In this example, the Java EMF Model (JEM) is referenced by its gener-
ated_package , as shown here in its plugin.xml file:
<extension point="org.eclipse.emf.ecore.generated_package">
<package
uri="java.xmi"
class="org.eclipse.jem.java.JavaRefPackage" />
</extension>
RegisterEcoreFile
To explicitly register a metamodel using its .ecore file, use the
RegisterEcoreFile element. In this example, the mindmap.ecore file is ref-
erenced from another project in the workspace:
< bean class="org.eclipse.emf.mwe.utils.StandaloneSetup">
< platformUri value="../" />
< RegisterEcoreFile value=
"platform:/resource/org.eclipse.dsl.mindmap/model/mindmap.ecore"/>
</ bean >
Note that it is possible to use any valid URI scheme in the value attribute.
For example, if you want to reference a file within a *.jar file, declare the path
as follows:
< RegisterEcoreFile value="jar:/file:/my.jar!/model/my.ecore"/>
ExtensionMap
If the EMF extension_parser extension-point is to be used to load a model,
you can use the ExtensionMap element, as shown here. Also shown is the con-
tribution from the corresponding model plugin.xml file.
< bean class="org.eclipse.emf.mwe.utils.StandaloneSetup">
< platformUri value="../" />
< ExtensionMap from="gmfgen"
to="org.eclipse.gmf.internal.codegen.util.GMFGenResource$Factory"/>
</ bean >
<extension point="org.eclipse.emf.ecore.extension_parser">
<parser type="gmfgen" class=
"org.eclipse.gmf.internal.codegen.util.GMFGenResource$Factory"/>
</extension>
