How to display a buffered image in a jsp page?
Hai guys, I have a java page and there is a buffered image in it. I want to pass this buffered image into a jsp page and i want to display it there. Guys so pls help me to do it. I am new in java. so help me with simple codes. Thanks in adva开发者_Python百科nce.
you can write buffered image to some public web space and provide src to that in img tag
provide src as servlet and output the image directly from the servlet

- Example from BalusC blog
Here is a sample program taken from this post. It works fine.
<%@page import="java.awt.image.BufferedImage"%>
<%@page import="javax.imageio.ImageIO"%>
<%@page import="java.io.*"%>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<%
BufferedImage bImage = ImageIO.read(new File("/home/visruth/Desktop/Visruth.jpg"));//give the path of an image
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write( bImage, "jpg", baos );
baos.flush();
byte[] imageInByteArray = baos.toByteArray();
baos.close();
String b64 = javax.xml.bind.DatatypeConverter.printBase64Binary(imageInByteArray);
%>
<div>
<p>As of v6, Java SE provides JAXB</p>
<img src="data:image/jpg;base64, <%=b64%>" alt="Visruth.jpg not found" />
</div>
</body>
</html>
