Hi all,
I'm using a simple Unmarshaller to unmarshall a String into a Java
bean, using Castor v1.2:
Unmarshaller un = new Unmarshaller(MyObject.class);
Mapping mapping = new Mapping();
mapping.loadMapping(mappingFilePath);
un.setMapping(mapping);
MyBean myBean = un.unmarshal(new StringReader(myString));
My mapping file:
<?xml version="1.0" encoding="UTF-8"?>
<mapping>
<class name="com.MyBean">
<map-to xml="myBean" />
<field name="myField" type="string" />
[...]
</class>
</mapping>
When myString contains XML data corresponding to MyBean, the
unmarshalling works correctly.
But when myString is an empty String or does not contain XML data
corresponding to MyBean, I would expect myBean to be null or an
exception to be thrown. Instead, I get a newly instantiated MyBean,
with no fields set.
Is there a way to detect that no XML data corresponding to the bean
class was found in myString (like a "required" attribute on the
<class> tag?)?
I couldn't find anything in the documentation or in the mail archive
about this. Am I missing something?
I could parse the String myself, looking for a <myBean> tag, but I
would prefer the tag name to stay configurable in the Castor mapping
file.
Thanks in advance and many thanks for your great Castor library.
