Hi
Hi
I want to use Castor...but I am stuck while trying it out
Can you help me.......?
I Have an Object 'AipXMLContainer' which contains a collection of other
objects 'AipXml' I want to marshal this Object When I marshal the
AipXMLContainer I get following XML
<?xml version="1.0" encoding="UTF-8"?>
<aip-xMLContainer>
<aip-xmls
xsi:type="java:model.content_data_access.AIPOPImpl.AipXml"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<XML>src1.xml</XML>
<location>c:/temp</location>
<date>2003-03-02T06:24:33.597Z</date>
</aip-xmls>
<aip-xmls
xsi:type="java:model.content_data_access.AIPOPImpl.AipXml"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<XML>src2.xml</XML>
<location>c:/temp</location>
<date>2004-01-20T06:24:33.597Z</date>
</aip-xmls>
</aip-xMLContainer>
But when I try to unmarshal it I get following exception
ValidationException: element "aip-xmls" occurs more than once.
(XMLFieldDesciptor: aipXmls AS aip-xmls)

I am using following code to unmarshal it
Marshaller.marshal(container,writer);
Object object = Unmarshaller.unmarshal(AipXMLContainer.class,reader);
My Object is as following
---------------------------------------------------
package model.user_data_access;
/**

import java.util.*;
import model.content_data_access.AIPOPImpl.AipXml;
