[castor-user] Issues with mapping BigDecimal

[mnradhaki]

I have a class called Amount which implements IAmount.  It has one property
called "amount" which is of type java.math.BigDecimal.  This Amount class is
being referenced inside another class called SAP.  I use a mapping file. 
When I marshall the Java Object, I see the generated XML which has the
<amount>value</amount>, but when unmarhsalling it, I get the value as 0.  I
am pretty sure I am doing something wrong in the mapping.xml.  If I don't
specify the mapping.xml, then I get an error about balance(IAmount) does not
match with Amount.  Can someone please help me out here?

Here are the details:

public class SAP {
    private IAmount balance;
    public IAmount getBalance() {
        return balance;
    }

    public void setBalance(string amount) {
        balance = new Amount(amount);
    }
}

public class Amount implements IAmount {
    private BigDecimal amount;

    public Amount(String amount) {
        setAmount(amount)
    }

    public BigDecimal getAmount() {
        return amount;
    }
    public void setAmount(String amount) {
        this.amount = new BigDecimal(amount);
    }
}

public interface IAmount {
    public void setAmount(BigDecimal amount);
    public BigDecimal getAmount();
}

mapping.xml

<?xml version="1.0"?>

<!DOCTYPE mapping PUBLIC "-//EXOLAB/Castor Mapping DTD Version 1.0//EN"
                         "http://castor.org/mapping.dtd";>

<mapping>
  <class name="SAP" auto-complete="true">
      <map-to xml="data-object"
ns-uri="http://www.w3.org/2001/XMLSchema-instance";
           ns-prefix="xsi" />
   
    <field name="balance" type="IAmount">
      <bind-xml name="balance" node="element" />
    </field>
  </class>
</mapping>

Generated XML contains:

        <balance xsi:type="java:Amount">
            <amount>3469.78</amount>
        </balance>

Thanks,
Radha
