Hi,
U cannot do this directly thru JSP.
U will need to use a servlet for this and call the servlet in your <img> tag in your JSP.

The code for servlet is as follows:
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
* This is a servlet which renders an Image stored as a blob in the database.
public class BlobImages extends HttpServlet{
/**Process the HTTP Get request*/
public void doGet(HttpServletRequest request,HttpServletResponse response)
throws ServletException, IOException{
try{
//Calling the method getImage() to get the image from the database and rendering the same.
byte[] buffer =myDB.getImageData();
if(buffer != null){
response.getOutputStream().write(buffer,0,buffer.length);
} catch(Exception e){
Utilities.printStackTrace("BlobImages",e);
}//end of catch
}// end of method do GET
}// end of class
and the jsp tag will be as folows
<img src="http://localhost:7001/BlobImage">
