I have 2 domain models let's say Manager and Employee.I have got the ecore model for this and generated the GMF .I could create these models at runtime choosing from the palette.

My requirement here is ,
At runtime i need to select a particular domain model and the XML (domain instance)for that should be generated.

Eg. When i click on the Manager domain at runtime i need to get the XML (containing the Manager instance) .When i click both manager and employee then i need to get the XML genertaed for both instances including the relationships that is defined between Manager and Employee.

Could any body suggest a solution/approch for this please?

Thanks in advance!

I'm not sure what you mean by "get the XML". You model instance at
runtime will contain all the data you need. They're serialized to and
from XML.

You are right. I mean to say that after entering the values for each of the instances , suppose that i want only the Manager instance (then i would click on that ) and have the XML extracted for Manager instance alone and sent to the downstream systems conforming to another XML Schema.

Thanks!

Often a snippet of XML won't conform to a schema because it won't
correspond to a root element declaration. This XMLResource save option
will be useful:

/**
* Write only the subtree starting at the specified list of EObjects,
* which must be objects contained by the resource.
*/
String OPTION_ROOT_OBJECTS = "ROOT_OBJECTS";

Thankyou very much for pointing out the right approach.

I have auto generated the ResourceFactoryImplementation.java and ResourceImpl.java files .

I am using the following code snippet to serialize the model instance.

ProductOfferingVersion productOfferingVersion = theUkbsstoolFactory.eInstance.createProductOfferingVersion() ;
ResourceSet resourceSet = new ResourceSetImpl();
URI fileURI =
URI.createURI("./ukbss.xml");
Resource resource = resourceSet.getResource(fileURI, true);
resource.getContents.add(productOfferingVersison);
resource.save(null);

My question here is , where should i place this piece of code so that my instances get saved ?

Thanks!
