jsf - Using new xmlns.jcp.org namespace on composites causes java.lang.NullPointerException at java.util.concurrent.ConcurrentHashMap.putIfAbsent -

-

i reading java ee 7 tutorial http://docs.oracle.com/javaee/7/tutorial/doc/jsf-facelets005.htm#giqzr

after typed example code in chapter 8.5 composite components in ide , run example on glassfish4.0, got error

java.lang.nullpointerexception     @ java.util.concurrent.concurrenthashmap.putifabsent(concurrenthashmap.java:1078)     @ com.sun.faces.util.cache.get(cache.java:116)     @ com.sun.faces.application.view.faceletviewhandlingstrategy.getcomponentmetadata(faceletviewhandlingstrategy.java:237)     @ com.sun.faces.application.applicationimpl.createcomponent(applicationimpl.java:951)     @ javax.faces.application.applicationwrapper.createcomponent(applicationwrapper.java:648)

then check older version of tutorial, found difference.

in java ee 7 version email.xhtml code following:

<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en"   "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"   xmlns:composite="http://xmlns.jcp.org/jsf/composite"   xmlns:h="http://xmlns.jcp.org/jsf/html">  <h:head>     <title>this content not displayed</title> </h:head> <h:body>     <composite:interface>         <composite:attribute name="value" required="false"/>     </composite:interface>      <composite:implementation>         <h:outputlabel value="email id: "></h:outputlabel>         <h:inputtext value="#{cc.attrs.value}"></h:inputtext>     </composite:implementation> </h:body> </html>

but in java ee 6 version

<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en"   "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"   xmlns:composite="http://java.sun.com/jsf/composite"   xmlns:h="http://java.sun.com/jsf/html">  <h:head>     <title>this content not displayed</title> </h:head> <h:body>     <composite:interface>         <composite:attribute name="value" required="false"/>     </composite:interface>      <composite:implementation>         <h:outputlabel value="email id: "></h:outputlabel>         <h:inputtext value="#{cc.attrs.value}"></h:inputtext>     </composite:implementation> </h:body> </html>

after changed code java ee 6 version, error gone. difference namespace. don't know whether issue of tutorial. there knows?

the way how new xmlns.jcp.org xml namespaces been handled broken in first mojarra releases 2.2.0 , 2.2.1. has been fixed in mojarra 2.2.2 (note: ticket in link describes different problem symptom, under covers, it's same cause). it's recommended upgrade @ least mojarra 2.2.2 (always pick newest available, if possible). glassfish 4.0 has 2.2.0 bundled. can jar javaserverfaces.java.net. need replace javax.faces.jar file in glassfish's /modules folder newer version.

the java ee 7 tutorial fine. implementation broken. kind of trouble way not unusual first major glassfish release (all hastle ready on time). recommend wait java ee 7 until glassfish 4.0.1 or 4.1 has been brought out avoid future surprises. note other vendors apache tomcat , jboss take time release java ee 7 container; don't have production ready version yet.
