Question

我正在从JBoss 6升级到JBoss 8（WildFly）。 RichFaces 3.3.3的版本保持不变。代码中的几个地方调用RichText spacer，如下所示：

<rich:spacer height="15" width="5"/>

在web.xml中，与Faces相关的servlet-mapping条目如下所示：

<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>/faces/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.faces</url-pattern>
</servlet-mapping>

运行JBoss 6时，间隔图像有以下URL，工作正常：

https://host.com/dc/a4j/g/3_3_3.Finalimages/spacer.gif

当我们升级到JBoss 8时，我们开始遇到问题。这个URL突然看起来像这样，并在访问时返回404 Not Found：

https://host.com/dc/faces/a4j/g/3_3_3.Finalimages/spacer.gif

我尝试从*.jsf，like the documentation specifies删除servlet-mapping web.xml以外的所有内容。这使得URL看起来像这样：

https://host.com/dc/a4j/g/3_3_3.Finalimages/spacer.gif.jsf

访问时，URL返回500内部服务器错误：

ERROR [io.undertow.request] (default task-29) UT005023: Exception handling request to /dc/a4j/g/3_3_3.Finalimages/spacer.gif.jsf: javax.servlet.ServletException: org.ajax4jsf.resource.ResourceNotFoundException: Resource not registered : images/spacer.gif.jsf

图片始终可用原始网址。

我只是假设绕过这个问题并取消间隔，但是RichFaces也会在我们当前使用的一些组件内部调用spacer。

我该怎么做才能让间隔物正确显示？

您应该在web.xml的filter和filter-mapping部分中排除org.ajax4jsf.Filter的第二次初始化。 Seam从Ajax4jsfFilterInstantiator类中实例化org.ajax4jsf.Filter。

请从web.xml中删除以下代码

<filter>
    <display-name>RichFaces Filter</display-name>
    <filter-name>richfaces</filter-name>
    <filter-class>org.ajax4jsf.Filter</filter-class>
</filter>
... 

<filter-mapping>
    <filter-name>richfaces</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>INCLUDE</dispatcher>
</filter-mapping>
