I want to concatenate 2 vars into a string in EL but since one is a

both to be
Longs so it can do arithmetic addition instead.
You could set a string variable this way:
<c:set var="myStringVariable"><c:out value="${category.id}"/></c:set>
That's not quite the minimalist approach I was thinking of, but it is one
approach.
Anyway I wonder what does it prevent you from using <c:url> and <c:param>...
To keep the JSP short and clear. Instead of these tags:
<c:url value="edit.html" var="url1">
<c:param name="category.id">${category.id}</c:param>
</c:url>
<a href="${url1}">xxxxx......</a>
do it with JSTL-EL:
<a href="${pc:url(pc:concat('edit.html?category.id=', category.id))}">
