org.apache.jasper.JasperException: /JSP/BillingPayment.jsp(15,3) 没有标签“ajax”在以前缀“f”导入的标签库中定义

对 JSF 2 有一些疑问，我只想使用 JSF 2 的 ajax 功能，而不打算使用它的任何实现。

已从 http 获取 JSF 库： //download.java.net/maven/2/com/sun/faces/jsf-api/2.1.1-b03/

但这些仍然不支持我用来实现功能的ajax标签。

我收到错误 org.apache.jasper.JasperException: /JSP/BillingPayment.jsp(15,3) 在以前缀“f”导入的标签库中没有定义标签“ajax” 对于以下请求。

<%@ taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@ taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<html>
<body>
<h:form>
    <h:panelGrid>
        <h:inputText value="#{dataTableBean.sponsorID}">
            <f:ajax event="keyup" />
        </h:inputText>
        <h:outputText id="text" value="#{dataTableBean.sponsorID}" />
    </h:panelGrid>
</h:form>
</body>
</html>

为此，我认为我没有合适的库，请给我支持 ajax 的正确 JSF2 库。

Have some doubt with JSF 2, I would like to use the ajax functionality of JSF 2 only, not going to use any of its implementations.

Have taken the JSF libraries from http://download.java.net/maven/2/com/sun/faces/jsf-api/2.1.1-b03/

But still none of these are supporting the ajax tag that I am using to implement the functionality.

I get the error
org.apache.jasper.JasperException: /JSP/BillingPayment.jsp(15,3) No tag "ajax" defined in tag library imported with prefix "f"
for the following request.

<%@ taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@ taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<html>
<body>
<h:form>
    <h:panelGrid>
        <h:inputText value="#{dataTableBean.sponsorID}">
            <f:ajax event="keyup" />
        </h:inputText>
        <h:outputText id="text" value="#{dataTableBean.sponsorID}" />
    </h:panelGrid>
</h:form>
</body>
</html>

For this I presume, I am not having the proper library, please can you give me the correct JSF2 library that supports ajax.

您必须使用 Facelets 技术。您的 sth.xhtml 将具有此形式

<?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:f="http://java.sun.com/jsf/core">
<h:head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"></meta>
    <link rel="stylesheet" type="text/css" href="my.css" />
</h:head>
<h:body>
</h:body>
</html>

如果您在创建 jsf 页面时使用 netbeans ide 7.1，则，请检查 faceletes 选项。
我有一个类似的问题
h:outputScript 未在库 h 中定义。

You have to use Facelets Technology. Your sth.xhtml will have this form

<?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:f="http://java.sun.com/jsf/core">
<h:head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"></meta>
    <link rel="stylesheet" type="text/css" href="my.css" />
</h:head>
<h:body>
</h:body>
</html>

If you are using netbeans ide 7.1 when you are creating a jsf page check the faceletes option.
I had a similar question
h:outputScript not defined in library h.

您的链接指向 jsf-api.jar。您还需要 jsf-impl.jar，您可以在此目录。

如果您的类路径中包含这两者，您应该能够访问 TLD。我认为没有 jsf-impl.jar 就无法使用 jsf。

此外，您必须使用 f:view 标记在页面上包含所有组件标记。所以你的页面应该具有以下结构：

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<f:view>
 <html>
  <body>
    <h:form>
      <h:panelGrid>
        <h:inputText value="#{dataTableBean.sponsorID}">
          <f:ajax event="keyup" />
        </h:inputText>
        <h:outputText id="text" value="#{dataTableBean.sponsorID}" />
      </h:panelGrid>
   </h:form>
  </body>
 </html>
</f:view>

Your link points to the jsf-api.jar. You need jsf-impl.jar as well which you can find in this directory.

If you have both in your classpath, you should be able to access the TLDs. I think there's no way to use jsf without a jsf-impl.jar.

Furthermore, you have to include all components tags on your page with the f:view tag. So your page should have the following structure:

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<f:view>
 <html>
  <body>
    <h:form>
      <h:panelGrid>
        <h:inputText value="#{dataTableBean.sponsorID}">
          <f:ajax event="keyup" />
        </h:inputText>
        <h:outputText id="text" value="#{dataTableBean.sponsorID}" />
      </h:panelGrid>
   </h:form>
  </body>
 </html>
</f:view>
