I have a problem in upload file using jsp.At localhost it is working file but at server when client upload a word document it is corrupted .A text file is uploaded successfully.

Please Help

Would be much helpful if you post your code or at least the crucial part as we are not good in mind reading :idea:

Thanks For reply.AT linux server the code is given below

<%@ page import="java.io.*" %>

String client=(String)session.getAttribute("clientid");
String contentType = request.getContentType();
FileOutputStream fileOut=null;
String file="";
String SaveFile="";
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;

 file = new String(dataBytes);
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;
pos = file.indexOf("filename=/"+1);

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;
String appPath = application.getRealPath("/")+"upload files/";  
    String dir2=appPath+client+"/";
  File f = new File(dir2);
	boolean ok = f.mkdirs();
	  String destFolder = dir2;  
saveFile= destFolder + saveFile; 
 fileOut = new FileOutputStream(saveFile);

fileOut.write(dataBytes, startPos,(endPos - startPos));

 catch (Exception e){    


Do NOT do any of that in JSP.

Plus consider using Apache Commons File Upload package rather than doing it yourself given the kind of nifty functionality it offers.
