There seems to be an issue with AbstractMessageReader.getValueAsXXX()
methods when there is an empty element in the request. I am using 1.0
verion of xfire.
If I have a class like the following is passed to a service method as an
input parameter
public class A
{
private Long ID;
private Date createdDate;
private String name;
//getter and setter
}
Whose schema in wsdl looks like:
<xsd:complexType name="A">
<xsd:sequence>
<xsd:element minOccurs="0" name="ID" nillable="true"
type="xsd:long"/>
<xsd:element minOccurs="0" name="createdDate"
type="xsd:dateTime"/>
<xsd:element minOccurs="0" name="name" nillable="true"
type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
and created a request (using a php client) that could look like
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:ns1="http://mycompany.com";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<SOAP-ENV:Body>
<ns1:serviceMethod>
<ns1:A>
*<ns1:ID/>*
<ns1:createdDate>2006-07-01T00:00:00</ns1:createdDate>
<ns1:name>Chicago Cars</ns1:name>
</ns1:A>
</ns1:addCampaign>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
I get an exception:

I would expect either the request to go through or a
NumberFormatException because of an empty string. The issue seems to be
with AbstractMessageReader.getValueAsXXX() methods.
public long getValueAsLong()
{
if (getValue() == null) return 0l;
return Long.parseLong( *getValue()* );
}
The second getValue() is getting the value of the next element in the
request, in this case the value of the element createdDate.
The simple fix I can think of is to call getValue() once and use the text.
It would also be more practical and helpful (especially with interop
clients) to return null instead of NumberFormatException for empty
strings. I am not sure if this would violate any specs requirements.
