Amila Chinthaka Suriarachchi resolved AXIS2-1272.
-------------------------------------------------
Resolution: Fixed
set the MIN_VALUE in corresponding wrapper classes as the null value for
long,int,short and byte .
set the NaN in corresponding wrapper classes as the null value for float and
double. Now it is possible to handle null values even with the primitives.
> Cannot differentiate between an int sent as 0 and an int sent as nil

> Key: AXIS2-1272
> URL: https://issues.apache.org/jira/browse/AXIS2-1272
> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: adb, databinding
> Affects Versions: nightly
> Environment: Axis 2 nightly, Java 1.4.2, Tomcat 4
> Reporter: Todd Doolittle
> Assigned To: Amila Chinthaka Suriarachchi
>
> The service I deal with often sends back values a nil (or NULL). For most
> datatypes, such as String and Date the value of the object is NULL (using
> client code generated by WSDL2JAVA). However for anything that is an
> integer, it is set to 0. This makes it impossible to tell if the value in
> the message was really a 0, or if it was nil="true".
> For example, the type in the wsdl is defined as...
> <xsd:element name="response">
> <xsd:complextType>
> <xsd:sequence>
> <xsd:element name="firstNumber" type="xsd:int"/>
> <xsd:element name="secondNumber" type="xsd:int"/>
> </xsd:sequence>
> </xsd:complexType>
> </xsd:element>
> The server returns this response...
> <response>
> <firstNumber>0</firstNumber>
> <secondNumber nil="true"/>
> </response>
> In the client code, response.getFirstNumber() would return 0, and
> response.getSecondNumber() would also return 0.
> To get around this could we do one of the following...
> **When an int is returned from a service as nil="true" set the value to
> Integer.MIN_VALUE.
> or
> **In the generated classes using java.lang.Integer instead of int and in the
> case of a nil="true" response, set the Integer object to null.
> or
> **In the generated classes, for each int value include a isNull() method that
> would return a boolean.
> Thanks!
