Jboss rich:fileUpload限制文件大小：maxRequestSize不起作用

我正在使用JBoss EPP 5.2.0和JSF 1.214、RichFaces 3.3.2.SR1以及org.JBoss.portletbridge 2.0.0.FINAL

我想重新设置上传文件的文件大小。 我尝试过以下方法：

xhtml：

<rich:fileUpload    id="uploader"
                    fileUploadListener="#{controller.fileUploadlistener}" 
                    immediateUpload="true" 
                    allowFlash="false"
                    maxFilesQuantity="#{controller.uploadsLeft}" 
                    acceptedTypes="pdf,jpg,tif,pgm,pbm,png">
            <a4j:support event="onuploadcomplete" reRender="uploadedFiles" /> 
</rich:fileUpload>

portlet.xml：

<filter>
    <filter-name>MyResourceFilter</filter-name>
    <filter-class>my.package.MyResourceFilter</filter-class>
    <lifecycle>RESOURCE_PHASE</lifecycle>
    <init-param>
        <name>maxRequestSize</name>
        <value>2000000</value>
    </init-param>
</filter>    

如果有人能检查一下代码就好了。 这对你合适吗

问候
