[紧急求助]ZK5:Windows2008上传文件出错

各位世外高人:

本人有一zk5 程序,上传文件在WinXP/Win2003 没有任何问题，但在win2008上，老是出错.错误提示如下(上传文件实际只有500k):

contentID is required !

代码如下zul)

<zscript>
      <![CDATA[
      
        public void FileProcess(String Strtype) throws Exception
        {
          Desktop desktop = self.getDesktop();
          
          org.zkoss.zk.ui.util.Configuration conf = desktop.getWebApp().getConfiguration();
          
          conf.setMaxUploadSize(20480);                

          conf.setUploadCharset("UTF-8");
          
          Object media = Fileupload.get(1);                
          
          if (media != null)
          {                                                                            
            winTcexamitemdata.UploadTcFile(media,Strtype) ;                                                                            
          }
        }          
      ]]>
    </zscript>

<image src="/cgsimages/Doc.gif" id="btnUserAdditionalInfofile" >
          
              <attribute name="onClick">
                <![CDATA[
                    FileProcess("UserAdditionalInfofile");
                  ]]>
             </attribute>
              </image>

理论上应该视差不多的才对，会有差的话确认一下zk.xml 中
有没有特别针对 event thread 作特别的设定

zk.xml 内容,请帮忙检查,多谢
