JAR问题中的复合组件与cc.attrs

时间：2011-11-29 21:46:32

标签： netbeans maven jsf-2 jar composite-component

对于我在JAR中打包的复合组件，我使用了<cc:interface>一个简单的<cc:attribute>，当然还有一个<cc:implementation>。

在开发阶段，我有一个javax.faces.view.facelets.TagException抱怨cc：interface组件未检测到标识符«j_idt6.getParent（）»。在生产阶段，它似乎有效，但<cc:attribute>的值没有按预期显示。

我在网上看到过JIRA问题JAVASERVERFACES-1903，但似乎有点旧。有没有人知道如何解决它？你认为这个问题有一天会得到解决吗？您如何使用项目处理JAR文件中的复合组件？

我的配置是Glassfish 3.1下的Mojarra 2.1.4。

从OP帖子更新，如下：

这是错误：

/file:/D:/Users/simplicity2k/Documents/NetBeansProjects/tmp/application/application-ear/target/gfdeploy/org.simplicity2k_application-ear_ear_1.0-SNAPSHOT/application-web-1.0-SNAPSHOT_war/WEB-INF/lib/components-1.0-SNAPSHOT.jar!/META-INF/resources/components/sampleOutput.xhtml @8,23 <cc:interface> Composant non détecté pour l’identificateur «j_idt6.getParent()».

堆栈跟踪：

    <cc:interface>
        <cc:attribute name="colorRed" default="F00" />
    </cc:interface>

    <!-- IMPLEMENTATION -->
    <cc:implementation>
        <h:panelGroup layout="block" styleClass="componentContainer" style="border:1px solid \##{cc.attrs.colorRed};">

您根本不需要taglib.xml文件。删除它并通过以下命名空间引用视图中的复合：

xmlns:ec="http://java.sun.com/jsf/composite/components"

“/ components”部分指的是资源文件夹中的文件夹“/ components”。

好的解决了。错误在名称空间中，并使用cc：xxx而不是composite：xxx 

    <?xml version="1.0"?>
    <facelet-taglib xmlns="http://java.sun.com/xml/ns/javaee"
                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xmlns:composite="http://java.sun.com/jsf/composite"
                  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facelettaglibrary_2_0.xsd"
                  version="2.0">

        <namespace>http://java.sun.com/jsf/composite</namespace>

        <tag>
            <tag-name>sampleExternalComponent</tag-name>
            <source>resources/ec/sampleExternalComponent.xhtml</source>
        </tag>

    </facelet-taglib>

组件：

<?xml version='1.0' encoding='UTF-8' ?>
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:composite="http://java.sun.com/jsf/composite"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:ui="http://java.sun.com/jsf/facelets">

    <ui:composition>
        <!-- INTERFACE -->
        <composite:interface>
            <composite:attribute name="color" default="000000" required="false" />
        </composite:interface>

        <!-- IMPLEMENTATION -->
        <composite:implementation>
            <h:outputText value="#{sampleExternalComponentBean} || #{sampleExternalComponentBean.name} || #{cc.id} || #{cc.attrs.color}" style="color: \##{cc.attrs.color};" />
        </composite:implementation>
    </ui:composition>
</html>

并在WAR中调用它：xmlns:ec="http://java.sun.com/jsf/composite/ec"和<ec:sampleExternalComponent id="ext" color="00F" />
