jaxp issue

[dufoli]

The code is inside cxf extension for quarkus. I try to fix the native support. But I am stuck on an issue with jaxp.
I have added a substitution to debug and my schema seems right but the namespace is not returned.

Utilisation of JAXP in native with Document()
Code executed
DOMSource domSource = new DOMSource(d);
StringWriter writer = new StringWriter();
StreamResult result = new StreamResult(writer);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = null;
try {
transformer = tf.newTransformer();
transformer.transform(domSource, result);
} catch (Exception e) {
}

    Logger LOG = LogUtils.getL7dLogger(org.apache.cxf.endpoint.dynamic.TypeClassInitializer.class);
    LOG.info("DOCUMENT :"+ writer.toString());
    LOG.info("DOCUMENT element :"+ d.getDocumentElement().toString());
    LOG.info("DOCUMENT namespace :"+ d.getDocumentElement().getNamespaceURI());

I have added many class which seems loaded by reflection in cxf or in jab jaxp but still failing.

Have you tried adding a dependency to quarkus-jaxp? as far as I can see, that extensions should be native ready already.
https://github.com/quarkusio/quarkus/tree/master/extensions/jaxp

[dufoli]

yes I have already added it ;-)

[dufoli]

the whole project is in https://github.com/dufoli/quarkus-cxf

I have nother exception upper:

@dufoli If I understand correctly, the problem is that d.getDocumentElement().getNamespaceURI() returns null, even though the namespace is set using xmlns:xs="http://www.w3.org/2001/XMLSchema".

I am myself not that familiar with jaxp / jaxb apis, but managed to find a place a bit earlier where the nsUri is returned as blank:
https://github.com/eclipse-ee4j/jaxb-ri/blob/master/jaxb-ri/txw/runtime/src/main/java/com/sun/xml/txw2/TXW.java#L59

(localname is schema, so that is the right tag).

I started a bit of cleanup in https://github.com/Postremus/quarkus-cxf/commits/try-fix-native-tests.

[dufoli]

hello @Postremus ,
thanks for help.
I have added proxy because of cxf:
https://github.com/apache/cxf/blob/dc2f6af9ad09888cafb350f95935e9ec6abf8aee/core/src/main/java/org/apache/cxf/common/jaxb/JAXBUtils.java#L1585

[dufoli]

OK, I have gone further...
issue is located in
com.sun.xml.bind.v2.schemagen.XmlSchemaGenerator.write
com.sun.xml.bind.v2.schemagen.XmlSchemaGenerator.Namespace.writeTo
com.sun.xml.bind.v2.schemagen.xmlschema.Schema._namespace
indeed com.sun.xml.bind.v2.schemagen.xmlschema.Schema implement TypedXmlWriter which is a proxy interface

com.sun.xml.txw2.ContainerElement handle the invoke method
I have declared TypedXmlWriter as proxy interface and all inherited interface too but it is still not enough.

[dufoli]

ok got the point. Indeed, I end exactly to the same place. So XMLNamespace target (package) must be loaded.
for (AnnotationInstance xmlNamespaceInstance : index.getAnnotations(DotName.createSimple("com.sun.xml.txw2.annotation.XmlNamespace"))) {
reflectiveClass.produce(new ReflectiveClassBuildItem(false, false, xmlNamespaceInstance.target().asClass().name().toString()));
}

[dufoli]

I have sent a pull request for that and few other things:
#13408

[geoand]

Is this still an issue?
