Hi Everyone,
I came across na interesting situation here. One of my classes contains a
Boolean (wrapper) value as its return type. Something like this:
...
public Boolean isServerOK() {
return isOK;
}
...
Whenever I try to invoke this method using EL, I receive the following error:
"Property serverOK not found onm type package.path.MyClass". On the other hand,
if I change this method return type to boolean (primitive), I can run it
correctely.
Looking in Expression Languange Specification published at
https://jsp.dev.java.net/spec/jsp-2_1-fr-spec-el.pdf , I could find the
following item:
1.18.5
Coerce A to Boolean
■ If A is null or "", return false
■ Otherwise, if A is a Boolean, return A
■ Otherwise, if A is a String, and Boolean.valueOf(A) does not
throw an
exception, return it
My question is: Should I be able to use Boolean (wrapper) as a boolean
(primitive) yes or no?
Thanks a lot!
