Hello!
I tried the exanple of the standalone version of emf compare which you
can find
under:http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.e mf/org.eclipse.emf.compare/examples/org.eclipse.emf.compare. examples.standalone/?root=Modeling_Project
At first he did not know the type ComparisonResourceSnapshot. Because of
this I replaced the type through ModelInputSnapshot. Now the
example shows no errors but if I try to run the application I get
following exception:

Hello laurent!
Thank you very much for this. The merging runs without any problems. :)

Now I tried to start the comparision editor for the emfdiff result.
I added following lines to the ExampleLauncher:
ModelCompareEditorInput input=new ModelCompareEditorInput(snapshot);
CompareUI.openCompareEditor(input);

After I added this and trying to start the application, I got a lot of
NoClassDefFoundError. For example first was missing
org.eclipse.ui.IEditorInput,
then
org.eclipse.core.runtime.IAdaptable
org/osgi/framework/BundleActivator
org/eclipse/core/runtime/preferences/IScopeContext
and so on..

Because of this I think I'm doing something wrong.
Can anybody help me?

Best regards
rene

Hi Rene,

That doesn't really surprise me, EMF Compare can be run standalone, yet
its UI cannot. Our UI is tightly integrated with the Eclipse UI and thus
heavily depends on it. We have neither RCP nor standalone UI for EMF
Compare and if you seek on displaying the compare editor you will have
to do it from within an Eclipse instance (the code you've copy pasted is
what's needed for that).

Hello laurent!
yes I use Eclipse and also try to start the comparisionEditor in
Eclipse. But I get the errors all the same.

Rene,

The problem you had at first tend to prove you are running a "java
application" and not an "Eclipse application". If what you are tryng to
do is simply compare two files and have the comparison result displayed
in Eclipse, you can simply select your two files, right-click them and
select compare with => each other. The EMF Compare FAQ at
http://wiki.eclipse.org/EMF_Compare_FAQ show how to add your extension
to the list of files EMF Compare should take into account.

If you need to programmatically call EMF Compare without displaying its
UI, you can create a Java program such as shown in the standalone
example. On the other hand if you need to programmatically compare two
files and display the result in the Eclipse comparison UI, you need to
create a plugin and have the comparison code within, then have a way to
call the code of your plugin from a runtime Eclipse workbench
(right-click action on the files for example).

If you have never developped Eclipse plugins, I think the
org.eclipse.newcomer newsgroup is your best bet for pointers on
documentation or tutorials.

Laurent Goubet
