[castor-dev] Force an element to be marshalled

Is there any way to force an element to be marshalled to XML even if the field in the Java object is null or empty?

I am marshalling XML to a remote web service that requires a CostCenter field in the XML, even if that field is null. Here is an example of the XML that is being produced:

<?xml version="1.0" encoding="UTF-8"?>
<Order>
<LineItem><ItemNumber>124029</ItemNumber><ItemQty>1</ItemQty><CostCenter>1234567.1234.123</CostCenter></LineItem>
<LineItem><ItemNumber>122094</ItemNumber><ItemQty>1</ItemQty></LineItem>
<LineItem><ItemNumber>119106</ItemNumber><ItemQty>1</ItemQty></LineItem>
<LineItem><ItemNumber>119105</ItemNumber><ItemQty>1</ItemQty></LineItem>
</Order>

Only the first <LineItem> includes the <CostCenter> element, but I need all of them to include it, even if it is an empty item i.e. <CostCenter></CostCenter>

Hi August,

if the following is an option to you, yes there is ....

<LineItem>
<ItemNumber>124029</ItemNumber>
<ItemQty>1</ItemQty>
<CostCenter xsi:nil=true" />
</LineItem>

I don't think the legacy system at the other end can handle elements like that. I actually solved the problem by forcing the value of the CostCenter field to be not-null in the Java Object. If you try to set the field to null, it uses "" instead:

protected String costCenter = "";

public void setCostCenter(String newValue) {
costCenter = (newValue == null) ? "" : newValue;
}

Hi August,

remember that you can always use a FieldHandler in order not to clutter
your POPOs.

Cheers
Werner

PS I think that you could have tried to suppress output of 'xsi:'
statements as well when marshalling, but it looks like you found a solution.
