Using jstl I want to list each letter of the alphabet.

I want something like a b ... z

Ok, no scriptlet. How about a JSP expression? If you don't want either of them, then you can create a custom EL function. Look near bottom of Hidden features of JSP/Servlet 

<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>  
<c:forEach var="i" begin="97" end="122">
    <%=Character.toChars((Integer)pageContext.getAttribute("i"))%>
</c:forEach>

Assuming you can inject java directly in (I don't know JSTL) you could do this

for(char letter = 'a'; letter <= 'z'; letter++) {
    System.out.println(letter + " ");
}

keeping in mind that a char is just an unsigned integer.

  • I am not allowed to inject Java scriptlets directly in the code. I'm not saying it is a reasonable restriction, but it is the restriction I am working under. – Joe Mar 26 '12 at 17:58
