set boolean value into variable using JSTL tags?

Question

I am using JSTL tags. i have below code.

Now variable refreshSent has boole

Answer 1

It is a String.

The following JSP code:

${refreshSent} : ${refreshSent['class']}
${refreshSent2} : ${refreshSent2['class']}
${refreshSent3} : ${refreshSent3['class']}

Outputs the following in a browser:

false : class java.lang.String
false : class java.lang.Boolean
false : class java.lang.String

But if you use the refreshSent variable in an EL expression where a boolean is expected, it will be converted to a boolean by a call to Boolean.valueOf(String) (according to the JSP Specification).

So if you use:

the value of the test attribute will be set to a boolean false value. The ${refreshSent} expression results in a String, but since the test attribute expects a boolean, a call to Boolean.valueOf("false") is made.
