Thanks for reply Werner !
Actually I did couple of changes to make it work.
One change I did is I am creating an instance (new) of Unmarshaller
now,earlier I was using XMLContext for that.
As I understand from documentation, if mappings are being used then
Marshal/unmarshal should be created using XMLContext.
Yes, correct. If you are using the static methods of Unmarshaller, any
mapping will be ignored.
Is there any issue I
will be facing due to creation Unmarshaller instance going forward?
Not, not at all.

Werner
Please advice.
Thanks,

Hi Sam,
can you please change the class mapping for the Parent class as follows:
OLD:
<class name="com.demo.Parent">
<map-to xml="Parent" />
<field name="partners" type="com.demo.Partner"
collection="arraylist">
<bind-xml name="Partner" node="element" location="Parent" />
</field>
</class>
NEW:
<class name="com.demo.Parent">
<map-to xml="Parent" />
<field name="partners" type="com.demo.Partner"
collection="arraylist">
<bind-xml name="Partner" node="element" />
</field>
</class>
I simply removed the location attribute from the above<bind-xml/>. That
should remove your problem (as far as I can tell).
Cheers

Hi All-
I am a newbie to castor and facing an issue where in my arraylist is
empty
after unmarshal.
This is how my xml looks like,
1. Demo xml
<?xml version="1.0" encoding="UTF-8"?>
<Parent>
<Partner>
<person>
<firstname>Jason</firstname>
<lastname>Bong</lastname>
<gender>M</gender>
</person>
<address>
<line1>Addres 1</line1>
<city>City1</city>
<state>LA</state>
<zip>14323</zip>
</address>
</Partner>
<Partner>
<person>
<firstname>Bong</firstname>
<lastname>Jason</lastname>
<gender>M</gender>
</person>
<address>
<line1>1000 Drive</line1>
<line2>Address 2</line2>
<city>CIty2</city>
<state>LA</state>
<zip>12334</zip>
</address>
</Partner>
</Parent>
2. Mapping xml
<?xml version="1.0" encoding="UTF-8"?>
<mapping>
<class name="com.demo.Parent">
<map-to xml="Parent" />
<field name="partners" type="com.demo.Partner"
collection="arraylist">
<bind-xml name="Partner" node="element" location="Parent"
/>
</field>
</class>
<class name="com.demo.Address">
<map-to xml="address"/>
<field name="line2" type="java.lang.String">
<bind-xml name="line2" node="element" />
</field>
<field name="line1" type="java.lang.String">
<bind-xml name="line1" node="element" />
</field>
<field name="zip" type="java.lang.String">
<bind-xml name="zip" node="element" />
</field>
<field name="state" type="java.lang.String">
<bind-xml name="state" node="element" />
</field>
<field name="city" type="java.lang.String">
<bind-xml name="city" node="element" />
</field>
</class>
<class name="com.demo.Partner">
<map-to xml="Partner"/>
<field name="address" type="com.demo.Address">
<bind-xml name="address" node="element" />
</field>
<field name="person" type="com.demo.Person">
<bind-xml name="person" node="element" />
</field>
</class>
<class name="com.demo.Person">
<map-to xml="person"/>
<field name="gender" type="java.lang.String">
<bind-xml name="gender" node="element" />
</field>
<field name="lastname" type="java.lang.String">
<bind-xml name="lastname" node="element" />
</field>
<field name="firstname" type="java.lang.String">
<bind-xml name="firstname" node="element" />
</field>
</class>
</mapping>
Code snippet which I am using for unmarshal,
Unmarshaller um = xmlcontext.createUnmarshaller();
Parent parent=(Parent) um.unmarshal(new InputSource(new
FileReader("xml/Demo.xml")));
The exception which I am getting is, Class for root element 'parent' not
found.
If I use static method 'unmarshal' (Parent.class,"read xml from
stream"),the arraylist is empty.
Do I need to use descriptor classes here?
I guess I am missing something obvious.
Any help is appreciated.
Thanks,
Sam
