What I want to do is print the route of the host that I am currently on.

First code

Javascript code

var urlObt;

urlObt = window.location.href;

JSP Code

String url = "<script>document.write(urlObt)</script>";

Impression in href

Form 1

<link rel="stylesheet" href="<%=url%>/CSS/index.css">

Form 2

<link rel="stylesheet" href="<%=out.println(url)%>/CSS/index.css">

Result:

 http://localhost:8080/GIBLO/%3Cscript%3Edocument.write(urlObt)%3C/script%3E/CSS/index.css

Also try directly from the JSP

out.println(request.getAttribute("javax.servlet.forward.request_uri"));

But I came out null

javascript jsp

The JSP getRequestURL function allows you to obtain the url of the client that makes the request, in your case you can do something similar to this:

<% String url = request.getRequestURL();%>
<link rel="stylesheet" href="<%=url%>/CSS/index.css">
