Does ecore only supports .xmi models? [message #541972]

Wed, 23 June 2010 08:28

Eclipse User

Hi all,

I have source and target meta models and now I want to input my model as say "buildToBuilder.xml" as

Source Model IN:
           buildToBuilder.xml

and 

Target modle OUT:
      test.xml

Now I am wondering if the buildToBuilder.xml file should be in xmi format? otherwise I am getting errors like

Error loading platform:/resource/WSCDL2SWBPEL/BuildToOrder.xml: org.eclipse.emf.ecore.xmi.ClassNotFoundException: Class 'package' is not found or is abstract. (platform:/resource/WSCDL2SWBPEL/BuildToOrder.xml, 2, 400)

No, you should be able to read pretty much any XML format.

Registering an appropriate factory is often important though.

Hi Hitindeep

Alternatively if you use a schema location to refer to your meta-model,
you may find that reflective/dynamic EMF works for you without needing
to generate Java models.

e.g. in buildToBuilder.xml

<mine:Ccc xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mine="mine" xsi:schemaLocation="mine My.ecore"/>

I tried the ways and some of the other issues appeared.

I derived the metamodels from respective xsd file and I added

Quote:

<mine:Ccc xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mine="mine" xsi:schemaLocation="mine My.ecore"/>

.

When I try to open the xml file using the reflective ecore editor then again same error appeared as:

Quote:

PackageNotFoundException: package with uri "null" not found.
PackageNotFoundException: Class "Package" is not found of is abstract.

Does it make difference if I have Package in wscdl.ecore file and package in xml file?

Like in ecore file I have this.

and in input model I have

Hi

You need to define the namespace for "package", either by perhaps

<cdl:package xmlns:cdl="http://www.w3.org/2005/10/cdl"

or

<package xmlns="http://www.w3.org/2005/10/cdl"
