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.
This might be worth having a look at. Can you please raise a Jira issue
over at http://jira.codehaus.org/browse/CASTOR and attach a working test
case that we can use to replay the problem.
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?
There's an option named 'ignoreExtraElements', but that's not really
what you are looking for. This could be used to throw an exception if
there's XML content to be parsed/unmarshalled which is not expected.
Other than that ... there's nothing right now.

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.
