All,
Thanks for helping.
I have generated EMF from XSD before and all went well. This time,
however, it generates without but won't run. I don't understand. I will
say that this a very complex schema, w3c compliant, but complex
nevertheless.
It generates without error and compiles without error.
The generator created a file called xhtml.ecore but apparently cannot find
it at runtime.
Where must xhtml.ecore be to be found?
The generator also created a file called mif.ecore. Both *.ecore files
were placed in a folder called model. But the generator placed a copy of
mif.ecore in one of the generated packages with the source code. I tried
placing a copy of xhtml.ecore in the same place but to no avail.
I have also tried placing xhtml.ecore on the runtime classpath.
The code line that provokes the error is:
MifPackageImpl theMifPackage =
(MifPackageImpl)(EPackage.Registry.INSTANCE.getEPackage(eNS_ URI)
instanceof MifPackageImpl ?
EPackage.Registry.INSTANCE.getEPackage(eNS_URI) : new MifPackageImpl());
The complaint about the missing xhtml.ecore is near the end of the trace.
The output trace is:

When a model is really large, the importer sets the GenPackage's

false, but likely you'll generate methods that are beyond Java's limit.
When this property is true, it should cause a *.ecore to be generated in
the same folder as the generated package. So the source folder
containing XhtmlPackageImpl should contain the xhmtl.ecore as well after
a successful generation. Did generation complete successfully? I.e.,
there are no errors in the Error Log view. Of course during the build
step, this *.ecore file should be copied to the bin folder so that it's
available at runtime. If the *.ecore is there in the source, check that
it's being copied to the bin folder...

Geoffry,
When a model is really large, the importer sets the GenPackage's
Initialize by Loading property to true; you could try setting it to
false, but likely you'll generate methods that are beyond Java's limit.
When this property is true, it should cause a *.ecore to be generated in
the same folder as the generated package. So the source folder
containing XhtmlPackageImpl should contain the xhmtl.ecore as well after
a successful generation. Did generation complete successfully? I.e.,
there are no errors in the Error Log view. Of course during the build
step, this *.ecore file should be copied to the bin folder so that it's
available at runtime. If the *.ecore is there in the source, check that
it's being copied to the bin folder...
