[英]<my:foo> Tag Library supports namespace: http://java.sun.com/jsf/composite/mycomponents, but no tag was defined for name: foo
[英]NETBEANS 7.4: “no tag was defined for name: register” + “No library found for namespace http://java.sun.com/jsf/composite/my_composite_component”
我在Linux Mint 13 Maya上使用Netbeans 7.4。 我學習了如何編寫一個簡單的JSF復合組件。 但是我有一些錯誤:
當我嘗試啟動我的應用程序時:
<my_composite_component:register> Tag Library supports namespace: http://java.sun.com/jsf/composite/my_composite_component, but no tag was defined for name: register
當我嘗試使用我的組件時:
“No library found for namespace http://java.sun.com/jsf/composite/my_composite_component”
這是我的Netbeans項目中目錄的結構:
和代碼:
register.xhtml-我的復合組件
<?xml version="1.0" encoding="UTF-8"?>
<!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"

<composite:interface>
<composite:attribute name="nameLable" />
<composite:attribute name="nameValue" />
<composite:attribute name="emailLable" />
<composite:attribute name="emailValue" />
<composite:attribute name="registerButtonText" />
<composite:attribute name="registerButtonAction"
method-signature="java.lang.String action()" />
</composite:interface>
<composite:implementation>
<h:form>
<h:message for="textPanel" style="color:red;" />
<h:panelGrid columns="2" id="textPanel">
#{cc.attrs.nameLable} :
<h:inputText id="name" value="#{cc.attrs.nameValue}" />
#{cc.attrs.emailLable} :
<h:inputText id="email" value="#{cc.attrs.emailValue}" />
</h:panelGrid>
<h:commandButton action="#{cc.attrs.registerButtonAction}"
value="#{cc.attrs.registerButtonText}"
/>
</h:form>
</composite:implementation>
</html>
和index.xhtml ,我嘗試在其中使用組件:
<?xml version="1.0" encoding="UTF-8"?>
<!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:h="http://java.sun.com/jsf/html"
xmlns:my_composite_component="http://java.sun.com/jsf/composite/my_composite_component"
>
<h:body>
<h1>Composite Components in JSF 2.0</h1>
<my_composite_component:register
nameLable="Name"
nameValue="#{user.name}"
emailLable="E-mail"
emailValue="#{user.email}"
registerButtonText="Register"
registerButtonAction="#{user.registerAction}"
/>
</h:body>
</html>
我使用的是jsf 2.2,而不是java.sun.com/jsf,我將其用作命名空間:
xmlns:my_composite_component="http://xmlns.jcp.org/jsf/composite/my_composite_component
