Dear All,

I am looking for some help to find the exact XML / JSON document to
post to a resource.

- I have a DB with a 1 - N relationship, such as "PURCHASE" and
"CARD" (one purchase is made using a credit card)
- All DB IDs (primary keys) are auto generated
- I generated the corresponding Entity Beans
- I generated the corresponding REST resources

When testing the REST service,

- GET operation on PURCHASE is OK : I receive XML such as

<?xml version="1.0" encoding="UTF-8"?>
    <purchases uri="http://localhost:8080/iFidelity/resources/
purchases/">
        < purchase uri="http://localhost:8080/iFidelity/resources/purchases/3/
">
            <amount>30.000</amount>
            <buyDate>2009-06-05</buyDate>
            <cardId uri="http://localhost:8080/iFidelity/resources/purchases/3/cardId/
"/>
            <id>3</id>
        </purchase>
...
    </purchases >


- Question is : what is the correct format for POST statement,
creating a new PURCHASE while referring to an existing CARD ?
I tried several documents similar to

<?xml version="1.0" encoding="UTF-8"?>
    < purchases uri="http://localhost:8080/iFidelity/resources/purchases/
">
        <purchase uri="http://localhost:8080/iFidelity/resources/purchases
">
            <amount>30.000</amount>
            <buyDate>2009-06-05</buyDate>
            <cardId uri="http://localhost:8080/iFidelity/resources/cards/3/
">3</cardId>
        </purchase>
    </purchases>

  But they were all rejected with various exceptions ...

Could someone point me to the right syntax to POST to resources with a
1-N relationship ?

Thanks

Seb
