    Default Display file name

    Hi,

    I have a form linked to a servlet that uploads files. I would like the name of the file that has been uploaded to be displayed next to the <h3>line once it has been processed. I have no problems linking the servlet to the form or uploading the file. I simply want the name of the uploaded file to appear next to the word uploaded. Thank you for your help in advance.


    // Generate some sample HTML
    response.setContentType("text/html");
    PrintWriter out = response.getWriter();
    out.println("<html><head><title>Fileupload</title></head>");
    out.println("<body>");
    out.println("<h3>Your file has been successfully uploaded</h3>");
    out.println("<h3>The following file was uploaded </h3>"); // Name of file should appear next to the word uploaded.
    out.println("</body>");
    out.println("</html>");
    }

    Hi,

    I'm using external library from
    Apache Commons FileUpload API
    to work with upload.

    Here is part of code for upload servlet to help you:

    ...
    Java Code: 
    protected void [B]doPost[/B](HttpServletRequest request, HttpServletResponse response) 
		throws ServletException, IOException {

    String message = "";

		// have file upload request been sent 
		if (!ServletFileUpload.isMultipartContent(request)) {
			message = "File not sent!";
			System.out.println(message);
			showError(request, response, message);
			return;
		}
		
		// if it is MultipartContent that is file 

		// Parsing the form data with the Apache Jakarta Commons FileUpload library:

		try {
   ServletFileUpload servletFileUpload = new ServletFileUpload(
		new DiskFileItemFactory()
);

	List fileItemsList = servletFileUpload.parseRequest(request);

// no need to iterate, there is only 1 member of list and it is file
FileItem fileItem = (FileItem) fileItemsList.get(0);

// true if the instance represents a simple form field; false if it represents an uploaded file
			if (fileItem.isFormField()) {
			    message = " It's not file! ";
				System.out.println(message);
				showError(request, response, message);
				return;
			}

	// The file item contains an uploaded file
	System.out.println("The file item contains an uploaded file");
	
[B]System.out.println("file name : " + fileItem.getName());
[/B]System.out.println("file size: " + fileItem.getSize());
...
    cheers!
