此页面调用以br为前缀的XML名称空间，但不存在taglibrary(This page calls for XML namespace declared with prefix br but no taglibrary exists)

 我刚刚完成了Netbeans对Hibernate教程的介绍（ http://netbeans.org/kb/docs/web/hibernate-webapp.html#01 ），我收到以下错误：“此页面调用用前缀声明的XML名称空间但是没有标签库存在“ 
 

 现在，我在其他地方看到了一个类似的问题： http : //forums.sun.com/thread.jspa?threadID=5430327但答案没有在那里列出。 或者，如果是，那么我显然会错过它 - 将我的index.xhtml文件中的一行写成“ http://www.w3.org/1999/xhtml ”。 它也不能解释为什么，当我重新加载localhost：8080时，消息消失。 
 

 这是我的index.xhtml文件： 
 

<html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:h="http://java.sun.com/jsf/html"
  xmlns:ui="http://java.sun.com/jsf/facelets"
  xmlns:f="http://java.sun.com/jsf/core">
    <ui:composition template="./template.xhtml">
        <ui:define name="body">
            <h:form>
                <h:commandLink action="#{filmController.previous}" value="Previous #{filmController.pageSize}" rendered="#{filmController.hasPreviousPage}"/>
                <h:commandLink action="#{filmController.next}" value="Next #{filmController.pageSize}" rendered="#{filmController.hasNextPage}"/>
                <h:dataTable value="#{filmController.filmTitles}" var="item" border="0" cellpadding="2" cellspacing="0" rowClasses="jsfcrud_odd_row,jsfcrud_even_row" rules="all" style="border:solid 1px">
                    <h:column>
                        <f:facet name="header">
                            <h:outputText value="Title"/>
                        </f:facet>
                        <h:outputText value="#{item.title}"/>
                    </h:column>
                    <h:column>
                        <f:facet name="header">
                            <h:outputText value="Description"/>
                        </f:facet>
                        <h:outputText value="#{item.description}"/>
                    </h:column>
                    <h:column>
                        <f:facet name="header">
                            <h:outputText value=" "/&t;
                        </f:facet>
                        <h:commandLink action="#{filmController.prepareView}" value="View"/>
                    </h:column>
                </h:dataTable>
                <br/>
                </h:form>
            </ui:define>
        </ui:composition>
    </html>


I just finished the Netbeans introduction to Hibernate tutorial ( http://netbeans.org/kb/docs/web/hibernate-webapp.html#01 ) and I am getting the following error: "This page calls for XML namespace declared with prefix br but no taglibrary exists"
 

Now, I have seen a similar question somewhere else: http://forums.sun.com/thread.jspa?threadID=5430327 but the answer is not listed there. Or, if it is, then I am clearly missing it -- line one of my index.xhtml file reads "http://www.w3.org/1999/xhtml". It also does not explain why, when I reload localhost:8080, the message disappears.
 

Here is my index.xhtml file:
 

<html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:h="http://java.sun.com/jsf/html"
  xmlns:ui="http://java.sun.com/jsf/facelets"

    <ui:composition template="./template.xhtml">
        <ui:define name="body">

                <h:commandLink action="#{filmController.previous}" value="Previous #{filmController.pageSize}" rendered="#{filmController.hasPreviousPage}"/>
                <h:commandLink action="#{filmController.next}" value="Next #{filmController.pageSize}" rendered="#{filmController.hasNextPage}"/>
                <h:dataTable value="#{filmController.filmTitles}" var="item" border="0" cellpadding="2" cellspacing="0" rowClasses="jsfcrud_odd_row,jsfcrud_even_row" rules="all" style="border:solid 1px">
                    <h:column>
                        <f:facet name="header">
                            <h:outputText value="Title"/>
                        </f:facet>
                        <h:outputText value="#{item.title}"/>
                    </h:column>
                    <h:column>
                        <f:facet name="header">
                            <h:outputText value="Description"/>
                        </f:facet>
                        <h:outputText value="#{item.description}"/>
                    </h:column>
                    <h:column>

                        </f:facet>
                        <h:commandLink action="#{filmController.prepareView}" value="View"/>
                    </h:column>
                </h:dataTable>
                <br/>
                </h:form>
