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
The role is editor
The role is editor
So from point 1 and point 2
(See the expression is with in ${} point 1)
The role is editor
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
The role is editor
is same as
The role is editor

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:
Prints out the role fine
While the following statements are newer true:
Expression must be contained in ${ and } in its entirety i.e.
${role eq 'editor'}
The role is editor
${role ne 'editor'}
-Rahul
The role is editor
Where do I go wrong?
