hi,
i use Hidden in client-side
Hidden hidden = new Hidden(name, value);
server-side in do-post:
DiskFileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
response.setCharacterEncoding("UTF-8");
List items = null;
try
{
items = upload.parseRequest(request);
}
catch (FileUploadException e)
{
LOG.warn(".", e);
}
// if(items!=null..)
for(FileItem item : items)
{
// add code, what you want can like this coming
code
// item.getName() item.getString()
item.getString("UTF-8") item.getFieldName()
}
maybe help you!
