I have no clue about JSP but in PHP that's no problem: Download: zip the file dynamically and give the user the link. View: either just give the user a link to the file or, a much better solution, read the file with PHP and output it with some css formatting. I don't know if you have the possibility to use PHP, I hope this helps.

The easy option would be just to supply a link to the file. Assuming it's just a text file, when the user clicks on the link, the browser should render the file contents on screen or pop up the download window.

If you want to display the file contents within your JSP page (a textarea for example) you'll need to do something server side with your JSP/Servlet code.

Somthing like this should do it:

Code: Select all

public static String getStringFromFile(String path)
    throws IOException {
        StringBuffer buff = new StringBuffer(5000);
        BufferedReader in = new BufferedReader(new FileReader(path));
        try {
            String line = null;
            while ((line = in.readLine()) != null) {
                buff.append(line).append('\n');
            }
        } catch (IOException ex) {
            log.error("Problem getting string from file", ex);
            throw ex;
        } finally {
            if (in != null) in.close();
        }
        return buff.toString();
    }

This method returns the contents of a file as a string that you can then display in your JSP page.

Hope this helps.
