Hello
I made two servlet files and one web.xml as bellow:
ackage jp.wangsuya.testsample;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class Sample173 extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException{
response.setContentType("text/html;charset=Shift_JIS");
PrintWriter out = response.getWriter();
out.println
("<html<head><title>Sample173</title></head><body>");
out.println("<h2>�l�p�`�A�h��Ԃ�</h2>");
out.println("<p>");
out.println("<img src=\"Sample173jpeg\" border=1
width=300 height=150/>");
out.println("</body></html>");
out.close();
}
}
package jp.wangsuya.testsample;
import java.awt.BasicStroke;
import java.awt.Color;
import java.awt.Graphics2D;
import java.awt.Rectangle;
import java.awt.RenderingHints;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.sun.image.codec.jpeg.JPEGCodec;
import com.sun.image.codec.jpeg.JPEGImageEncoder;
public class Sample173jpeg extends HttpServlet {
public void doGet(HttpServletRequest request,HttpServletResponse
response)
throws ServletException, IOException{
response.setContentType("image/jpeg");
OutputStream out = response.getOutputStream();
BufferedImage img = new BufferedImage
(300,150,BufferedImage.TYPE_INT_RGB);
Graphics2D g2 = img.createGraphics();
g2.setRenderingHint
(RenderingHints.KEY_ANTIALIASING,RenderingHints.VALUE_ANTIALIAS_ON);
g2.setBackground(new Color(64,170,191));
g2.clearRect(0,0,300,150);
BasicStroke thickLine1=new BasicStroke
(5.0f,BasicStroke.CAP_BUTT,BasicStroke.JOIN_MITER,5.0f);
g2.setStroke(thickLine1);
g2.setPaint(Color.gray);
g2.fill(new Rectangle(30,30,200,80));
g2.setPaint(Color.red);
g2.draw(new Rectangle(30,30,200,80));
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
encoder.encode(img);
out.close();
}
}

When I runed servlet/sample173, the img did not show up. But when I runed
servlet/sample173jpeg, the img showed up. Could tell me why?

Please use the tomcat-user list for debugging code. The bug forum is not a
support group/general help desk.
When running Sample173 - the html printed is asking for an image called
Sample173jpeg, but the serlvet mapped is sample173jpeg - notice the case
difference in the beginning 'S'.
Please do not followup to this bug report, if you have more questios - use the
tomcat user list.
