If you have used any technologies like tiles or common jsp pages like header footer then it will be one place you need to add. Otherwise no other way you will have to include the script tag in all Jsp pages if you have individual pages.

OR If you have any script file already included in all the file you include your js file in that JS file

by using normal script method you can attach

<script type="text/javascript" src="js/jquery.js"></script>

  • In every project try to have one header and footer file. then whatever change you want to do, you can easily access entire website by using single file. – Mani Jun 02 '16 at 10:21

Create your header file with script tag and more other common tags. Than include header into your page using:

<%@include file="header.jsp">

You can get more information about include here.

  • can i do it through filter class or by overriding any class ? – Jamsheer Jun 02 '16 at 10:33
  • In theory yes you can overwrite the response header with filter using i.e. a RequestDispatcher , but I dont have environment to test it. – HRgiger Jun 02 '16 at 10:46
