错误：“rich:modalPanel”的标记处理程序类在 Java 构建路径上找不到 (org.richfaces.taglib.ModalPanelTag)
我正在尝试 richface 4。似乎标签类没有在 JAVA 构建路径上设置。对于所有丰富的组件，我都收到此错误：“错误：在 Java 构建路径上找不到 * (org.richfaces.taglib.*) 的标记处理程序类”
对于 a4j 组件也是如此，对于所有组件，我都收到相同的错误“在 Java 构建路径上找不到“a4j:”(org.ajax4jsf.taglib.html.jsp.) 的标记处理程序类”
对于 richface4，我执行了以下操作：
1) 添加以下 jars：
annotations-4.0.0.Final.jar
cssparser-0.9.5.jar
guava-r08-gwt.jar
guava-r08.jar
jsf-api.jar
jsf-impl.jar
richfaces-components-api-4.1.0.Final.jar
richfaces-components-ui-4.1.0.Final.jar
richfaces-core-api-4.1.0.Final.jar
richfaces-core-impl-4.1.0.Final.jar
sac-1.3.jar
commons-beanutils-1.8.3.jar
commons-collections-3.2.1.jar
commons-digester-2.1-sources.jar
commons-digester-2.1.jar
commons-discovery-0.4.jar
jhighlight-1.0.jar
jsf-facelets-1.1.14.jar
默认生成 web.xml，并且不添加新元素。因为 RF4 中不需要更改（RF3.3 中需要更改）。
JSP 文件是
<?xml version="1.0" encoding="ISO-8859-1" ?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:a4j="http://richfaces.org/a4j" xmlns:rich="http://richfaces.org/rich" version="2.0">
<jsp:directive.page language="java"

</head>
<body>
<f:view>
<h:form>
<a4j:commandLink
value="Opss! I forgot password"
reRender="forgetPasswordPanel"
oncomplete="#{rich:component('forgetPasswordPanel')}.show()">
</a4j:commandLink>
</h:form>
<rich:modalPanel id="forgetPasswordPanel" autosized="true" width="380">
<f:facet name="header">
<h:outputText value="Reset Password"/>
</f:facet>
</rich:modalPanel>
</f:view>
</body>
</html>
</jsp:root>
我进一步调查这个问题，发现 taglib(tld 文件) 不包含许多 rich 和 a4j 组件的标记类，并且 richFace4.1 jar 没有相应的 java 类（位于 richFaces 3.3 jar 中） 。
我缺少一些罐子吗？与 richface4 合作我还应该做什么？
I am trying richface 4. It seems tags class are not setting on JAVA build path. I am getting this error for all rich component: "ERROR: tag handler class for * (org.richfaces.taglib.*) was not found on the Java Build Path"
For a4j component also, for all component i am getting same error "The tag handler class for "a4j:" (org.ajax4jsf.taglib.html.jsp.) was not found on the Java Build Path"
For richface4, i performed following actoin:
1) Added following jars:
annotations-4.0.0.Final.jar
cssparser-0.9.5.jar
guava-r08-gwt.jar
guava-r08.jar
jsf-api.jar
jsf-impl.jar
richfaces-components-api-4.1.0.Final.jar
richfaces-components-ui-4.1.0.Final.jar
richfaces-core-api-4.1.0.Final.jar
richfaces-core-impl-4.1.0.Final.jar
sac-1.3.jar
commons-beanutils-1.8.3.jar
commons-collections-3.2.1.jar
commons-digester-2.1-sources.jar
commons-digester-2.1.jar
commons-discovery-0.4.jar
jhighlight-1.0.jar
jsf-facelets-1.1.14.jar
web.xml is default generated and NO new element is added. As it is not required to change in RF4 (which is required in RF3.3).
JSP file is
<?xml version="1.0" encoding="ISO-8859-1" ?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:a4j="http://richfaces.org/a4j" xmlns:rich="http://richfaces.org/rich" version="2.0">
<jsp:directive.page language="java"
contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1" />
<jsp:text>
<![CDATA[ <?xml version="1.0" encoding="ISO-8859-1" ?> ]]>
</jsp:text>
<jsp:text>

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>TESTING</title>
</head>
<body>
<f:view>
<h:form>
<a4j:commandLink
value="Opss! I forgot password"
reRender="forgetPasswordPanel"
oncomplete="#{rich:component('forgetPasswordPanel')}.show()">
</a4j:commandLink>
</h:form>
<rich:modalPanel id="forgetPasswordPanel" autosized="true" width="380">
<f:facet name="header">
<h:outputText value="Reset Password"/>
</f:facet>
</rich:modalPanel>
</f:view>
</body>
</html>
</jsp:root>
i further investigated this issue and found that taglib(tld file) doesn't contain tag-class for many rich and a4j component and richFace4.1 jar does not have corrosponding java class for them (which is in richFaces 3.3 jars).
Am i missing some jars ? What else should i do to work with richface4 ?

您似乎正在尝试将 RichFaces 3.3 Web 应用程序升级到 RichFaces 4.1。您需要做的更改不仅仅是替换 JAR 文件。您可以在他们自己的文档中找到确切的迁移步骤：RichFaces 3.3.x 到 4.x 迁移指南。
例如，JSP 已被弃用并被 Facelets 取代，您需要将 JSP 重写为 XHTML。
reRender属性已替换为update属性。等等。另外，Facelets 1.x 的jsf-facelets-1.1.14.jar应该从/WEB-INF/lib中删除。 JSF 2.x 库已经捆绑了正确的 Facelets 2.x 实现。另请参阅：
You seem to be trying to upgrade a RichFaces 3.3 web application to RichFaces 4.1. You need to do many more changes than only replacing the JAR files. You can find the exact migration steps in their own documentation: RichFaces 3.3.x to 4.x migration guide.
For example, JSP is been deprecated and replaced by Facelets, you'd need to rewrite your JSPs to be XHTMLs. The
<rich:modalPanel>is been replaced by<rich:popupPanel>, you need to find and replace all those tags accordingly. ThereRenderattribute is been replaced byupdateattribute. Etcetera. Also thatjsf-facelets-1.1.14.jarwhich is of Facelets 1.x should be removed from the/WEB-INF/lib. JSF 2.x libraries already ships with the right Facelets 2.x implementation bundled.See also:
