Subject [jira] Commented: (AXIS2-3353) Use wrapper types when elements are optional (i.e.: nillable="true" or minOccurs="0"/maxOccurs="1")

Mauro Molinari commented on AXIS2-3353:
---------------------------------------

Hi Stein,
as stated by Amila, as of now you must use Java 5 to compile your code, because the generated
code uses the auto-(un)boxing feature.

I think this is only needed when you user -Euwc switch.

> As of now, Axis2 WSDL2Java uses some weird convetion about "null".
> I mean, when an element in a WSDL is marked as nillable="true" or minOccurs="0"/maxOccurs="1",
the generated Java code still uses primitives types such as int, double, short, long, float,
boolean.
> Because of this, I personally experienced (and also read about here in JIRA), Axis2 uses
the following questionable convention to handle null values:
> int, short, long => Integer.MIN_VALUE, Short.MIN_VALUE, Long. MIN_VALUE
> float, double => Float.NaN, Double.NaN
> boolean => false
> Actually, these values are NOT null.
> I think Axis2 should map optional elements of type xsd:int, xsd:double, xsd:float, xsd:short,
xsd:long, xsd:boolean to, respectively: Integer, Double, Float, Short, Long, Boolean and assign
null to them when they are specified as nil or when they are not specified in the SOAP message.
> If I understood it well, Axis1 did this, didn't it?
> At least, I think Axis2 should give an option to enable this and, IMHO, I also think
it should be on by default...
