Hi All,
Firstly, i'm quite new to SOAP and webservices :-)
Here's my problem: I am trying to use a webservice (not mine) and
having trouble getting an array of objects. I think my problem lies in
defining the type mapping and serializers/deserializers for it.
I have been struggling with this for a while, any help is greatly
appreciated!
Thanks,
Christian
Heres part of the wsdl:
<!-- interface IHardDiskAttachment as struct: -->
<xsd:complexType name="IHardDiskAttachment">
<xsd:sequence>
<xsd:element name="hardDisk" type="xsd:string"/>
<xsd:element name="controller" type="vbox:DiskControllerType"/>
<xsd:element name="deviceNumber" type="xsd:int"/>
</xsd:sequence>
</xsd:complexType>
##### cut #####
<!-- collection IHardDiskAttachmentCollection as array (wsmap: struct): -->
<xsd:complexType name="ArrayOfIHardDiskAttachment">
<xsd:sequence>
<xsd:element name="array" minOccurs="0" maxOccurs="unbounded"
type="vbox:IHardDiskAttachment"/>
</xsd:sequence>
</xsd:complexType>
##### cut #####
Here's my java client code:
public IHardDisk getHardDisk(){
IHardDisk retCode = null;
try {
Call call = getCall();
call.setReturnClass(Vector.class);
TypeMappingRegistry registry =
call.getService().getTypeMappingRegistry();
TypeMapping mapping = registry.createTypeMapping();
QName IHardDiskAttachmentArrayTypeQname = new
QName(mor.getNameSpace(), "ArrayOfIHardDiskAttachment");
QName IHardDiskAttachmentArrayElementName = new
QName("", "array");
mapping.register(IHardDiskAttachment[].class,
IHardDiskAttachmentArrayTypeQname,
new
ArraySerializerFactory(IHardDiskAttachmentArrayTypeQname),
new
ArrayDeserializerFactory(IHardDiskAttachmentArrayTypeQname));
registry.register("ArrayOfIHardDiskAttachment", mapping);
IHardDiskAttachment[] disks =
(IHardDiskAttachment[])call.invoke(mor.getNameSpace(),
"IMachine_getHardDiskAttachments",
new Object[] { mor.getMOR() });
} catch (Exception e) {
e.printStackTrace();
}
return retCode;
}
I assume there are many places it is going wrong, lots of trial and
error :-/
Here's the SOAP response sent form the server:
HTTP/1.1 200 OK
