我想得到FileUpload与 Icefaces 配合使用的功能ace:文件条目 but my fileUploadListener服务器上未调用，代码如下：
xhtml 片段：

</h:form>
</h:body>
</html>

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，并且可以选择文件，但是然后fileUploadListener应该被击中，但现在没有，我也能够获取我在服务器端设置的一些数据，因此服务器行程正在工作，我遇到的唯一问题是fileUploadListener还没打，有什么建议吗？
Update我仍在寻找答案，因为我无法成功地将文件上传到服务器。
Update 2现在正在得到Content is not allowed in prolog异常，不确定这到底意味着什么，这是堆栈跟踪：
ERROR [Faces Servlet] - Servlet.service() for servlet Faces Servlet threw exception: javax.faces.view.facelets.Facele
tException: Error Parsing /trade_entry/UploadBlotter.xhtml: Error Traced[line: 2] Content is not allowed in prolog.
