Faces Servlet - ClassNotFound異常

我正在開發一個使用JSF 1.2和PrimeFaces 3.5的示例應用程序。我在桌面上安裝了RAD，並創建了一個新的動態Web項目。我已經用primeface編輯器標籤編寫了xhtml文件。但是，當我運行該項目時，它會爲FacesServlet拋出「java.lang.ClassNotFoundException」，儘管servlet存在於類路徑中。Faces Servlet - ClassNotFound異常

我的web.xml文件看起來像這樣

<?xml version="1.0" encoding="UTF-8"?> 
<web-app id="WebApp_ID" version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> 
    <display-name> 
    PrimeFacesNew</display-name> 
    <context-param> 
     <param-name>javax.faces.PROJECT_STAGE</param-name> 
     <param-value>Development</param-value> 
    </context-param> 
    <!-- JSF mapping --> 
    <servlet> 
     <servlet-name>Faces Servlet</servlet-name> 
     <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 
    <!-- Map these files with JSF --> 
    <servlet-mapping> 
    <servlet-name>Faces Servlet</servlet-name> 
     <url-pattern>*.xhtml</url-pattern> 
    </servlet-mapping> 
    <welcome-file-list> 
     <welcome-file>HelloWorld.xhtml</welcome-file> 
    </welcome-file-list> 
</web-app>

和我HelloWorld.xhtml看起來像這樣

<html xmlns="http://www.w3.org/1999/xhtml" 
    xmlns:h="http://java.sun.com/jsf/html" 
    xmlns:f="http://java.sun.com/jsf/core" 
    xmlns:ui="http://java.sun.com/jsf/facelets" 
    xmlns:p="http://primefaces.org/ui"> 
<h:head> 
</h:head> 
<h:body> 
    <h1>Hello World PrimeFaces</h1> 

    <h:form> 
     <p:editor value="This is PrimeFace editor" /> 
    </h:form> 

</h:body> 
</html>

我已經在我的classpath中添加以下jar文件..

myfaces- api-2.1.12.jar
myfaces-impl-2.1.12.jar
myfaces-bundle-2.1.12.jar
SLF4J-API-1.7.5.jar
SLF4J-簡單1.7.5.jar
primefaces-3.5.jar

，當我跑了使用RAD的Tomcat 6.0，它是引發異常下面..

素面元件也顯示爲RAD中的問號。我在谷歌嘗試了所有可能的解決方案，但它並沒有爲我工作。請糾正我在哪裏做錯了..

謝謝。

PrimeFaces 3.5無法在JSF 1.2下運行，您需要JSF 2.X. –

哦，我不知道這一點。讓我嘗試添加2.0罐並嘗試。 – samuelebe

Alex：我使用myfaces-2.1.2.jar，FacesServlet來自該jar。所以，我想我正在使用JSF 2.1 jar。 – samuelebe
