Please please please help me, I am stuck on this for quiet a while and checked the previous posts here, but still could not fix this. My code is as below, when run it, it always shows failure, and nothing uploaded on the server.
1) I don't know which line to set up the folder on the server for me to save the images, it is: "/upload/"
2) I searched the online posts, says I need to install the "The Commons FileUpload package" through
http://commons.apache.org/fileupload/index.html, I don't know how to install the page, in which folder of my server?
Really appreciate your help.

index.jsp:
<form method="post" ACTION="upload.jsp" name="uploadForm" ENCTYPE='multipart/form-data'>
<input type="file" name="uploadFile" >
<input type="submit" name="Submit" value="Submit">
<input type="reset" name="Reset" value="Reset">
</form>

My "upload.jsp" is as:

String contentType = request.getContentType();
System.out.println("Content type is :: " + contentType);

{
DataInputStream in = new DataInputStream(request.getInputStream());
int formDataLength = request.getContentLength();
dataBytes = new byte[formDataLength];
int byteRead = 0;
int totalBytesRead = 0;
while (totalBytesRead < formDataLength)
{
byteRead = in.read(dataBytes, totalBytesRead, formDataLength);
totalBytesRead += byteRead;
}
String file = new String(dataBytes);
saveFile = file.substring(file.indexOf("filename=\"") + 10);
saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
saveFile = saveFile.substring(saveFile.lastIndexOf("\\") + 1, saveFile.indexOf("\""));
// out.print(dataBytes);
int lastIndex = contentType.lastIndexOf("=");
String boundary = contentType.substring(lastIndex + 1, contentType.length());
// out.println(boundary);
int pos;
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;
try
{
FileOutputStream fileOut = new FileOutputStream("c://"+saveFile);
// fileOut.write(dataBytes);
fileOut.write(dataBytes, startPos, (endPos - startPos));
fileOut.flush();
fileOut.close();
imageSave="Success";
}catch (Exception e)
{
System.err.println ("Error writing to file");
imageSave="Failure";
}
