Answer 1

If the rs.getString("file_path") returns a path is /home/Desktop/output/something.jpeg means you cannot download.Because when you click the given link surely it will show PAGE NOT FOUND (404) Exception.

"> click here to download the file

please note your URL it will look like

http://localhost:8080/prjname/home/Desktop/output/something.jpeg

So in this situation we can pass the path into one servlet ,through this servlet we can download the file.

 <%@ page import="java.io.*,java.sql.*"%>

   String id=request.getParameter("id");
   Class.forName("com.mysql.jdbc.Driver").newInstance();

   Statement st=con.createStatement();
   ResultSet rs=st.executeQuery("Select id,file_path,file_date from file12 where id like '"+id+"%'"); 
   %>
  <table cellpadding="15" border="1">
  <%
    while(rs.next()){
  %>
  <tr>
    <td><a href="<%=rs.getString("file_path")%>"> click here to download the file with  id :<%=rs.getString("id")%> </a> </td>

    </tr>
