Werner,
I'm sorry, but I still don't understand if it's possible to skip over the root
element when defining the highest level class. It also appears there's no way
to unmarshal a XML document that contains unmapped elements. In other words, I
want the following XPATH --> Class.property mappings.
/config/gateway/name --> Gateway.name
/config/gateway/url --> Gateway.url
/config/gateway/anotherField --> NO MAPPING
Unfortunately I continue to get "unable to find FieldDescriptor for 'gateway'
in ClassDescriptor of gateway" trying to skip over the root tag and map my
com.mypackage.Gateway class.
<config>
<gateway>
<name></name>
<url></url>
<anotherField></anotherField>
<action>
<name></name>
<ID></ID>
</action>
<action>
<name></name>
<ID></ID>
</action>
</gateway>
</config>
I tried using the root element as the bind mapping to my class in conjunction
with the location attribute like so...
<class name="com.mypackage.Gateway" auto-complete="false">
<map-to xml="config"/>
<field name="name" type="java.lang.String">
<bind-xml name="name" node="element" location="gateway"/>
</field>
</class>
but get "unable to find FieldDescriptor for 'anotherField' in ClassDescriptor
of gateway" for fields that are not described in the mapping document during
unmarshalling.

1) auto-complete:
*auto-complete*: if true, the class will be introspected to determine its field
and the fields specified in the mapping file will be used to override the field
found during the introspection.
2) location attribute:
The location attribute (as per
http://castor.org/xml-mapping.html#6.-Location-attribute) does exist in the
field mapping only. In other words, when specifying a field mapping for a
(collection) member, you might actually 'inject' an arbitrary XPATH prefix to
the actual field name (or corresponding XML name).
I hope this helps.
Werner

Betreff: Re: AW: [castor-user] XML binding
I thought I could control the "Castor XML introspector approach for all classes
not mapped" by setting the class "auto-complete attribute" to false. Is this
not the case?
The location attribute sounds like a great way to ignore elements in an
existing schema. This would definitely work for some of the lower elements,
but unfortunately this doesn't look like it works with the <map-to> element.
What I think I need is something like this:
<class name="com.mypackage.Gateway" auto-complete="false">
<map-to xml="config/gateway"/>
<field name="name" type="java.lang.String">
<bind-xml name="name" node="element"/>
</field>
</class>
or
<class name="com.mypackage.Gateway" auto-complete="false">
<map-to xml="gateway" location="config"/>
<field name="name" type="java.lang.String">
<bind-xml name="name" node="element"/>
</field>
</class>
Thanks,
Jon

Hi,
If you don't provide a mapping for all classes involved, Castor XML will use an
introspector approach for all classes not mapped (using some default naming
conventions for working out member names etc.).
To be honest, the error message 'unable to find FieldDescriptor for 'gateway'
in ClassDescriptor of gateway' somehow does not make sense, but this might be a
result of working in that 'mixed' mode.
Regards
Werner Guttmann
PS If you do not intend to provide a separate Java class (and a mapping) for
the <config> element, you might want to consider the use of the location
attribute (if applicable).
