    Are you looking to do this in a Java(Servlet) or Javascript?

    There is a massive difference between each.

    Might I suggest Google?
    There's rather a lot of stuff out there for file uploading in servlets.

    I have following code but it's not working :
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html>
    <%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
    <%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
    <%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>

    <head>
    <script type="text/javascript">

    </script>
    </head>
    <body>
    <!-- upload.jsp -->

    <%@ page import="java.io.*" %>
    <%
    //to get the content type information from JSP Request Header

    String contentType = request.getContentType();

    //here we are checking the content type is not equal to Null and
    //as well as the passed data from mulitpart
    //form - data
    // is greater than or
    //equal to 0
    if ((contentType != null) && (contentType.indexOf("multipart/form - data") >= 0)) {

    DataInputStream in = new DataInputStream(request.getInputStream());
    //we are taking the length of Content type data
    int formDataLength = request.getContentLength();
    byte dataBytes[] = new byte[formDataLength];
    int byteRead = 0;
    int totalBytesRead = 0;
    //this loop converting the uploaded file into byte code
    while (totalBytesRead < formDataLength) {
    byteRead = in.read(dataBytes, totalBytesRead,
    formDataLength);
    totalBytesRead += byteRead;
    }
    String file = new String(dataBytes);
    //for saving the file name
    String saveFile = file.substring(file.indexOf("filename=\"") + 10);
    saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
    saveFile = saveFile.substring(saveFile.lastIndexOf("\\")
    + 1, saveFile.indexOf("\""));
    int lastIndex = contentType.lastIndexOf("=");
    String boundary = contentType.substring(lastIndex + 1,
    contentType.length());
    int pos;
    //extracting the index of file
    pos = file.indexOf("filename=\"");
    pos = file.indexOf("\n", pos) + 1;
    pos = file.indexOf("\n", pos) + 1;
    pos = file.indexOf("\n", pos) + 1;
    int boundaryLocation = file.indexOf(boundary, pos) - 4;
    int startPos = ((file.substring(0, pos)).getBytes()).length;
    int endPos = ((file.substring(0, boundaryLocation)).getBytes()).length;

    // creating a new file with the same name and writing the content in =new fileFileOutputStream

    OutputStream fileOut = new FileOutputStream("E:/"+saveFile);
    fileOut.write(dataBytes, startPos, (endPos - startPos));
    fileOut.flush();
    fileOut.close();
    %><Br>
    <table border="2">
    <tr>
    <td>
    <b>You have successfully
    upload the file by the name of:</b>
    <% out.println(saveFile);%>
    </td>
    </tr>
    </table> <%}%>


    </body>

    That's not a servlet...it's a JSP.
    You shold only have display code in a JSP.
    Debugging that to find out what's wrong with it is a lot harder as a JSP.

    But I will ask why you are turning a perfectly useable InputStream and turning it into a DataInputStream?

    Why didn't you simply go with the Apache stuff which is the first link?
    And it has code and everything...

    1. This is a rather old thread.
    2. That's not uploading an image, that's displaying an image.
