Question

I have created a simple type

   <xsd:simpleType name="IntOrBlank">
            <xsd:union memberTypes="xsd:int">
                <xsd:simpleType>
                    <xsd:restriction base="xsd:string">
                        <xsd:enumeration value=""/>
                    </xsd:restriction>
                </xsd:simpleType>
            </xsd:union>
        </xsd:simpleType>

I then create stubs using wsdl2java from axis2, the sending works and receiving seemed to work until I try to obtain the integer value from this type. My code is as such:

IntOrBlank get_part_custom_field7 = each_record[0].get_part_custom_field7();
Object object = get_part_custom_field7.getObject();

The object is null now. eventhough the SOAP message is coming in as

   <bm:_part_custom_field7>9</bm:_part_custom_field7>

Answer 1

I trace through the code and I found that wsdl2java has generated the stubs incorrectly. The object that was created was java.math.BigInteger while the stubs did a check to make sure the object is an instance of Integer, as a result, the object is null without throwing any exception. I changed the type to

  <xsd:simpleType name="IntOrBlank">
        <xsd:union memberTypes="xsd:integer">
            <xsd:simpleType>
                <xsd:restriction base="xsd:string">
                    <xsd:enumeration value=""/>
                </xsd:restriction>
            </xsd:simpleType>
        </xsd:union>
    </xsd:simpleType>

and solved the problem
