Hi Gabriele,
I am afraid that it currently is not possible to call your own javacode from these templates. Your development project
is not part of the classpath of the template generation. There is specific logic to find template files in your
development project, but not to add javaclasses from your development project. This is quite hard to do. So I am afraid
that you need to implement your logic in xtend.

Is this going to work if I create an Eclipse Plugin with just my "utils" class? This way my class would be in eclipse's (running) classpath, available to be called by Texo when it's running the generator. I'm trying to do this right now, but it still can't find my class.
Otherwise, can you recommend a tutorial on xtend?
For the record, what I'm trying to achieve is modify Texo's behavior when generating initializers on fields.
I need:
1) EEnum fields to be init'd to null, not the enum's first value;
2) EReference to be initialized with a object (i.e. new TYPE()) instead of being set to null, with the added requirment, of course, that if a field's type is an interface, the initialized object must be of a concrete class (for example List -> ArrayList).
I achieved in part 2) by modifying the entity template (I can easily check if a field is a reference), but achiveving 1) and the second part of 2) would be awesome.
Note that I don't want to touch the .ecore file as we generate it from an XSD file.
Regards, and thanks for the quick response.
Gabriele

Hmm, not that won't work with the current version of Texo but I can easily change that. So then you can create a plugin
which adds classes to the classpath of the generator plugin.
I am doing a build right now with this change.

Good to hear that it works, in any case there is now a new build available where you can add your plugin to the
classpath using registerbuddy, add this to the Manifest.mf of the plugin:
Eclipse-RegisterBuddy: org.eclipse.emf.texo.modelgenerator
