I have tried using the code as below for file uploading.When run,it gives me an error as java.lang.IndexOutOfBoundsException,PLease help


The code is:

<!-- upload.jsp -->
<%@ page import="java.io.*" %>
<%
String contentType = request.getContentType();
System.out.println("Content type is :: " +contentType);
if ((contentType != null) && (contentType.indexOf("multipart/form-data") >= 0))
{
DataInputStream in = new DataInputStream(request.getInputStream());
int formDataLength = request.getContentLength();
byte 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);
String saveFile = file.substring(file.indexOf("filename=\"") + 10);
//out.print("FileName:" + saveFile.toString());
saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
//out.print("FileName:" + saveFile.toString());
saveFile = saveFile.substring(saveFile.lastIndexOf("\\") + 1,saveFile.indexOf("\""));
//out.print("FileName:" + saveFile.toString());
//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;
saveFile = "C:\\Program Files\\Apache Software Foundation\\Tomcat 5.5\\webapps\\ROOT\\Extrusions\\" + saveFile;
FileOutputStream fileOut = new FileOutputStream(saveFile);
//fileOut.write(dataBytes);
fileOut.write(dataBytes, startPos, (endPos - startPos));
fileOut.flush();
fileOut.close();
out.println("File saved as " +saveFile);
}

how to store the uploading file in data base (MS-Access), i tried this code but this is storing data in specified path only so please help me

this is code
<!-- upload.jsp -->
<%@ page import="java.io.*" %>
<%
String contentType = request.getContentType();
System.out.println("Content type is :: " +contentType);
if ((contentType != null) && (contentType.indexOf("multipart/form-data") >= 0)) {
DataInputStream in = new DataInputStream(request.getInputStream());
int formDataLength = request.getContentLength();

byte 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);
String saveFile = file.substring(file.indexOf("filename=\"") + 10);
//out.print("FileName:" + saveFile.toString());
saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
//out.print("FileName:" + saveFile.toString());
saveFile = saveFile.substring(saveFile.lastIndexOf("\\") + 1,saveFile.indexOf("\""));
//out.print("FileName:" + saveFile.toString());

//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;
saveFile = "C:\\temp\\jaga\\"+ saveFile;
FileOutputStream fileOut = new FileOutputStream(saveFile);


//fileOut.write(dataBytes);
fileOut.write(dataBytes, startPos, (endPos - startPos));
fileOut.flush();
fileOut.close();

out.println("File saved as " +saveFile);

Your code works well :-), except that it adds two extra bytes to the new file. Does anyone know why? If possible, can you add more comments to code. I really want to understand it.

Thanks a bunch.

Hi! I am doing on a function whereby you need to
1) do a UI
2) check if the file exists in the client
3) Upload the file to the server for example : c:/temp
5) read each row
6) for each row, get the data
7) update the database accordingly

hello everyone,

just wanted to ask when u upload a file to the server side,
is it necessary to read the contents of the file or you could just save the file onto the
server side...
if it is possible to just save the file on the server without reading the contents
then plz could someone tell me how to do this,

thanks in advance
moh
