-----------说明
  我的页面上的写法是：
<f:fileupload folder="<%="/feapp/sasfile/"+request.getRemoteAddr() +"/"%>" auto="true" checkFile="true" fileDesc="上传模板文件仅限仅限SAS/XML/RAQ格式" fileExt="*.sas;*.xml;*.raq" queueSizeLimit="1000" buttonImg="../../resources/libs/ext/extention/uploadify/buttonImg.gif" width="210"></f:fileupload>
一个自定义标签，websphere 不支持  动态属性值
folder="<%="/feapp/sasfile/"+request.getRemoteAddr() +"/"%>" 我在jetty和tomcat都是没问题的。客户的应用服务器是webspere6.1 请问大家这个问题如何解决呢？
