As of version 6, Java SE provides JAXB by which the bytes may be converted in to base64 string. Here also you may convert the image byte[] into base 64 string and it can be displayed using the html tag specifying the src data as base 64 i.e. src="data:image/png;base64,.

Modify your code as follows :

<%
            PreparedStatement ps=con.prepareStatement("select * from artist");
            ResultSet rs=ps.executeQuery();
            while(rs.next()){ %>
            
artist fast name:
<%=rs.getString(1) %>
 
                
artist middle name:
<%=rs.getString(2) %>
                
artist last name
<%=rs.getString(3) %>
                
artist job
<%=rs.getString(4) %>
                
artist image

                <%
                Blob bl=rs.getBlob(5);
                byte[] image=bl.getBytes(1, (int)bl.length());
                %>
                 
            
 
                <%
                }
                con.close();
          %>

Here is another sample jsp page for getting a clear idea :

<%@page import="java.awt.image.BufferedImage"%>
<%@page import="javax.imageio.ImageIO"%>
<%@page import="java.io.*"%>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>







<%
BufferedImage bImage = ImageIO.read(new File("/home/visruth/Desktop/Visruth.jpg"));//give the path of an image
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write( bImage, "jpg", baos );
baos.flush();
byte[] imageInByteArray = baos.toByteArray();
baos.close();
String b64 = javax.xml.bind.DatatypeConverter.printBase64Binary(imageInByteArray);
%>


    
As of v6, Java SE provides JAXB
