Hi,
I would like would like to load an XML model with a XML schema which is
defined
below. I am using Eclipse 3.1 and EMF 2.1 (I am not using RSA anymore)
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.com.mydb/db"
targetNamespace="http://www.com.mydb/db">
<xsd:complexType name="tableType">
<xsd:attribute name="name" type="xsd:string" use="required"/>
</xsd:complexType>
<xsd:complexType name="dataBaseType">
<xsd:sequence>
<xsd:element maxOccurs="unbounded" name="table" type="tableType"/>
</xsd:sequence>
<xsd:attribute name="name" type="xsd:string" use="required"/>
</xsd:complexType>
<xsd:element name="dataBase" type="dataBaseType"/>
</xsd:schema>
My XML file looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<dataBase name="db12"/>
So, without defining a targetNamespace in the XML schema it works fine.
But with the mentioned targetNamespace "http://www.com.mydb/db" I get a
PackageNotFoundException which is displayed at the bottom...
I guess this comes from the logical URI of the targetNamespace, which
Parser hasn`t the physical URI for, right?
IŽve read something about a URIConverter, which you can use for mapping
logical URIs tu physical URIs.
So IŽve tried the following Java Code:
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).
put("*", new DbResourceFactoryImpl());
ResourceSet resourceSet = new ResourceSetImpl();
URI uri =
URI.createURI("file:/C:/eclipse/workspace/DbPlugin/samples/load/db.xml ");
URI uri1, uri2;
URIConverter converter = resourceSet.getURIConverter();
Map map = converter.getURIMap();
map.put(uri1 = URI.createURI("http://www.com.mydb/db"),
uri2 =
URI.createURI("platform:/resource/DbPlugin/src/xmlSchema/dbSchema.xsd "));
DbResourceImpl resource = (DbResourceImpl) resourceSet.getResource(uri,
true);
I still get the same exception. What still I need to do?
Thanks in advance.

Enrique,
Have you looked closely at the generated *Example.java in the generated
*.tests plugin? That example provides a working example of what things
you need to register when running standalone.
Note that to conform to your schema your instance should look like:
<?xml version="1.0" encoding="UTF-8"?>
<dataBase xmlns="http://www.com.mydb/db" name="db12"/>
or
<?xml version="1.0" encoding="UTF-8"?>
<prefix:dataBase xmlns:prefix="http://www.com.mydb/db" name="db12"/>
