Question

我的Java EE网络应用正在与玻璃鱼2.1做精细工作。现在我想向玻璃鱼3.1.1迁移,但在成功部署战争档案之后,它造成以下错误:

WARNING: ApplicationDispatcher[/Myapp] PWC1231: Servlet.service() for servlet Faces Servlet threw exception
java.lang.IllegalStateException: Illegal attempt to set ViewHandler after a response has been rendered.

My application uses following frameworks.

Spring Framework 3.0.2
JSF 2.0
RichFaces 3.3.3 Final

该表与JDK1.6合编。

这一问题是如何造成的,我如何解决这一问题?

我遵循了所提供的修改:。

丰富多彩的我的属性如下:

   <dependency>
        <groupId>org.richfaces.framework</groupId>
        <artifactId>richfaces-api</artifactId>
        <version>3.3.3.Final</version>
    </dependency>
    <dependency>
        <groupId>org.richfaces.framework</groupId>
        <artifactId>richfaces-impl-jsf2</artifactId>
        <version>3.3.3.Final</version>
    </dependency>
    <dependency>
        <groupId>org.richfaces.ui</groupId>
        <artifactId>richfaces-ui</artifactId>
        <version>3.3.3.Final</version>
    </dependency>

我的脆弱之处在于:

        <dependency>
            <groupId>com.sun.faces</groupId> 
            <artifactId>jsf-api</artifactId> 
            <version>2.0.2</version> 
        </dependency>
        <dependency>
            <groupId>com.sun.faces</groupId> 
            <artifactId>jsf-impl</artifactId> 
            <version>2.0.2</version> 
        </dependency>

添加以下内容:

<context-param>
    <param-name>org.ajax4jsf.VIEW_HANDLERS</param-name>
    <param-value>com.sun.facelets.FaceletViewHandler</param-value>
</context-param>
<context-param>
    <param-name>javax.faces.DISABLE_FACELET_JSF_VIEWHANDLER</param-name>
    <param-value>true</param-value>
</context-param>

修改了我的申请说明,修改了2.5版。

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/j2ee" 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">

我在座席上的发言如下:

 <application>
        <navigation-handler >
            org.navigation.CustomNavigationHandler
        </navigation-handler>

        <view-handler>
            org.ajax4jsf.application.AjaxViewHandler
        </view-handler>
<!--        <view-handler>
            com.sun.facelets.FaceletViewHandler
        </view-handler>-->
        <variable-resolver>org.springframework.web.jsf.DelegatingVariableResolver</variable-resolver>
        <message-bundle>MyMessages</message-bundle>
    </application>

Application get deployed successfully but after that i am getting error of class cast exception at the time starting an application in browser :

服务器记录如下:

INFO: myApp was successfully deployed in 21,635 milliseconds.
SEVERE: Error Rendering View[/login.xhtml]
javax.faces.FacesException: java.lang.ClassCastException: java.lang.String cannot be cast to javax.faces.component.UIComponent
    at com.sun.faces.application.ApplicationImpl.createComponentApplyAnnotations(ApplicationImpl.java:1923)

如何解决这一问题?

Answer 1

java.lang.IllegalStateException:不合法地试图在答复后提出观点。

当你使用共同财产基金1.2的专用组成部分图书馆,介绍共同财产基金2.x环境时,这是一个典型的错误信息。 RichFaces 3.3.x是用于F 1.2的,但玻璃鱼3.1号船与F 2.1号船,而不是像玻璃鱼2.1号那样的JF1.2号船。在第二份共同提交书中,观点处理领域发生了许多变化,因为共同提交书已被折旧,由面纱取代。

RichFaces在第二个共同未来论坛环境中安装和配置RichFaces 3.3.3的极佳指南:RichFaces 3.3.3和JF2.0。解决这一特殊例外的关键步骤是增加以下可分解共同财产基金的背景参数。 2 面对面观点

<context-param>
     <param-name>javax.faces.DISABLE_FACELET_JSF_VIEWHANDLER</param-name>
     <param-value>true</param-value>
</context-param>

但还需要采取更多步骤。全面阅读指南。

Answer 2

我不得不将Ajax4jsf图书馆从我的申请中删除,然后才能消除这一错误。显而易见,Ajax4jsf图书馆与JF2.0不兼容。
