Teneo support for QName [message #97463]

Tue, 25 September 2007 17:03

Eclipse User

Hi Martin,

I asked about QName in a previous posting, but it seem to have disappeared
from the newsgroup as it was an older posting.

Is there any chance that Teneo will support QName in it's schema
transformation? My xsd will convert to a schema without error if I change
my element to use string instead of Qname. But QName is not really just a
string. We are following a common specification in our development that
requires us to use QName. We can't use "string"

Here's an example of what the xml may look like:
<events:name
xmlns:x="http://com.bookstore.org/pages">x:switchPage</events:name>

Where xmlns:x="http://com.bookstore.org/pages" and x:switchPage would
probably need to be stored in database or something like this.

Is there around this?

Hi Julia,
Here is the old post:
http://dev.eclipse.org/newslists/news.eclipse.technology.emf t/msg02938.html

When you look at it at runtime what type of objects are used for QName, is it a String or another type?

If you have a small example (xsd plus small xml with testdata) then I can use this to solve this.

Based on this I can change the mapping logic so that Teneo will create a more precise mapping.

Hi Martin,

I'm not sure what you mean by what object QName is. The jdk docs
( http://ws.apache.org/commons/ws-commons-java5/apidocs/javax/ xml/namespace/QName.html)
show that you can extract QName as a string of different parts.

Hi Julia,
What I mean is when you load an xml/xmi document using an emf resource what class/object does EMF
then use to set this efeature (is it the javax.xml.namespace.QName you mention below)?

Martin,

EMF will generally uses org.eclipse.emf.ecore.xml.type.internal.QName to
construct an instance corresponding to a QName value. In EMF 2.3, this
implementation extends the native QName implementation from the JDK
available only for Java 5.0 and higher:

public final class QName extends javax.xml.namespace.QName
{

In 2.2, it does not extend anything. As the package name implies,
this class is internal and generally should not be used outside of the
EMF implementation. XMLTypeUtil provides accessor methods for
inspecting QName instances. In EMF 2.2, such instances were surfaced in
the API as java.lang.Object since we anticipated switching to the javax
version in the future. Now its surfaced as javax.xml.Qname.

Unfortunately QName itself is immutable and our implementation relied on
being able to set the prefix during serialization (when the mapping to
the namespace is used to deduce the right prefix). So our internal
implementation still provides that support. But minus that caveat,
clients can generally just use Java QName instances...

Hi Ed, thanks,

To solve this I probably need to make a specific mapping to jpox for Qname.

Julia, are you using EMF 2.2 or EMF 2.3?

Hi Julia,
Okay, you can enter a bugzilla for this but it may take a while before I have time to look at it.

So it is probably quicker to solve it yourselve:
To solve this you would have to create your own jpox type mapping class:
http://www.jpox.org/docs/1_1/extensions/usertypes.html

and then add the field-type attribute in the jdo file in the locations were the qname is used:
http://www.jpox.org/docs/1_1/metadata_reference.html#field
