how can I add parameters in FileUpload

[zujee]

Hi,
How can i add parameter in FileUpload in the formPanel. I successfully
uploaded the file to server. But I want to pass some string values
along with the uploadForm.submit(); .

How can I do that.
Thanks in advance

What i do is i add hidden inputs to the form i'm submitting along with
my picture, like so....

private Hidden formTime = new Hidden();
private HorizontalPanel formHP=new HorizontalPanel();
public FormPanel uploadForm=new FormPanel();//form

formTime.setName("time");
formTime.setValue(""+picTime);
formHP.add(formTime);
uploadForm.add(formHP);

then on the server.....something along these lines.....

public synchronized void doPost(HttpServletRequest request,
HttpServletResponse res)throws ServletException, IOException{
res.setContentType("text/html;charset=utf-8");

item=null;

//System.err.println("selectMstsq: "+selectMstsq);
if(myWeb==null)myWeb=new PictureUploadServer();

File tempFolder =
(File)request.getSession().getServletContext().getAttribute("com.google.gwt.dev.shell.outdir");

//Check that we have a file upload request
boolean isMultipart = ServletFileUpload.isMultipartContent(request);

// Create a factory for disk-based file items
FileItemFactory factory = new DiskFileItemFactory();

// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);

// Parse the request
items = new LinkedList();

try {
items = upload.parseRequest(request);

} catch (FileUploadException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

iter = items.iterator();

while (iter.hasNext()) {
item = (FileItem) iter.next();
String name = item.getFieldName();
if(name.compareTo("time") == 0){
picTime=Long.parseLong(item.getString());
}else if(name.startsWith("picture")){
uploadedStream = item.getInputStream();
/* This is to dump the upload to disk (create file)
* To keep in memory, change the output stream to
* ByteArrayOutputStream, writing file contents
* into a byte array.
* This byte array can be used as input to a ByteInputSream
* which in turn can be written to javax.sql.InputStream
*/
}
}
}

Hope that spoon feeding has filled you up, :).
