Yes I have. The following JSP executes quite well. The problem I have is
converting the Byte array to a BufferedImage. Pls help Alan. I have
searched google and I'm still searching. I have Jason Hunter's book and
also Marty Hall's book.
<%@ page import = "com.sybase.jaguar.jcm.*" %>
<%@ page import = "java.sql.*" %>
<%@ page import = "com.sun.image.codec.jpeg.*" %>
<%@ page import = "java.awt.image.*" %>
<%@ page import = "java.awt.*" %>
<%
final int WIDTH = 150;
final int HEIGHT = 150;
String contentype = null;
contentype = request.getParameter("ctype");
if (contentype != null){
response.setContentType("image/jpeg");
String sql = "select photo_data from images where employee_number =
'92004'";
JCMCache cache = JCM.getCacheByName("SelfServiceDB");
Connection conn = cache.getConnection(JCMCache.JCM_WAIT);
Statement stmt = conn.createStatement();
java.io.OutputStream cout = response.getOutputStream();
ResultSet resultSet = stmt.executeQuery( sql );
while (resultSet.next()){
// byte[] bytearray = resultSet.getString(1).getBytes());
}
//cout.close();
// create a blank image
BufferedImage image = new
BufferedImage(WIDTH,HEIGHT,BufferedImage.TYPE_INT_RGB);
Graphics2D g2 = image.createGraphics();
g2.setColor(Color.yellow);
g2.fillRect(0,0,WIDTH,HEIGHT);
// encode the output to JPEG
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(cout);
encoder.encode(image);
cout.flush();
cout.close();
} else {
out.println("<html>");
out.println(" <head>");
out.println(" <title>Photo</title>");
out.println(" </head>");
out.println(" <body>");
out.println(" <h1>Photo</h1>");
out.println(" <img src=images.jsp?ctype=me>");
out.println(" <em>Photo</em>");
out.println(" </body>");
out.println("</html>");
}

is a plethora of resources on this ... any servlet book (including mine).
