>    Affects Versions: 1.4

> Hi guys,
>  I have the following problem - I have a simple bean with a property that starts with
an uppercase letter (e.g. ID).
> public class Person {
>     protected Integer id;
>     protected String name;
>     
>     public Integer getID() {  return id; }
>     public void setID(Integer id) { this.id = id; }
>     public String getName() { return name; }
>     public void setName(String name) { this.name = name; }
> }
> When I generate the schema element for it (using Java2WSDL), it's being generated with
lowercase - "iD":
> <xs:complexType name="Person">
>     <xs:sequence>
>         <xs:element minOccurs="0" name="iD" nillable="true" type="xs:int"/>
>         <xs:element minOccurs="0" name="name" nillable="true" type="xs:string"/>
>     </xs:sequence>
> </xs:complexType>
> That's not a problem by itself, the real problem, however, is that this property does
not get deserialized corectly on the server
> side and the service receives a person object with null ID:
> REQUEST:
> <ns2:inPerson>
>                <ns1:iD xmlns:ns1="http://data.test.tempuri.org/xsd">1</ns1:iD>
>                <ns1:name xmlns:ns1="http://data.test.tempuri.org/xsd">Detelin</ns1:name>
> </ns2:inPerson>
> RESPONSE:
> <ns:return xmlns:ax21="http://data.test.tempuri.org/xsd" type="org.tempuri.test.data.Person">
>                <ax21:iD xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"
/>
>                <ax21:name>Detelin</ax21:name>
> </ns:return>
> Notice that the returned "iD" property has not been initialized.
> I debugged the deserialization code on the server side and found out that the reason
for this seems to be in the
> org.apache.axis2.databinding.utils.BeanUtil#deserialize(Class, OMElement,ObjectSupplier,
String) method.
> The following code at line 429 of BeanUtil(revision 657751):
> PropertyDescriptor prty = (PropertyDescriptor)properties.remove(partsLocalName);
> is not finding the property descriptor since it searches using "iD" property name, while
the property descriptor name
> has been resolved by the java.beans.Introspector to "ID".
> Since the property descriptor is not found, the Person instance does not get its property
written and the service receives null,
> and hence the nil element in the response.
> Regards,
>    Detelin
