Cannot differentiate between an int sent as 0 and an int sent as nil
--------------------------------------------------------------------
Key: AXIS2-1272
URL: http://issues.apache.org/jira/browse/AXIS2-1272
Project: Apache Axis 2.0 (Axis2)
Issue Type: Bug
Components: databinding
Affects Versions: nightly
Environment: Axis 2 nightly, Java 1.4.2, Tomcat 4
Reporter: Todd Doolittle
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!
