Here is a code that upload an image on tomcat server and save it to database.


<%@ page language="java" %>
<HEAD><TITLE>Display file upload form to the user</TITLE></HEAD>
<BODY> <FORM ENCTYPE="multipart/form-data" ACTION="upload.jsp" METHOD=POST>
<table border="0" bgcolor=#ccFDDEE>
<td colspan="2" align="center"><B>UPLOAD THE FILE</B><center></td>
<td colspan="2" align="center"> </td>
<td><b>Choose the file To Upload:</b></td>
<td><INPUT NAME="file" TYPE="file"></td>
<td colspan="2" align="center"> </td>
<td colspan="2" align="center"><input type="submit" value="Send File"> </td>


<%@ page import="*" %>
<%@ page import="java.sql.*" %>
<%@ page import="*"%>
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 =, 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;
File ff = new File(saveFile);
FileOutputStream fileOut = new FileOutputStream(ff);
fileOut.write(dataBytes, startPos, (endPos - startPos));
%><Br><table border="2"><tr><td><b>You have successfully upload the file:</b>
<% out.println(saveFile);%></td></tr></table>
Connection connection = null;
String connectionURL = "jdbc:mysql://localhost:3306/test";
ResultSet rs = null;
PreparedStatement psmnt = null;
FileInputStream fis;
connection = DriverManager.getConnection(connectionURL, "root", "root");
File f = new File(saveFile);
psmnt = connection.prepareStatement("insert into image(images) values(?)");
fis = new FileInputStream(f);
psmnt.setBinaryStream(1, (InputStream)fis, (int)(f.length()));
int s = psmnt.executeUpdate();
System.out.println("Uploaded successfully !");
catch(Exception e){e.printStackTrace();}
