[castor-dev] Castor-JAXB Interoperability

Hello everyone,

I would like to extend / modify Castor to be enable it to unmarhal XML
that has been created by a JAXB reference implementation

but don't know where to start. I would be grateful if anyone could
provide an idea. Thanks in advance.

Motivation:

I'm currently facing a problem in unmarshalling XML that has been
created by a JAXB implementation with Castor.

I'm wondering if it is possible to do that without specifying any
Castor-Mapping information.

Basically with simple properties it works
(org.exolab.castor.xml.naming=mixed) but the problems arise when
collection types

are involved as the way collections are marshalled/unmarshalled in JAXB
and Castor are slightly different.

Demonstration:

JavaSrc:

...

private Map<Integer, Drink> drinkList;

...

public class Drink {

private String drinkName;

private Float price;

private int alcoholByVolume;

}

JAXB marshalling of JavaSrc:

...

<drinkList>

<entry>

<key>1</key>

<value>

<alcoholByVolume>0</alcoholByVolume>

<drinkName>Soda</drinkName>

<price>0.99</price>

</value>

</entry>

<entry>

<entry>

<key>2</key>

<value>

<alcoholByVolume>0</alcoholByVolume>

<drinkName>Tonic</drinkName>

<price>1.99</price>

</value>

</entry>

<entry>

</drinkList>

...

Castor produces something like this when marshalling in reflection-mode:

...

<drinkList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:java="http://java.sun.com"
xsi:type="java:org.exolab.castor.mapping.MapItem">

<key xsi:type="java:java.lang.Integer">1</key>

<value alcoholByVolume="0" xsi:type="java:collectionMapping.Drink">

<drinkName>Soda</drinkName>

<price>0.99</price>

</value>

</drinkList>

<drinkList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:java="http://java.sun.com"
xsi:type="java:org.exolab.castor.mapping.MapItem">

<key xsi:type="java:java.lang.Integer">2</key>

<value alcoholByVolume="0" xsi:type="java:collectionMapping.Drink">

<drinkName>Tonic</drinkName>

<price>1.99</price>

</value>

</drinkList>

...

Martin

Hi Martin,

we appreciate any effort to make Castor more compatible with JAXB.

I suggest you to create a new jira issue for the problem at hand a
attach a minimal test case to replay the problem. I think Werner, who is
the one familiar with that part of Castor, will take it from there.

Regards
Ralf
