I am new to JET and would like to following the tutorial. But I have
question as follow:
Where should I copy the following code?

>We can create an instance of the HelloWorldTemplate template implementation
>class and invoke its generate method like this:

> HelloWorldTemplate helloworld = new HelloWorldTemplate();
> String result = helloworld.generate(null);
> System.out.println(result);

In the template, HelloWorldTemplate, or a new java file? How to run the
generated file? Thanks.
Williams.

Williams,

For any .java file that contains a main() method, you'll be able, from
the editor or on the file itself in the explorer, to invoke "Run
As->Java Application"

Thanks, Ed. I got the following link:
http://www.eclipse.org/articles/Article-JET/jet_tutorial1.ht ml

when I typed jet tutorial 1 in google, which seems obsolete.
Now I know how to do it. Thanks.
W.

I, too, have a question. I cannot follow the tutorial. I do not seem to have
JET installed. I have tons of EMF plugins now, but there is no such thing as
a JET nature or any JET preferences. Where do I fail?

Bye,
Mike

Mike,

Is org.eclipse.emf.codegen installed? That's where JET is located. If
org.eclipse.emf.codegen.ui is installed, then you should be able to add
a jet nature to your Java project.

Yes, both are installed (version *_2.4.0.v200902171115). Still, no JET can
be seen anywhere in Eclipse.

I remember that it did work quite some time ago when I first looked at it.
The tutorial is also a few years old. Did something fundamental change?

Mike

Mike,

It should still work with File->New->Other..->Java Emitter
Templates->Convert Projects to JET Projects... Isn't that available?

No, it was not available. However, I downloaded and installed a fresh
Eclipse and added the two EMF Codegen plugins to it, et voilà, it started
working again.

Eclipse seems to be like Windows used to be, a fresh install from time to
time works wonders. The amount of time I spent hunting for plugin yesterday
is quite sad, but I thank you for confirming that I already had the right
plugins in view.

Bye,
Mike
