MOXy - specify element form in external bindings [message #812135]

Hi,

could anyone please tell me if it is possible to specify element form
using external bindings?

What I'm trying to achieve is mapping for the following example xsd
(showing just a fragment):

<schema targetNamespace="myNS"
elementFormDefault="qualified"
xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:tns="myNS">

<element name="MESSAGE" type="tns:SomeTypeName" />
<complexType name="SomeTypeName">
<sequence>
<element name="HEADER" type="tns:Header" form="unqualified" />
</sequence>
</complexType>

</schema>

I'd like to have an external mapping document that is able to produce
such a representation:

<m:MESSAGE>
<HEADER>
...
</HEADER>
</m:MESSAGE>

Root qualification should be addressed by <xml-ns> element in an
external binding document.

But how do I instruct MOXy that the HEADER element should be unqualified?

Thanks,
Tom

Hi Tom,

There looks to be a bug in our bindings file support with regards to this scenario, we have reproduced it and should have an update soon.

For what it's worth, the equivalent annotations do work:

[package-info.java]
@javax.xml.bind.annotation.XmlSchema(
xmlns = {
@javax.xml.bind.annotation.XmlNs(prefix = "m",
namespaceURI="myNS")
},
namespace = "myNs",
attributeFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED,
elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package example;

[Sample.java]
@XmlRootElement(name="MESSAGE",namespace="myNS")
public class Sample {

@XmlElement(name="HEADER",namespace="")
public String foo = "info";

}

Thanks,

I'm not sure if you got me right.

My problem is not that the root element does not get prefixed with the
one specified using <xml-ns>. For that I have entered a issue in
bugzilla (Bug 373159).

The thing is that I want an arbitrarily nested element to be specified
to be marshalled as 'local', i.e. not prefixed.

Say I have a schema (test.xsd):
<?xml version="1.0" encoding="UTF-8"?>
<schema elementFormDefault="qualified" attributeFormDefault="unqualified"
xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="test"
xmlns:tns="test">

<element name="ROOT" type="tns:TypeOfRoot"/>

<complexType name="TypeOfRoot">
<sequence>
<element name="ELEMENT_ONE" type="string"/>
<element name="ELEMENT_TWO" type="string" form="unqualified"/>
<element name="ELEMENT_THREE" type="string"/>
</sequence>
</complexType>
</schema>

Notice ELEMENT_TWO that has form="unqualified".

And this xml instance (text.xml):
<?xml version="1.0" encoding="UTF-8"?>
<t:ROOT xmlns:t="test"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="test test.xsd">
<t:ELEMENT_ONE>t:ELEMENT_ONE</t:ELEMENT_ONE>
<ELEMENT_TWO>ELEMENT_TWO</ELEMENT_TWO>
<t:ELEMENT_THREE>t:ELEMENT_THREE</t:ELEMENT_THREE>
</t:ROOT>

The xml above is valid. According to the schema ELEMENT_TWO cannot be
prefixed.

How do I specify external bindings so that MOXy produces the XML above
having an example class:

public class Root {
private String elementOne;
private String elementTwo;
private String elementThree;
}

Would this be the correct mapping?

<?xml version="1.0" encoding="UTF-8"?>
<xml-bindings
xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.eclipse.org/eclipselink/xsds/persistence/oxm http://www.eclipse.org/eclipselink/xsds/eclipselink_oxm_2_3.xsd"
version="2.3"
package-name="test">

<xml-schema
attribute-form-default="QUALIFIED"
element-form-default="QUALIFIED"
namespace="test">
<xml-ns namespace-uri="test" prefix="t"/>
</xml-schema>

<java-types>
<java-type name="test.Root">
<xml-root-element name="ROOT"/>
<xml-type prop-order="elementOne elementTwo elementThree"/>

<java-attributes>
<xml-element java-attribute="elementTwo" namespace=""/>
</java-attributes>
</java-type>
</java-types>
</xml-bindings>

Thanks,
Tom

Hi Tom,

Sorry for the confusion, I'm currently investigating 373159.

For this issue, yes, specifying namespace="" should achieve what you want. Was this not working for you? Below is the bindings.xml I used and the marshalled output:

<?xml version="1.0" encoding="UTF-8"?>
<xml-bindings ...>

    <xml-schema attribute-form-default="QUALIFIED"
        element-form-default="QUALIFIED" namespace="test">
        <xml-ns namespace-uri="test" prefix="t" />
    </xml-schema>

    <java-types>
        <java-type name="test.Root">
            <xml-root-element name="ROOT" />
            <xml-type prop-order="elementOne elementTwo elementThree" />
            <java-attributes>
                <xml-element java-attribute="elementOne" name="ELEMENT_ONE" />
                <xml-element java-attribute="elementTwo" name="ELEMENT_TWO" namespace="" />
                <xml-element java-attribute="elementThree" name="ELEMENT_THREE"/>
            </java-attributes>
        </java-type>
    </java-types>
</xml-bindings>

<?xml version="1.0" encoding="UTF-8"?>
<t:ROOT xmlns:t="test">
   <t:ELEMENT_ONE>1</t:ELEMENT_ONE>
   <ELEMENT_TWO>2</ELEMENT_TWO>
   <t:ELEMENT_THREE>3</t:ELEMENT_THREE>
</t:ROOT>

Thanks, that actually works. Somehow I couldn't get it to work at the
beginning - I was looking for 'form' option but then found that
specifying namespace='' achieves the expected result.
