JSTL body content exact specification

Question

can someone suggest how possible to interpret body?

• One,Two,Three

Answer 1

There's no difference in the interpreted Java type of the c:set's body. It are in all cases just String.

Even when you set a non-String type as c:set's body using EL such as

${bean.someInteger}

it'll be converted to String anyway by String#valueOf().

Only when you process the variable afterwards, there may be difference, depending on how you processed it. For example,

One,Two,Three

will result ${realMovieArray} being a String[] with values of One, Two and Three.
