  • Hint: what does the source of the generated page look like? – Matt Jacob Sep 12 '15 at 05:41

    @MattJacob sir, its just simple jsp page where i need to display the image as a profile picture.. i store the image on particular location and stored its name in database. then concat both and add it in session.. that session object is "imgurl" in my code. – Anand Deshmukh Sep 12 '15 at 05:53
  • I'm telling you to look at the source of the generated page. It's going to show `src="img"` because you haven't interpolated the variable into the template. – Matt Jacob Sep 12 '15 at 06:06

In your case src="img" will take soruce as "img".You can use Expression Language in jsp page as follow

<img src=${sessionScope.imageurl} alt=""  width="100" height="100"/>

    @AnandDeshmukh no, you didn't. The additional problem is that you're trying to use a file path instead of an http URL. You can't do that. Look at the generated HTML. It will contain something like ``. Assuming this was accepted by the browser (and it isn't): how can you know that the visitor of your web app is using windows, and has a G: drive containing these directories and files?

  • Your image path should contain http URL , otherwise it wont work. – Zaheer Khorajiya Sep 12 '15 at 07:27
