This trick sets HTML base to the root context path of the current webapp:
  1. The short version: 
    <!DOCTYPE html>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>
<html>
<head>
<c:set var="req" value="${pageContext.request}" />
<base href="${fn:replace(req.requestURL, req.requestURI, req.contextPath)}/" />
</head>
.
.
.
</html>

  2. The long version: 
    <!DOCTYPE html>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>
<html>
<head>
<c:set var="req" value="${pageContext.request}" />
<c:set var="http_base" value="${req.scheme}://${req.serverName}:${req.serverPort}${req.contextPath}/"/>
<base href="${pageContext.request.secure ? fn:replace(http_base, ':443/', '/') : fn:replace(http_base, ':80/', '/')}"/>
.
.
.
</html>
