jsp设置网页根目录

  <%       String path = request.getContextPath();       String basePath = request.getScheme()+"://" +request.getServerName()+":" +request.getServerPort()+path+"/" ;       //System.out.println("path="+path);    //System.out.println("basePath="+basePath);    %>       <base href="<%=basePath%>" > 

这样设置之后，路径就可以从根目录开始了：

<form id="submit_form" method="post" action="/search/upload_iframe"  </form>
