我正在尝试让FileUpload功能使用Icefaces ace:fileEntry，但未调用服务器上的fileUploadListener，这里是代码：

        <h:commandButton value="Upload File"/>

java piece 

public void uploadFile(FileEntryEvent event)
    {
        FileEntry fileEntry = (FileEntry) event.getSource();
        FileEntryResults results = fileEntry.getResults();
        for (FileEntryResults.FileInfo fileInfo : results.getFiles())
        {
            if (fileInfo.isSaved())
            {
                log.debug("########### FILE IS SAVED ########");
            }
        }
    }

现在，在当前状态下，我可以打开文件系统导航弹出窗口，我可以选择文件但是fileUploadListener应该被点击但是现在它没有，我也能够得到一些我设置的数据在服务器端，所以服务器旅行只有问题我有fileUploadListener未命中，有任何建议吗？

更新 我仍然在寻找答案，因为我无法将文件成功上传到服务器。

更新2 现在我得到Content is not allowed in prolog异常，不确定究竟是什么意思，这里是stacktrace：

    ERROR [Faces Servlet]  - Servlet.service() for servlet Faces Servlet threw exception: javax.faces.view.facelets.Facele

我的组件周围没有<h:form>，代码中是否有任何内容？ 我对icefaces没有任何经验，但我正在使用richFaces。 用

<rich:fileUpload immediate="true" id="fileUploadId" 
                        ajaxSingle="true" listHeight="70px" listWidth="500px"
                        uploadButtonClass="otherButton" styleClass="backgroundColorInput"
                        addButtonClass="otherButton"
                        fileUploadListener="#{paramActions.fileUploadListener}">
                        <a:support event="onuploadcomplete" reRender="paramsForm" />
                    </rich:fileUpload>

需要将其括在

中 
<h:form id="paramsForm" enctype="multipart/form-data">
fileUpload需要

multipart / form-data enctype

大多数时候未关闭的标签会导致该异常。检查xhtml，你可能会找到任何打开的标签。

例如：任何开放的div或span ..

答案 2 :(得分：0)

从enctype="multipart/form-data"移除h:form，如果没有它，它应该可以正常工作。

答案 3 :(得分：0)

我在JBoss 7.1服务器上遇到了这个问题。我有一个EAR项目，一些EJB项目和几个WAR项目。当我遇到问题时，我在EAR库中部署了icefaces jar，但当我将它们移动到使用ace：fileentry的WAR项目时，它开始工作。
