Hello everyone,
I yet again have another problem with EMF. We are no so far that we want to save the current model in a XMI File so we can load the current settings the next time the application starts again.
I read through this tutorial which describes the necessary steps very precisely:
http://www.vogella.com/tutorials/EclipseEMFPersistence/article.html
I did everything exactly as it was described, but as soon as I press the save button and the method resource.save() is invoked I get a java.net.MalformedURLException: unknown protocol: z
Here is the complete exception stack:
at java.net.URL.<init>(Unknown Source)
at java.net.URL.<init>(Unknown Source)
at java.net.URL.<init>(Unknown Source)
at org.eclipse.emf.ecore.resource.impl.URIHandlerImpl.createOutputStream(URIHandlerImpl.java:110)
at org.eclipse.emf.ecore.resource.impl.ExtensibleURIConverterImpl.createOutputStream(ExtensibleURIConverterImpl.java:349)
at org.eclipse.emf.ecore.resource.impl.ResourceImpl.save(ResourceImpl.java:996)
In the tutorial they say that you will get an exception when you miss to add some objects, but I'm very sure that I added all objects that don't have a "contains relationship". So after trying for more than two hours to solve this problem I thought maybe someone else had a similar problem and can help me out here.
Thanks in advance for your help.
Best regards,
Tom

From that message I would guess you set the resource's URI to something
like "z:\local\path"? If that is the case, you need to create a proper
URI (starting with "file:/") using something like
URI.createFileURI(""z:\\local\\path").
