Ecore model not properly registered [message #1725048]

I've created a DSL with xtext 0.7

My goal is to parse a string with this dsl model, but i have some problem with the model registration.

When I try this code

URI dummy =URI.createURI("dummy:/example.cblData");
ResourceSet resourceSet = new ResourceSetImpl();
Resource resource = resourceSet.createResource(dummy);
InputStream in = new ByteArrayInputStream(preprocessedCode.getBytes());
try {
	resource.load(in, resourceSet.getLoadOptions());
} catch (IOException e) {
	e.printStackTrace();
}

createResource method always returns null.

When I try this code

URI uriEasyFile = URI.createURI("file://C:/FAST_BP/_work/workspace/pru.cblData");
ResourceSet rs = new ResourceSetImpl();
Resource r = rs.getResource(uriEasyFile, true);

GetResource method thows "Cannot create a resource for 'file://C:/FAST_BP/_work/workspace/pru.cblData'; a registered resource factory is needed"

When I use the "Generic EMF From Editor" the model is opened correctly, but not from my class. Why don't found the Factory if the generic emf editor can open it?.

Thanks in advance.
Jose

You should call New
YourdslStandaloneSetup().createInjectorAnDoEmfRegistration() somewhere. And
the file extension is case sensitive

I'm not sure if the standalone setup already existed in Xtext 0.7. Are you really sure that it is the ancient version 0.7 and not something more up to date? If you use Xtext nowadays, Christian's answer to call the setup class is correct.

Christian you are right, now the code is:

URI dummy =URI.createURI("dummy:/example.cblData");
DataStandaloneSetup.doSetup();
Resource resource = resourceSet.createResource(dummy);
InputStream in = new ByteArrayInputStream(preprocessedCode.getBytes());
try {
	resource.load(in, resourceSet.getLoadOptions());
} catch (IOException e) {
	e.printStackTrace();
}

It run correctly.

Thanks!
