Dynamic Image rendering on JSP page

Hi All!
I want to display images on my JSP page. However, the images should be generated dynamically (As are used by many sites during the registration process e.g., yahoo, etc..) How can i achieve this?
plz help! Its urgent!

HOWTO: Display a custom image on a jsp page

You need 4 files.
1. a jsp page (index.jsp)
2. A servlet (myPackage.ImageMaker)
3. A supplier class (myPackage.PluggableSupplier)
4. web.xml (your IDE should supply this)
From the jsp page you're calling the servlet with an <img> tag, and passing it some parameters.
The servlet obtains a BufferedImage from a pluggable supplier class, and returns with an image (png).
The image is displayed on the jsp page. Hope this helps!
================================================================================================
Here's the .jsp file (index.jsp)
<!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=UTF-8">
        <title>Image page</title>
    </head>
    <body>
    <h1>Your image:</h1>
    <img src="ImageMaker?Param1=Hello world&Param2=Hello again" />
    </body>
</html>================================================================================================
Here's the servlet (ImageMaker.java):
package myPackage;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.*;
import javax.imageio.ImageIO;
import javax.servlet.*;
import javax.servlet.http.*;
public class ImageMaker extends HttpServlet {
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        System.out.println("called");
        //Prevent chacing of the image as it's probably intended to be 'dynamic'
        response.addDateHeader("Expires", 795294400000L); //<--long ago
        response.addHeader("Cache-Control", "no-store, no-cache, must-revalidate, post-check=0, pre-check=0");
        response.addHeader("Pragma", "no-cache");
        //set mime type and get output stream
        response.setContentType("image/png");
        OutputStream out = response.getOutputStream();
        //catch incoming parameters, as many or few as you want
        String parameter1 = request.getParameter("Param1");
        String parameter2 = request.getParameter("Param2");
        //fetch the buffered image
        int width = 100;
        int height = 50;
        PluggableSupplier ps = new PluggableSupplier(width, height);
        BufferedImage buf = ps.fetchBI(parameter1);
        /***You can now draw on the original image if you want to add a watermark or label or whatever*********/
        Graphics g = buf.getGraphics();
        g.setColor(Color.BLACK);
        g.drawString(parameter2, 5, 30);
        try {
            System.out.println("writing...");
            ImageIO.write(buf, "png", out);
        } catch(IOException ioe) {
            System.err.println("Error writing image file: " + ioe);
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
}================================================================================================
This is the class that supplies your image (PluggableSupplier.java):
package myPackage;
import java.awt.Color;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
public class PluggableSupplier {
    BufferedImage buf = null;
    Graphics2D g2d = null;
    int width = 50;
    int height = 50;
    public PluggableSupplier(int w, int h) {
        if ((w+h)>2) {
            this.width = w;
            this.height = h;
        buf = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
        g2d = buf.createGraphics();
    public BufferedImage fetchBI(String parameter1) {
        if (g2d != null) {
            g2d.setColor(Color.RED);
            g2d.fillRect(0, 0, width, height);
            g2d.setColor(Color.WHITE);
            g2d.drawString(parameter1, 5, 15);
        return buf;
}================================================================================================
finally, your web.xml should look like this:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

        <servlet-class>myPackage.ImageMaker</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>ImageMaker</servlet-name>
        <url-pattern>/ImageMaker</url-pattern>
    </servlet-mapping>
    <session-config>
        <session-timeout>

    </session-config>
    <welcome-file-list>
     <welcome-file>
            index.jsp
        </welcome-file>
    </welcome-file-list>
</web-app>null

Another trick I learned (the hard way ;))...it's a good idea to buffer the output before responding. Add the following code to the servlet, in the case of the provided example, where all the other response-related stuff are done:
response.setBufferSize(yourBufferSize);It's a good idea to try and calculate the buffer size as accurately as possible.

Display Image in another jsp

hello,
I am facing a design issue of so as to how to go about displaying an image which i am retrieving from database.
I have a SubmitDoc.jsp which takes as input the doc id which i need to display looks like :
*SubmitDoc.jsp*
<FORM METHOD=POST ACTION="Retrieval">
Enter Document ID to Retrieve: <INPUT TYPE=TEXT NAME=DOCID SIZE=20/><BR>
<P><INPUT TYPE=SUBMIT></P>
</FORM>I have my Retrieval servlet which access the DB and gets the binary stream for the image data based on DOCID.
Now i try to forward result to a different jsp in order to display the binary data from the servlet.
something like this :
InputStream readImg = rs.getBinaryStream("DOCUMENT");
response.setContentType("image/jpg");
request.setAttribute("ImageData", readImg);
// response.getOutputStream().write(rb,0,len);
RequestDispatcher rd = request.getRequestDispatcher("DisplayDoc.jsp");
rd.forward( request, response );What code should i put in DisplayDoc.jsp to show the image there.
Any ideas how do i go about ?
Thanks,

What code should i put in DisplayDoc.jsp to show the image there.The same code you put in any html page to show an image:
<img src="urlToDownloadImageFrom"/>In effect you have two requests.
One for the JSP page, and then another for the image.
So often what you find is the tag on your page needs to pass the id as well
<img src="/ImageServlet?docId=abc123"/>

Displaying Japanese characters in JSP page

Hi,
I am calling an application which returns Japanese characters from my JSP. I am getting the captions in Japanese characters from the application and I am able to display the Japanese captions. After displaying the Japanese captions, user will select the particular captions by selecting the check box against the caption and Press Save button. Then I am storing the captions in the javascript string separated by :: and passing it to another JSP.
The acton JSP retrieves that string and split it by using tokenizer and store it in the database. When I retrieve it again from the database and display it, I am not able to see the Japanese characters, it is showing some other characters, may be characters encoded by ISO.
My database is UTF-8 enabled and in my server I am setting the UTF-8 as default encoding. In my JSP pages also, I am setting the charset and encoding type as UTF-8.
I shall appreciate you if you can help me in resolving the issue.

Post the encoding-related statements from your JSPs - there are a number of different ones that may be relevant.
It may also be relevant which database you store the strings in (Oracle, DB2, etc.), since some require an encoding parameter to be passed.

Display request contents in JSP page

i need to display the contents in a request in my JSP.
meaning:
i have a hashmap (containing string and a list) coming from the EJB tier to struts action in an event response object, I'm sure that the request has these values. cuz i tested it in struts action using the following code:
HashMap result = (HashMap)((EventResponseSupport)request.getAttribute(WebKeys.EVENT_RESPONSE)).getPayload();
System.out.println("Sponsor name = " + result.get("sponsor"));I am able to print it in the console but i need to know how to display it in the jsp. i tried many things but i can't get it right.
first i need to display the string and then i need to iterate through the list to display its contents in a table.
any help would be appreciated.

Kindly use JSP Scriplet to load the HashMap into the Page Context.
Then you can use the Struts iterate tags to paint the contents of the HashMap

Displaying calculated data in JSP pages

This is a general question about displaying data in JSP pages which has been calculated through ViewObj Routines. I have exposed the methods to the application level however, I want these methods to automatically run on the launch of the page. I can so this with a data action in the struts file. However, I have lots of these methods (all bringing single values of data), it seems inelegant to have 10 data actions or so. What's the best way to expose and show data on a JSP page automatically which has been calculated from the database rows.
Thanks in advance

You could convert the vo row to a hash using BeanUtils and then you could do what you want with it programmaticaly to automatically dissplay the lhash values.
