Hi everyone,
I have followed this tutorial, which says that I can start by defining my interface using Rational Rose or annotated Java:
http://help.eclipse.org/kepler/index.jsp
EMF Developer Guide > Tutorials
Generating an EMF Model
Last updated: June 18, 2007
(sorry, there is no direct link to this help page that I can find).
I went through the "Library" example and it worked OK.
I also found another tutorial from Lars Vogel here:
http://www.vogella.com/articles/EclipseEMF/article.html
This describes using the Juno version rather than Kepler, and he does not mention anything about creating the interface via either Rational Rose or using annotated Java. He also includes screenshots of a "visual editor for creating EMF models", that corresponds to nothing I have seen in Kepler.
I am using Kepler just to keep up with the latest stuff, although I also have Juno installed. I can use either one, whichever is better for this.
When I tried to create my own generators following the general steps using Lars Vogel's approach, I can create a genmodel from the ecore file. When I "generate all" from the genmodel, the 3 projects are created, but when I attempt to "Run as Eclipse Application" from the editor, it shows an error which ultimately traces to inability to locate the "holyCityAudio.com.SpinCAD.Package" (everything before "Package" is the path of my project and location of the "model" folder I am using for this exercise).
I'm sure this all boils down to some obvious setting I am missing, but since the tutorials don't necessarily explain the significance of everything, I am failing to understand the root cause of the problems I am seeing.
In summary, two questions:
1) Is there a way to generate the needed "Interface" using Ecore tools, or is it really needed to use Rational Rose (which costs about $2500) or using annotated Java (which is easy enough)?
2) Any idea what I have done wrong which results in the inability to resolve the "Package"?
Many thanks,
GW

In section "2. Installation" it describes how to install Ecore Tools...

The latest is generally best...

I'm quite confused by this sentence...

No Rational Rose is an old fossil. Can you even buy it anymore? You can
use The Ecore Tools graphical editor, the Sample Ecore Editor,
annotated Java, or Xcore (http://wiki.eclipse.org/Xcore) to create your
models.

I'm confused by what is trying to resolve this. In which file does this
error appear?

Hi Ed,
Looks like I completely missed the install of the "Ecore tools". Thought I already had it installed because the icon for the "Ecore model" and "Ecore diagram" are similar. Unfortunately at home I am using a laptop rather than large dual screens which makes following these tutorials a bit difficult.
Sorry about the dumb question but a different perspective did help break through the most obvious problem!
I will go solve that and then come back if my problems persist.
Thanks,
GW
