Using variable in expression language

Does anyone know if we can use variables defined in a scriptlet in a an expression language ?

For example, I defined the variable var as following:

<%! String var = "a variable"; %>

Then i try to test if this variable is equal to "a variable"

${var eq "a variable"}

this returns false, i guess the evalaution of the variable var returns null because EL are only looking for variables in any scopes but I am not sure ! That is why I am asking you this simple question.

If there is a special way to access those variable, let me know.

Thanks you in advance

Only implicit variables and variables defined in one of page,request,session or application scopes are available to EL.

So there is no special way to access these varuables unless you add them to some scope.
