When opening an XMI file (EMF model) inside the Eclipse Modeling IDE you may sometimes encounter the following error:
org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'http://www.abispulsa.com/model/1.0' not found. (platform:/resource/com.abispulsa.model/src/model/Catalog.xmi, 2, 126)at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.handleDemandLoadException(ResourceSetImpl.java:315)

at org.eclipse.emf.ecore.presentation.EcoreEditor.createPages(EcoreEditor.java:1147)
... When this happens in your application, you can register the package to fix it. However in this case the error happens when you want to edit an XMI file (EMF model) inside the Eclipse IDE. To fix it open the file using the plain XML Editor, and change the line : <abispulsa:Catalog xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:abispulsa="http://www.abispulsa.com/model/1.0"> to point to the metamodel's location using xsi:schemaLocation : <abispulsa:Catalog xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:abispulsa="http://www.abispulsa.com/model/1.0" xsi:schemaLocation="http://www.abispulsa.com/model/1.0 abispulsa.ecore"> Now you can open the file in the EMF Editor successfully.
I have exactly the situation you describe here, but happen to be unable to point to an matching .ecore file:
ReplyDeleteIn Rational Software Architect I created an Data model based on Oracle specifics. The resulting model, among other extensions, uses
xmlns:SQLSchema="http:///org/eclipse/datatools/modelbase/sql/schema.ecore"
Having looked into all .jar-Files of the installation I was unable to find a matching File. Instead I found .class-Files in org.eclipse.datatools.modelbase.sql_1.0.900.v20091201_1500.jar that seem to represent the ecore-Metamodel in Java. Is it possible to convert such classes back to an .ecore-Metamodel or is there another option to make the editor understand that a metamodel representation is available?
Satchel understood that the great white players such as Joe DiMaggio for example, received treatment from others that cambridge satchel would help propel their star status and legendary accomplishments. He knew if he was going to ensure his own legacy, he would need to do that self promotion himself. In a way, it's as if Satchel Paige understood cambridge satchel company in this early era the importance of having a personal brand. He even contributed to discrepancies about his age in order to make his accomplishments more extraordinary. We hear that one of the greatest mysteries of the 30's and 40's was the true age of messi jersey!
