Hi Justin,
I am really struggling to generate the binding. I am trying to generate the
model using eclipse emf plugin and below are my errors. Are there any good
tutorial and examples on how to generate the models using emf from ground up?
Are there any hacks or tips to get around some of the limitations of the emf
plugins eg, hacking the schema files to get the model to generate?
What are the typical scenario in the schema you have to hack that doesn't
comply to the emf model?
If it's not too much work, is it possible for you to generate a binding for
sosGetObservation.xsd so we can reference it as example.

A while back i also put together some docs to help with generating emf models.

Hi Justin and Andrea,
My public repo is https://github.com/victortey/geotool.git
Looks like I have done it the wrong way, I was following
http://docs.geotools.org/latest/userguide/library/xml/internal/tutorial.html
and used jaxb as documented.
Perhaps I should be using EMF as Andrea have done. Is
net.opengis.cat.csw20.Csw20Factory auto generated? If yes, how is it done?
Were you following any documentation Andrea?
Hmm... I don't think I was, but here is some steps from memory:
- install emf and xsd extensions in eclipse
- copy the xsd schemas in the module that will contain the model
- create the first emf model by having it read the xsd
- generate the code
- throw away the impl and modify the generated interfaces as needed
- reload the EMF model, regenerate
- kill the util package just generated, it's not needed
- often that required me to do a "mvn eclipse:eclipse -pl myModule -am" to have
the eclipse project compile again
- iterate over it until you're satistified with package names, return types and
the model in general
Cheers
Andrea
