If the file is saved in public webcontent, then use JSTL <c:import> to display it.

<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
...
<pre><c:import url="file.txt" /></pre>

The <pre> tag is necessary so that newlines are been preserved in HTML output. Alternatives are adding CSS white-space: pre; to the containing element, or replacing \n with <br/>.

If the file is not saved in public webcontent, then create a servlet which gets an InputStream of it by FileInputStream and writes it to the OutputStream of the HttpServletResponse so that you can finally use <c:import> for this.
