How to get the base url in jsp?

You just need to do:

<link rel="stylesheet" type="text/css" href="css/style.css"/>

provided that you have style.css file in folder "css" near your .jsp file. You don't need to know the base URL for that, this will work with any base URL that leads to your .jsp file.

Try:

<c:url var="baseUri" value="/" />

Note that this will give you a relative url to the context.
