[castor-user] question about dynamic mapping and AnyNode

Thu, 11 May 2006 05:21:57 -0700

Hello,

 

I’m trying to unmarshall an input XML file which contains a MessageHolder class. This class has a single class variable Object object.  Basically the MessageHolder can contain an Object of any type. So the XML input file could have a MessageHolder containing a simple String or something very complex like CustomerOrders.

 

<?xml version="1.0"?>

<mapping>

            <class name=" Root">

                        <map-to xml="data"/>

                        <field name="Id" type="java.lang.Integer">

                                    <bind-xml name="cmdId" node="element"/>

                        </field>

                        <field name="msgHolder" type="MessageHolder">

                                    <bind-xml name="get" />

                        </field>

            </class>

 

            <class name= "Get">

                        <field name="object">

                                    <bind-xml name="test" />

                        </field>

            </class>

 

            <class name=”CustomerDetails”>

                        <field name=”billingAddress” type =” BillingAddress” >

                                    <bind-xml name="billAddr"/>

                        </field>

                        <field name=”shippingAddress” type =” ShippingAddress” collection="set">

                                    <bind-xml name="shipAddr"/>

                        </field>

            </class>

 

            <class name=”CustomerOrders”>

                        <field name=”currentOrders” type =”CurrentOrders” collection="set">

                                    <bind-xml name="currOrders"/>

                        </field>

            </class>          

</mapping>

 

I tried to use the method suggested in http://www.codecomments.com/archive413-2006-1-749262.html

 

But the problem is that when I try to unmarshall the data stored in the XML file, the object stored in the MessageHolder object is returned as an instance of AnyNode.

 

ByteArrayInputStream bis = new ByteArrayInputStream(xml.getBytes());

Root root = (Root) unmar.unmarshal(new InputSource(bis));                      

MessageHolder messageHolder = (MessageHolder)root.getMessageHolder;

AnyNode actionObject = (AnyNode)messageHolder.getObject();

 

I would like to unmarshall the object as an instance of the actual class it belongs to eg CustomerOrders or CustomerDetails.

Is there any way to do this ?

 

Thanks for reading my question.

 

Best Regards,

Trish.
