Hi Friend,
Try the following code:
1)page.jsp:
<HTML> <HEAD><TITLE>Display file upload form to the user</TITLE></HEAD> <BODY> <FORM ENCTYPE="multipart/form-data" ACTION="upload.jsp" METHOD=POST> <br><br><br> <center> <table border="0" bgcolor=#ccFDDEE> <tr><center><td colspan="2" align="center"><B>UPLOAD THE FILE</B><center></td></tr> <tr><td colspan="2" align="center"> </td></tr> <tr><td><b>Choose the file To Upload:</b></td><td><INPUT NAME="file" TYPE="file"></td></tr> <tr><td colspan="2" align="center"> </td></tr> <tr><td colspan="2" align="center"><input type="submit" value="Send File"> </td></tr> <table> </center> </FORM> </BODY> </HTML>
2)upload.jsp:
<%@ page import="java.io.*,java.sql.*" %>
<%
String saveFile="";
String contentType = request.getContentType();
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);
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=\"");
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:/UploadedFiles/"+saveFile;
File ff = new File(saveFile);
FileOutputStream fileOut = new FileOutputStream(ff);
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>

Connection connection = null;
String connectionURL = "jdbc:mysql://localhost:3306/test";

fis = new FileInputStream(f);
psmnt.setBinaryStream(1, (InputStream)fis, (int)(f.length()));
int s = psmnt.executeUpdate();
if(s>0) {
System.out.println("Uploaded successfully !");
}
else{
System.out.println("unsucessfull to upload file.");
}
}
catch(Exception e){e.printStackTrace();}
}
