There's no "best", but it's good to know that JSP as being a view technology already provides the <jsp:include>
tag for this. E.g.
<!doctype html>
<html lang="en">
<head>
<title>SO question 2158749</title>
</head>
<body>
<jsp:include page="menu.jsp" />
<h1>Content</h1>
</body>
</html>
where in you can just code menu.jsp
as if it's a part of the parent page:
<ul>
<li><a href="home">Home</a></li>
<li><a href="faq">FAQ</a></li>
<li><a href="content">Content</a></li>
</ul>
There are two "standard" alternatives: the @include
directive and the JSTL <c:import>
tag.
The difference is that the @include
directive includes the page during compile time (thus it will happen only once), while the <jsp:include>
includes the page during runtime (which has actually the benefit that you can include another dynamic content).
Further is the difference of <c:import>
that it includes the generated output of the page and thus not the source code as both <jsp:include>
and @include
does. The major benefit of <c:import>
is however that you can include external resources this way. E.g.
<c:import url="http://google.com" />
