The text as is from JSP 2.0 Spec

Point 1.
EL expression An element in a JSP page representing an expression to be parsed
and evaluated via the JSP Expression Language. Syntactically it is delimited
by the ${ and } characters.

Point 2.
JSP.2.3.5.5 Relational Operators
The relational operators are:
== and eq
!= and ne
< and lt
> and gt
<= and le
>= and ge

Point 3
JSP.2.3.5.7 A {==,!=,eq,ne} B
If A==B, apply operator
If A is null or B is null return false for == or eq, true for != or ne.
If A or B is BigDecimal, coerce both A and B to BigDecimal and then:
If operator is == or eq, return A.equals( B )
If  operator is != or ne, return !A.equals( B )
If A or B is Float or Double coerce both A and B to Double, apply operator
...

Your code
========
<c:if test="${role}==editor">
              The role is editor
        </c:if>

        <c:if test="${role}=='editor'">
              The role is editor
        </c:if>

So from point 1 and point 2

<c:if test="${role=='editor'}">  (See the expression is with in ${} point 1)
              The role is editor
        </c:if>
will work . See Point 2 bulleted points . == and eq and Point 3 how the relational operator is evaluated. You can look for more information in the spec.

So
<c:if test="${role=='editor'}">
              The role is editor
        </c:if>
is same as
<c:if test="${role eq 'editor'}">
              The role is editor
        </c:if>

I want to use JSTL to check the role of the user (it can be one of many)

I'm new to JSTL so even the simplest things gives me problems:

I've set the role using request.setAttribute("role" , role);

This tag:
<c:out value="${role}"/>

Prints out the role fine

While the following statements are newer true:

        <c:if test="${role}==editor">
<snip/>

Expression must be contained in ${ and } in its entirety i.e.

${role eq 'editor'}


              The role is editor
        </c:if>

        <c:if test="${role}=='editor'">
<snap/>

${role ne 'editor'}

              The role is editor
        </c:if>

Where do I go wrong?
