how to get the context information

Posted: Apr 5, 2002 10:13 AM

Hi,

It may be a small problem but from my jsp page, I need to get the base URL information. For example if I am running my web application in localhost , I need
http://localhost:8080/myapp

How do we do this ?

I was trying <%= request.getServerName() %>
and <%= request.getServletContext()%>

but all had some or the other problem. It is not fixed, what I want is fixed base URL always.

Bye
Binod

String contextPath = request.getServletPath();
String requestURL = ( new HttpUtils().getRequestURL(request) ).toString();
String hostContext = requestURL.substring(0, requestURL.indexOf(contextPath) );

If you have a newer version of Servlet package, (HttpUtils is deprecated as of 2.3 API) use this:

String requestURL =  (request.getRequestURL()).toString();
