Myfaces2和Tomahawk2扩展过滤器



我已经在一个问题上挣扎了好几天了,我不知道该怎么做才能让它工作。我尝试使用与javascript一起工作的Tomahawk组件…我总是得到一个javascript错误:"xxx是未定义的" (xxx=orgApacheMyfacesPopup为例)。

据我所知,这似乎是一个扩展过滤器问题:服务器无法提供包含所需定义的.js…但是我看不出有什么问题。

我刚刚用eclipse从头开始做了一个小项目,我总是得到错误。

我遵循的步骤是:

  1. 创建一个新的Web应用程序项目(目标是Tomcat 6,增加对JSF2.0下载Myfaces2的支持)
  2. 下载并复制jsstl-api-1.2.jar和jstl-impl-1.2.jar到WEB-INF/lib
  3. 下载Tomahawk for JSF2并复制jar到WEB-INF/lib
  4. 修改web.xml(交付后)
  5. 创建index.xhtml(交付后)

My web.xml:

My index.xhtml文件:

        xmlns:c="http://java.sun.com/jsp/jstl/core"
        >
    <body>
        <h:form>
            <t:popup    styleClass="popup"
                    closePopupOnExitingElement="false"
                        closePopupOnExitingPopup="false"
                        displayAtDistanceX="0"
                        displayAtDistanceY="0"
                        >
                <h:outputText value="test popup" />
                <f:facet name="popup">
                    <h:panelGroup>
                        <h:outputText     value="foo"/>
                    </h:panelGroup>
                </f:facet>
            </t:popup>
        </h:form>
    </body>
</html>

有人明白为什么它不起作用吗?

PS:我用Tomecat 7试过了,但效果并不好…

感谢

没有?有人让Myfaces2和tomahawk2与javascript和xhtml一起工作吗?有人知道在哪里可以找到样品吗?MyFaces网站上的示例似乎针对JSF 1.1和类似jsp的页面…

您需要一个<h:head>而不是<head>,以便自动包含特定于JSF组件的JavaScript(和CSS)文件。另外,最好也用<h:body>代替<body>

正确的Facelet模板应该是这样的:

<!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:t="http://myfaces.apache.org/tomahawk">
    <h:head>
        <title>Title</title>
    </h:head>
    <h:body>
        <h1>Body</h1>
    </h:body>
</html>
