Question

how to retrieve image from mysql database using java servlet and show it in HTML img tag? and also that ima tag should be placed inside a table definition ?

Answer 1

write a servlet, map it to a url like showImage.html, pass the imagename as param

<img src="showImage.html?filename=new.jpg">

Then read the byte[] from file and write to response OutputStream in the servlet code.

response.getOutputStream().write(bytes);

To get byte[] from file

 RandomAccessFile f = new RandomAccessFile("c:\images\pic1.png", "r");
 byte[] bytes = new byte[(int)f.length()];
 f.read(bytes);
 response.getOutputStream().write(bytes);
