hi,
I develop a multi tier appication. The server contain the compare service
and the client should view the reponse. In the server creation of the
MatchModel and the DiffModel work success. But the DiffModel can't display
in the compare view. When I use the default compare plug in and save the
result, it show different as the DiffModel. E.g. it contains both model
the DiffModel and the MatchModel. I try to use the MergeService and it
doesn't work.
some code:

Map options = new HashMap();
MatchModel match = new EcoreMatchEngine().resourceMatch(resourceLeft,
resourceRight, options);
Resource resourceOutputMatch = resourceSet.createResource(URI
.createFileURI("c:/temp/match1.xmi"));
resourceOutputMatch.getContents().add(match);
resourceOutputMatch.save(null);

DiffModel diffModel = new EcoreDiffEngine().doDiff(match);
Resource resourceOutputDiff = resourceSet.createResource(URI
.createFileURI(locateProject+"/temp/diff1.xmi"));
resourceOutputDiff.getContents().add(diffModel);
resourceOutputDiff.save(null);

ModelUtils.save(diffModel, locateProject+"test.emfdiff");

How can I create a reponse.emfdiff which show like the file form the
compare plug in?

thanks

I forget to say that the client is a eclipse plug in and can show emfdiff
files from the compare plug in

Hi Thomas,

Sorry, I've been out of the office and couldn't check the newsgroup for
a while.

You should take a look at the
org.eclipse.emf.compare.examples.standalone example to see the necessary
code to compare two models and save the result in a readable emfdiff.
That said, the code would look something like :

----------8<----------
Map options = new HashMap();
// Matching
MatchModel match = MatchService.doMatch(resourceLeft, resourceRight,
options);
// Differencing
DiffModel diff = DiffService.doDiff(match);

// Create result instance
ComparisonResourceSnapshot snapshot =
DiffFactory.eINSTANCE.createComparisonResourceSnapshot();
snapshot.setDate(Calendar.getInstance().getTime());
snapshot.setMatch(match);
snapshot.setDiff(diff);

// Save result
ModelUtils.save(snapshot, "result.emfdiff");
---------->8----------
