Radu, Folks,

I am still struggling with Xmlbeans and namespaces, that is since before
the 23rd June. I know the XML Schema I have may not be 100% correct, but
it's not under my control as it is the clients.

I simply have to be able to control the prefixes used in code
generation. The autocreation of the namespace prefix by Xmlbeans is of
no use as the server side will not accept the XML documents created with
the XMLBeans prefix.

Is there no way (say in the xsdconfig) file that I can force a prefix
onto the QNames generated. The output from scomp shows:-

QName : URI "urn:xxxx/tML/Assurance.ServiceAction", localPart
ServiceInformationErrorInfo, prefix

where the prefix is blank. The prefix defined for this urn in the schema
is dt: whereas Xmlbeans creates ass:

I have to supply dt: there is no option for me. As the schemas use
derived types etc. there are all sorts of issues. I have spent hours and
hours on this and still cannot get suitable output to this problem. 

So to follow up on your comment Radu, 'Using the same prefix as the one
present in the Schema is interesting as an idea'. In my case here it's
not an idea the server enforces this and rejects XML that does not. This
may not be as per spec and a host of other reasons why it should, but
this is a real world project with all the issues that that presents.

Hoping for a miracle....

Regards

Don

Subject: RE: Namespace question type derivation causing issue

This is indeed caused by your use of type derivation, more specifically
by the way QName values work.
The problem that XmlBeans faces internally is that when you use a type
that's a derivation of the declared type (in your case DetailedFoo in
place of Foo), it needs to use an xsi:type attribute whose value is a
QName.
Because of the way QName values work, we need to declare a prefix in
order to insert one as text, *at the time you insert the value*. On the
other hand, the saveXXX() options work at the time you save the document
and basically the rule is that saving a document will not alter the
infoset. It is the interaction of these rules that makes so that you
can't use setSaveSuggestedPrefixes() to control the prefix used for the
value of xsi:type.

The solution to this would be to change setSaveSuggestedPrefixes() to
setSuggestedPrefixes() in other words to add a "newInstance" option
instead of a "save" option to control prefixes from the beggining. Using
the same prefix as the one present in the Schema is interesting as an
idea, but it would accomodate less use-cases and would require us to
persist the prefix value in the .xsd binaries, which we currently don't
do.

Okay I've progressed this (I think)

Where this is the output:-

        <dt:Parent>

            <dt:A/>

            <ass:Foo xmlns:ass="urn:bla/blabla/Assurance"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:type="ass:DetailedFoo">

            </ass:Foo>

            <dt:B/>

        </dt:Parent>

As I mentioned Foo is actually a DetailedFoo a derived type of Foo. I
created DetailedFoo and do an xmlText on the Document and its fine.
I add the DetailedFoo to the dt:Parent using Parent.setFoo() method
which appears on the cast to revert the namespace to <ass:Foo>. The
DetailedFoo type is defined in a separate schema which includes the
schema defining Foo. Both have the same namespace definition in their
respective schemas.

Regards

Don

A quickie,

I am presuming that the reason that the tag has had its namespace
redefined is that's it's from an included schema.

Can someone confirm this is the case.

Jacob,

Thanks for the response.

I also tried that in fact I've tried all the namespace functions in
different combinations, aprat from the correct one :o)

Hey Don,
I can't tell you why this happens, but I can suggest something to work
around it.
On your XmlOptions try setting
setAggressiveNamespace()
and  setSaveNamespacesFirst
<file:///H:/svn/xmlbeans/trunk/build/docs/reference/org/apache/xmlbeans/
XmlOptions.html#setSaveNamespacesFirst%28%29> () Good Luck, -Jacobd

        Hi,
         
        I'm getting an issue with namespaces that I cannot figure out.
My schema (read customers) defines a namespace:-
         
        xmlns:dt="urn:bla/blabla/Assurance"

         

        Without any XmlOptions I get :-

        <ass:Parent>

            <ass:A/>

            <ass:Foo xmlns:ass="urn:bla/blabla/Assurance"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:type="ass:DetailedBla">

            </ass:Bla>

            <ass:B/>

        </ass:Parent>

         

        When I generate I set the XmlOptions with :-

                XmlOptions xmlOptions = new XmlOptions();
                xmlOptions.setSavePrettyPrintIndent(4);
                xmlOptions.setSavePrettyPrintOffset(4);
                xmlOptions.setSavePrettyPrint();
                xmlOptions.setLoadLineNumbers();
                Map namespaceMap = new HashMap();
                namespaceMap.put("dt", "urn:bla/blabla/Assurance");
                xmlOptions.setLoadSubstituteNamespaces(namespaceMap);
                xmlOptions.setSaveImplicitNamespaces(namespaceMap);

         

        The prefix changes to <dt:Foo>

        All except one inner block that starts as <ass: where the
namespace is redefined to be the same.

        Now what differs in the generation is that Foo is a derived type
so its actually a DetailedFoo which I create using the
DetailedFoo.Factory.newInstance(xmlOptions) method passing in the same
XmlOptions as above i.e. with the namespace mapping that worked for all
the other tags. I then use a Parent.setFoo() method to add it to the
Parent XmlObject. This is because Parent has only a setFoo() and not a
Parent.setDetailedFoo().

        Can anyone tell me why I end up with :-

        <dt:Parent>

            <dt:A/>

            <ass:Foo xmlns:ass="urn:bla/blabla/Assurance"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:type="ass:DetailedFoo">

            </ass:Foo>

            <dt:B/>

        </dt:Parent>

         

        I realise that the redefinition of the element is causing it to
be redined but why is this sub-element not subject to remapping the same
as the other level. Anyone shed some light on this for me ??

         

        Many Thanks

         

        Don
