384) [jsf-impl-2.2.0-jbossorg-2.jar:] at com.sun.faces.config.processor.FaceletTaglibConfigProcessor.processFunctions(FaceletTaglibConfigProcessor.java:638) [jsf-impl-2.2.0-jbossorg-2.jar:] ... 12 more Caused by: java.lang.ClassNotFoundException: de.shop.util.JsfFunctions from [Module "deployment.shop2.war:main" from Service Module Loader] at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:196) [jboss-modules.jar:1.2.1.Final] at org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked(ConcurrentClassLoader.java:444) [jboss-modules.jar:1.2.1.Final] at org.jboss.modules.ConcurrentClassLoader.performLoadClassChecked(ConcurrentClassLoader.java:432) [jboss-modules.jar:1.2.1.Final] at org.jboss.modules.ConcurrentClassLoader.performLoadClass(ConcurrentClassLoader.java:374) [jboss-modules.jar:1.2.1.Final] at org.jboss.modules.ConcurrentClassLoader.loadClass(ConcurrentClassLoader.java:119) [jboss-modules.jar:1.2.1.Final] at java.lang.Class.forName0(Native Method) [rt.jar:1.7.0_21] at java.lang.Class.forName(Class.java:266) [rt.jar:1.7.0_21] at com.sun.faces.util.Util.loadClass(Util.java:301) [jsf-impl-2.2.0-jbossorg-2.jar:] at com.sun.faces.config.processor.AbstractConfigProcessor.loadClass(AbstractConfigProcessor.java:376) [jsf-impl-2.2.0-jbossorg-2.jar:] ... 13 more
