i have implement download when item name or data of second div clicked related data should downloaded.

can solve problem ?

how implement download in servlets end ?

i have write code imageservlet :

protected void doget( httpservletrequest request, httpservletresponse response) throws servletexception, ioexception      {            string id = request.getparameter("contact_id");              mysql myobj = new mysql();         myobj.connect();         printwriter out=response.getwriter();                try         {             string query="select photo contacts contact_id='"+id+"'";              resultset rs = myobj.getdata(query);              out.println(id);              blob image=null;             byte[] imgdata = null;             image= rs.getblob(1);             imgdata = image.getbytes(1, (int) image.length());             response.setcontenttype("image/gif");             outputstream o = response.getoutputstream();             o.write(imgdata);             o.flush();             o.close();              response.sendredirect("message.jsp");         }         catch (exception e)         {             e.getmessage();         }            }

you should use servlet serve image appropriate content-type header

<img src="img-servlet?contact_id=<%= rs.getint(1) %>"  width="500" height="300" alt="data">

and, in servlet contact_id query param , fetch image contents
