Thanks for quick reply Joshua. But I think it's not a good idea to include code in your POJO (i.e. postset method) that is too specific to JiBX..

Is there any other way to do this other than adding custom JiBX code to my POJO's?

Thanks

Thanks for the reply IIya.

Here is the binding file..

<?xml version="1.0" encoding="UTF-8"?>
<binding>
< mapping class="Person" name="person ">
     <value name="name" field="name"/>
     <collection field ="addresses" get-method="getAddresses" set-method ="setAddresses" type="java.util.HashSet">
              <structure map-as="Address"/>
      </collection>
</mapping>
<
mapping class="Address" name ="address">
     <value name="type" field ="type" style="attribute"/>

     <value name="street" field ="street"/>
</mapping>
</binding>

I don't know if I have to put something in the Address mapping to say that it has an association to Person.

I greatly appreciate your help!!

Thanks

Can you send us your JiBX binding file as well? I think you can just define two mappings and reference the address mapping within your person mapping. Your address mapping will then contain a structure for the person.

Either way, send us your mapping file and we'll take a look.

I am new to JiBX. I am trying to read an XML document, marshall it to Java Objects (POJO's) and persist them using hibernate.

Here's an example of what I am trying to do: A Person can have many addresses

<person>

         <name>Joe</name>

         <address type="home">

               <street>Home street</street>

         </address>

         <address type="business">

                <street>Office street</street>

         </address>

</person>

I have POJO's for Person and Address created (which are hibernate friendly)

public class Person {

         private string name;

         Set addresses;

         // No arg constructor

         // Getters and Setters etc.

}

public class Address {

        private string type;

        private string street;

        private Person addressFor;

        // No arg constructor

        // Getters and setters

}

When I use JiBX and marshall my XML document and try to persist it, I get an NullPointerException because the addressFor field in Address object is not getting set.

Any ideas on how I can do this?

I appreciate your help!!

Thanks
