问题描述
我刚刚完成了Netbeans Hibernate入门教程( http://netbeans.org/kb/docs/web/hibernate-webapp.html#01 ),出现以下错误:此页面要求使用前缀br声明但没有标记库的XML名称空间"
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"
现在,我在其他地方也看到了类似的问题: http://forums.sun.com/thread.jspa?threadID=5430327但答案未在此处列出.或者,如果是这样,那么我显然会丢失它-index.xhtml文件的第一行显示为" http://www.w3.org/1999/xhtml ".它也没有解释为什么当我重新加载localhost:8080时消息消失.
Now, I have seen a similar question somewhere else:http://forums.sun.com/thread.jspa?threadID=5430327but 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.
这是我的index.xhtml文件:
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"
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=" "/>
</f:facet>
<h:commandLink action="#{filmController.prepareView}" value="View"/>
</h:column>
</h:dataTable>
<br/>
</h:form>
</ui:define>
</ui:composition>
</html>
推荐答案
问题显然来自<br/>
标记,facelets试图将其解释为带有前缀的JSF/facelets标记.
The problem clearly comes from the <br/>
tag, and facelets is trying to interpret it as a JSF/facelets tag with a prefix.
如果遵循标准,则此标记应类似于此<br />
(斜杠前有一个空格).尝试这种方法,如果它不起作用,请尝试将其删除.
If we follow the standards, this tag should look like this <br />
(with a space before the slash). Try it that way, and if it doesn't work, try removing it.
这篇关于该页面要求使用前缀br声明的XML名称空间,但不存在标记库的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
