Hi,
I'm having trouble with passing inheritance types. I've followed this
url:
http://www.ibm.com/developerworks/websphere/techjournal/0401_brown/brown.html
as a guide to WSDL inheritance, and everything seems to be working
except that when it comes time to do a typecast, there doesn't appear
to be any relationship of the objects...
I think it will be easier to explain the situation in code:
In my WSDL I have the following:
<simpleType name="idType">
<restriction base="xsd:string">
<enumeration value="INFNUM" />
<enumeration value="SESSNUM" />
<enumeration value="CLIENTCD" />
</restriction>
</simpleType>
<complexType name="idSet">
<sequence>
<element maxOccurs="1" minOccurs="1" name="idtype"
type="xsd1:idType" />
<element maxOccurs="1" minOccurs="1" name="idvalue"
type="xsd:string" />
</sequence>
</complexType>
<complexType name="idSetSess">
<complexContent>
<extension base="xsd1:idSet">
<sequence>
<element name="seqNum" type="xsd:string" />
</sequence>
</extension>
</complexContent>
</complexType>
.............
.............
<element name="get">
<complexType>
<sequence>
<element minOccurs="1" maxOccurs="unbounded" name="id"
nillable="true" type="xsd1:idSet" />
</sequence>
</complexType>
</element>
Then in my server code (the error is here):
public get(IdSet[] ids) {
...
for(int i = 0; i < id.length; i++) {
IdSet id = ids[i];
if(id.getIdtype() == IdType.SESSNUM) {
if(!(id instanceof IdSetSess))
throw new Exception("IdSetSess not used when IdType set to
SESSNUM!"); // XXX id should be an instance of IdSetSess
.....
.....
}
}
}
On the wire, an example request is:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";>
<soapenv:Body>
<xsd:get xmlns:xsd="http://osr.nsw.gov.au/pillar/gen/xsd";>
<xsd:id xsi:type="xsd:idSetSess"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<xsd:idtype>SESSNUM</xsd:idtype>
<xsd:idvalue>20004465</xsd:idvalue>
<xsd:seqNum>141</xsd:seqNum>
</xsd:id>
<xsd:id>
<xsd:idtype>INFNUM</xsd:idtype>
<xsd:idvalue>7151999517</xsd:idvalue>
</xsd:id>
</xsd:get>
</soapenv:Body>
</soapenv:Envelope>
The request on the wire looks to be to be OK. The expression "id
instanceof IdSetSess" is always false, whereas I would expect it to be
true.
Do I need to do something special to be able to cast an IdSet to an
IdSetSess? Is this even possible?
Cheers,
Matt.
