Castor-dev,

Hello.

I’m using Castor-XML 0.9.5.2 and I’m having an issue using the <bind-xml location=””> feature. I know that you don’t provide support, but if you do have a chance to look at this issue I would appreciate it. I’m not sure if it’s a bug or an error on my part. I’ve attached the pertinent files. Briefly, I’m getting the following error when unmarshaling the XML file:

org.xml.sax.SAXException: unable to find FieldDescriptor for 'name' in ClassDescriptor of long-name

The snippet of XML data is:

<drugdata:drug drug-id="36" orphan="no" who-formulary="no">

<drugdata:long-name>

<drugdata:name>Acetaminophen; Chlorpheniramine Maleate; Hydrocodone Bitartrate; Phenylephrine Hydrochloride</drugdata:name>

</drugdata:long-name>

</drugdata:drug>

And the snippet of the XML mapping file is:

<map-to xml="drug" ns-prefix="drugdata"/>

<bind-xml name="name" node="element" location="long-name"/>

</field>

</class>

I think this should be easy, but I’ve not been able to determine the solution. If I change the name of the <drugdata:name> tag to simply <name>, then it works, but obviously I can’t do that. What am I missing in respect to declaring namespaces, so the “location” feature can recognize that <drugdata:long-name> contains a field called <drugdata:name>?

Here’s most of the Java code:

public class MDCImportIBN {

public MDCImportIBN() {

}

public static void main(String args[]) {

Mapping mapping = new Mapping();

try {

// 1. Load the mapping information from the file

mapping.loadMapping( "ibnmapping.xml" );

// 2. Unmarshal the data

Unmarshaller unmar = new Unmarshaller(mapping);

ExportContainer exportContainer = (ExportContainer)unmar.unmarshal(new InputSource(new FileReader("c:/mdc/xml/IBN/d000036.xml")));

// 3. Do some processing on the data

// 4. marshal the data with the changes and print the XML in the console

Marshaller marshaller = new Marshaller(new OutputStreamWriter(System.out));

marshaller.setMapping(mapping);

marshaller.marshal(exportContainer);

} catch (Exception e) {

System.out.println(e);

return;

}

Thanks,

Matt
