UBL 2.1 unused namespace #25

patricksan · 2020-03-05T09:32:38Z

Dear,

First of all, thanks for your library.

I'm generating one invoice, but I noticed that one namespace is added without being used in the xml:

<?xml version="1.0" encoding="UTF-8"?>
<Invoice xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2" 
          xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2"
          xmlns:cec="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2"
          xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">
    <cbc:UBLVersionID>2.1</cbc:UBLVersionID>
    ....
    ....
    
</Invoice>

The xmlns:cec="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2" is added as namespace, but there is no reference of cec in the xml.

I'm saving the file using these lines:

var status = UBL21Writer.invoice().write(ublInvoice, file);

Is that a bug?

I'm using: JAVA 11 with ph-ubl 6.2.0

Thank you

@phax, I tried this, but it didn't work:

MapBasedNamespaceContext context = UBL21NamespaceContext.getInstance().getClone();
context.removeMapping("urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2");
writer.setNamespaceContext(context);

var status = writer.write(ublInvoice, file);

Also this:

final MapBasedNamespaceContext context = UBL21NamespaceContext.getInstance().getClone();
context.clear();
context.addDefaultNamespaceURI("urn:oasis:names:specification:ubl:schema:xsd:Invoice-2");
context.addMapping("cac", "urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2");
context.addMapping("cbc", "urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2");
writer.setNamespaceContext(context);

var status = writer.write(ublInvoice, file);

links to #10

phax · 2020-03-05T13:59:49Z

Try

MapBasedNamespaceContext context = UBL21NamespaceContext.getInstance().getClone();
context.removeMapping("cec");
writer.setNamespaceContext(context);

patricksan · 2020-03-05T15:13:55Z

Thanks @phax
I get this exception:

Caused by: java.lang.IllegalStateException: Internal inconsistency removing 'cec' and 'urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2'
	at com.helger.xml.namespace.MapBasedNamespaceContext.removeMapping(MapBasedNamespaceContext.java:244)

I tried to use getInstance() instead of getInstance().getClone(). It works in the sense to remove the cec namespace but it adds another one:

xmlns:ns2="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2"

phax · 2020-03-05T15:51:52Z

Okay, I can now reproduce the internal error - I will look at this one separately.
Basically: never modify the singleton UBL21NamespaceContext.getInstance() - only modify clones.

The system adds the ns2 prefix most likely, because your UBL contains an element that needs the urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2 namespace URI....?
Can you paste the full document here?

patricksan · 2020-03-05T16:06:36Z

Thanks @phax for the support.

The file doesn't contain the ns2. You can see the file here:

In my example generated there is no cec.

I see that your code (UBL21NamespaceContext), you initialise:

  protected UBL21NamespaceContext ()
  {
    addMapping ("xsi", XMLConstants.W3C_XML_SCHEMA_INSTANCE_NS_URI);
    addMapping ("xs", XMLConstants.W3C_XML_SCHEMA_NS_URI);
    addMapping ("cac", CUBL21.XML_SCHEMA_CAC_NAMESPACE_URL);
    addMapping ("cbc", CUBL21.XML_SCHEMA_CBC_NAMESPACE_URL);
    addMapping ("cec", CUBL21.XML_SCHEMA_CEC_NAMESPACE_URL);
    addMapping ("ds", CXMLDSig.NAMESPACE_URI);
  }

But cec is not removed when not present.

phax · 2020-03-05T16:14:47Z

That is indeed weird. Well the underlying XML "text" is created by JAXB and we only have limited control over it. So if you remove the "cec" mapping, but JAXB creates the "ns2" namespace prefix, I don't know why:

var writer = UBL21Writer.invoice();
MapBasedNamespaceContext context = UBL21NamespaceContext.getInstance().getClone();
context.removeMapping("cec");
writer.setNamespaceContext(context);

var status = writer.write(ublInvoice, file);

Ah you are using Java 10 or newer??? Are you including JAXB 2.3.x in your code?

patricksan · 2020-03-06T08:18:28Z

Hi @phax ,

We are using Java 11 ( oracle 11.0.5)
In our classpath we have JAXB 2.3.2

I noticed that you create and already close a bug #17.
Is it automatically deployed to Maven Repository?

phax · 2020-03-06T14:22:55Z

#17 is still open. Can you explain to be if UBL.PE still requires UBL 2.0 or whether everything is on UBL 2.1 now? My spanish is a bit poor ;-)

patricksan · 2020-03-06T14:58:00Z

Sorry @phax, I meant phax/ph-commons#17.
This one you closed. The open item #17 I have no knowledge about it.

My Spanish is also poor. But I think I could help if you give more details. :-)

phax · 2020-03-06T15:03:05Z

Ah okay - no release for that one yet.
That is an edge case that only occurs, if you modify the singleton directly (so don't call "removeMapping" directory on UBL21NamespaceContext.getInstance()) - if you remove only on the "clone" you are fine.

patricksan · 2020-03-06T15:17:43Z

Hi @phax, if I use the getClone() as I added in previous message, we get this exception:

Caused by: java.lang.IllegalStateException: Internal inconsistency removing 'cec' and 'urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2'
	at com.helger.xml.namespace.MapBasedNamespaceContext.removeMapping(MapBasedNamespaceContext.java:244)

That is why I asked about the release.
