I'm cross posting this to the EMF newsgroup, as JMerger lives within EMF.

Ed, we await your wise response.

The org.eclipse.emf.examples.jet.article2.codege example is updated to
use the non-deprecated merger.

I think the one that uses the AST facade, the default, does work stand
alone because it's JDT dependencies also work stand alone.

Yes, JDT's JDOM doesn't work stand alone.

Yes, I think so. But I seem to recall that the AST-based version did
work stand alone.

Ed,

Thanks for your help, but I can't find what you referenced. I grep'd and googled for: org.eclipse.emf.examples.jet.article2.codegen

I did find a CodeGen class, but it uses the deprecated JMerger, and it deals with JET output, not generated Java sources.

Can you provide a bit more context for me? Where would I find the example you are referencing?

Thanks!

If it's not available as an installable example or as part of the
article (though it's the source for it), then you can get it straight
from CVS:

Ed,

Thanks, I think I found the article:

http://www.eclipse.org/articles/Article-JET2/jet_tutorial2.h tml

This is still based on the deprecated version. But at least now I see how to provide missing pieces that were probably causing the NPE before. I will give it a shot.

If you know for sure that a more recent article exists that documents the newer JMerger please point me to the URL.

Thanks!

I think only the code in CVS was updated to fix the deprecation warnings...
