This is my Jsp code for image upload in database:
-----------Upload.jsp----------------
<html>
<head>
<title>Account Details </title>
</head>
<body bgproperties="fixed" bgcolor="#CCFFFF">
<form method="POST" action="UploadPicture.jsp" enctype="multiform/form-data">
<%! int update=0; %>
<%@ page import="java.util.*" %>
<%@ page import="java.sql.*" %>
<%@ page import="java.text.*" %>
<%@ page import="java.sql.Date" %>
<%@ page import="java.io.*"%>
<%@ page language = "java" %>
<%
try
{
String ct="3";
String path;
File image=new File(request.getParameter("upload"));
path=request.getParameter("upload");
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:itPlusElect ronics","","");
PreparedStatement pstmt=con.prepareStatement("insert into graphics values(?,?,?)");
pstmt.setString(2,path);
pstmt.setString(3,ct);
InputStream is=new FileInputStream(path);
pstmt.setBinaryStream(1, is, (int)(image.length()));
int s=pstmt.executeUpdate();
if(s>0)
{
out.println("Uploaded");
}
else
{
%>
unsucessfull
<%}
is.close();
pstmt.close();
}
catch(Exception e)
{
}%>
</p>
<p><br>
<img src="UploadedPicture.jsp">image</img>
<p></p>
</form>
</body>
</html>
-------------------------------------------------------------
My database name is itPlusElectronics and the table name is "graphics".
I have seen as a result of the above code that the image is stored in database as "Long binary data". and database table is look like as follows-------
picture path id
Long binary data D:\AMRIT\1-1-Picture.jpg 3
------------------------------------------------------------------------------
To retrive and display i use this JSP code as--
------------------------UploadedPicture.jsp------------------------------
<html>
<head>
<title>Account Details </title>
</head>
<body bgproperties="fixed" bgcolor="#CCFFFF">
<%! int update=0; %>
<%@ page import="java.util.*" %>
<%@ page import="java.sql.*" %>
<%@ page import="java.text.*" %>
<%@ page import="java.io.*"%>
<%@ page language = "java" %>
<%@page import="javax.servlet.ServletOutputStream"%>
<%
try
{
String path;
path=request.getParameter("upload1");
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:itPlusElect ronics","","");
PreparedStatement pst = con.prepareStatement("SELECT * FROM graphics WHERE id ='3'");
// pst.setString(3, id);
ResultSet rs = pst.executeQuery();
path=rs.getString("path");
if(rs.next()) {
byte[] bytearray = new byte[4096];
int size=0;
InputStream sImage;
sImage = rs.getBinaryStream(1);
response.reset();
response.setContentType("image/jpeg");
response.addHeader("Content-Disposition","filename=path");
while((size=sImage.read(bytearray))!= -1 )
{
response.getOutputStream().write(bytearray,0,size) ;
}
response.flushBuffer();
sImage.close();
rs.close();
}
}
catch(Exception e)
{
}
%>
</body>
</html>
