Amila Chinthaka Suriarachchi commented on AXIS2-4166:
-----------------------------------------------------
use -Euwc option. this generates Byte class instead of byte where you can use
min value.
> MIN_VALUEs for byte, short, int and long are used in corresponding wrapper
> classes to indicate null values. The nillable attribute should be used to
> indicate null values

> Key: AXIS2-4166
> URL: https://issues.apache.org/jira/browse/AXIS2-4166
> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: codegen
> Affects Versions: 1.4.1, 1.3
> Reporter: Heinz Pferschy
>
> The MIN_VALUEs for byte, short, int and long are used in corresponding
> wrapper classes to indicate null values. Therefore it is not possible to
> transport these MIN_VALUEs via SOAP.
> E.g. It is not possible to use the value -128 for a byte
> Example:
> -------------
> If the type in WSDL is defined as
> <xsd:simpleType name="LongValue">
> <xsd:restriction base="xsd:long"></xsd:restriction>
> </xsd:simpleType>
> the following modification of the generated source is necessary to allow
> serialization of Long.MIN_VALUE
> //Heinz Pferschy: bug fix to allow Long.MIN_VALUE
> // if (localLongValue==java.lang.Long.MIN_VALUE) {
> //
> // throw new org.apache.axis2.databinding.ADBException ("property
> value cannot be null!!");
> //
> // }
> // else {
> xmlWriter.writeCharacters
> (org.apache.axis2.databinding.utils.ConverterUtil.convertToString
> (localLongValue) );
> // }
> This bug is related to AXIS2-1272.
> The provided fix shouldn't use MIN_VALUEs for null values. The nillable
> attribute should be used to indicate null values
