I'm working with eBay's LMS (Large Merchant Services) and kept running into
the error:
org.xml.sax.SAXException:
SimpleDeserializer encountered a child
element, which is NOT expected, in
something it was trying to
deserialize.
After alot of trial and error I traced
the problem down. It turns out this works:
<?xml version="1.0" encoding="UTF-8"?>
<BulkDataExchangeRequests xmlns="urn:ebay:apis:eBLBaseComponents">
<Header>
<Version>583</Version>
<SiteID>0</SiteID>
</Header>
<AddFixedPriceItemRequest xmlns="urn:ebay:apis:eBLBaseComponents">
while this (what I've been sending) doesn't:
<?xml version="1.0" encoding="UTF-8"?>
<BulkDataExchangeRequests xmlns="urn:ebay:apis:eBLBaseComponents">
<Header>
<Version>583</Version>
<SiteID>0</SiteID>
</Header>
<AddFixedPriceItemRequest>
The difference is
the xml namespace attribute on
the AddFixedPriceItemRequest . All of my XML is currently being marshalled via JAXB and I'm not sure what is
the best way to go about adding a second xmlns attribute to a different element in my file.
So that's
the question. How do I add an xmlns attribute to another element in JAXB?
UPDATE:
package ebay.apis.eblbasecomponents;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlType;
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "AddFixedPriceItemRequestType", propOrder = {
"item"
})
public class AddFixedPriceItemRequestType
extends AbstractRequestType
{
@XmlElement(name = "Item")
protected ItemType item;
public ItemType getItem() {
return item;
}
public void setItem(ItemType value) {
this.item = value;
}
}
Added class definition by request.
UPDATE 2: Edited
the above class like so to no effect:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(namespace = "urn:ebay:apis:eBLBaseComponents",
name = "AddFixedPriceItemRequestType", propOrder = {
"item"
})
public class AddFixedPriceItemRequestType
UPDATE 3: Here is a snippet of
the BulkDataExchangeRequestsType class. I tried throwing a namespace="urn:ebay:apis:eBLBaseComponents" into
the @XmlElement for AddFixedPriceItemRequest but it didn't do anything.
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "BulkDataExchangeRequestsType", propOrder = {
"header",
"addFixedPriceItemRequest"
})
public class BulkDataExchangeRequestsType {
@XmlElement(name = "Header")
protected MerchantDataRequestHeaderType header;
@XmlElement(name = "AddFixedPriceItemRequest")
protected List<AddFixedPriceItemRequestType> addFixedPriceItemRequest;
UPDATE 4: Here's
the hideous chunk of code that is updating
the xml after marshalling for me. This is currently working although I'm not particulary proud of it.
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.newDocument();
marshaller.marshal(request, doc);
NodeList nodes = doc.getChildNodes();
nodes = nodes.item(0).getChildNodes();
for(int i = 0; i < nodes.getLength(); i++){
Node node = nodes.item(i);
if (!node.getNodeName().equals("Header")){
((Element)node).setAttribute("xmlns", "urn:ebay:apis:eBLBaseComponents");
}
}
Update 5:
For anyone else that runs into this problem with eBay and wonders why -
The reasoning
behind this most likely has to do with how eBay is handling these requests.
The BulkDataExchange probably takes
the XML payload, breaks it up, and send
the pieces out to
the Merchant or Trading API.
The inner pieces of
the payload then do not have
the namespace and
the get
the error. This is a guess on my part but I wouldn't be surprised if this is what was going on
behind the scenes.
Thanks for all
the help everyone.
