Hi,
I am using EMF to generate the model code based on schema file sip-app_1_1.xsd
since the sip-app.xsd import web-app_2_5.xsd, so the framework generated 2 sets of classes for me.
one is in namespce http://www.jcp.org/xml/ns/sipservlet
another in namespace http://java.sun.com/xml/ns/javaee
these xsd files are all standards schema files.
sip-app_1_1.xsd:
----------------------
<xs:schema xmlns="http://www.jcp.org/xml/ns/sipservlet"
targetNamespace="http://www.jcp.org/xml/ns/sipservlet"
xmlns:javaee="http://java.sun.com/xml/ns/javaee"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"
version="1.1">
<xs:import namespace="http://java.sun.com/xml/ns/javaee" schemaLocation="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"/>
...
web-app_2_5.xsd
----------------------
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://java.sun.com/xml/ns/javaee"
xmlns:javaee="http://java.sun.com/xml/ns/javaee"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"
attributeFormDefault="unqualified"
version="2.5">
I want to use the genered code for a sip.xml generation application.
The problem here is (shows as b bloew generated sip.xml)
For the element that defined in javaee namespace, it always have a prefix "javaee:"
<?xml version="1.0" encoding="UTF-8"?>
<sip-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.jcp.org/xml/ns/sipservlet"
xmlns:javaee="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://www.jcp.org/xml/ns/sipservlet http://www.jcp.org/xml/ns/sipservlet/sip-app_1_1.xsd"
version="1.1">
<servlet-selection>
<main-servlet>ServletName</main-servlet>
</servlet-selection>
<servlet>
<javaee:description>Desc</javaee:description>
<javaee:servlet-name>ServletName</javaee:servlet-name>
<javaee:servlet-class>ServletName</javaee:servlet-class>
<javaee:init-param>
<javaee:description>d</javaee:description>
<javaee:param-name>n</javaee:param-name>
<javaee:param-value>v</javaee:param-value>
</javaee:init-param>
</servlet>
</sip-app>
To remove these prefix, I tried add a extended metadata as bleow:
final ExtendedMetaData ext = new BasicExtendedMetaData(
ExtendedMetaData.ANNOTATION_URI,
EPackage.Registry.INSTANCE, new HashMap());
ext.setQualified(JavaeePackage.eINSTANCE, false);
it works, the result as below:
<?xml version="1.0" encoding="UTF-8"?>
<sip-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.jcp.org/xml/ns/sipservlet"
xsi:schemaLocation="http://www.jcp.org/xml/ns/sipservlet http://www.jcp.org/xml/ns/sipservlet/sip-app_1_1.xsd"
version="1.1">
<servlet-selection>
<main-servlet>ServletName</main-servlet>
</servlet-selection>
<servlet>
<description>desc</description>
<servlet-name>ServletName</servlet-name>
<servlet-class>ServletName</servlet-class>
<init-param>
<description>d</description>
<param-name>n</param-name>
<param-value>v</param-value>
</init-param>
</servlet>
</sip-app>
But if try to load the file back, exception thrown.
Caused by: org.eclipse.emf.ecore.xmi.FeatureNotFoundException: Feature 'description' not found. (
at org.eclipse.emf.ecore.xmi.impl.XMLHandler.reportUnknownFeatu re(XMLHandler.java:1991)
so My questions are:
1. Is this exceptoin caused by the xml do not have a namespace xmlns:javaee="http://java.sun.com/xml/ns/javaee
so EMF can not load correct classes?
2. Since I can save without javaee namespace, how to load it back successfully?
Thank you!

Robby,
Given you need access to two namespaces within one instance, and given
you can use xmlns="..." to default only one of the two namespace, you're
going to need prefixes to conform to the schemas. I assume you need
something that actually conforms to the schemas, but your second example
doesn't do that. It makes <description> look like it's in the wrong
namespace.

Robby,
Do you really want to have instances that doesn't conform to your
schema? If that's the case, how about changing the schema (no target
namespace just a single one) to conform to the serialization you want?
In the end, anything you try to do to make this work will be equivalent
to that.
