<p>I need to run JET templates on a EMF model metadata - i.e. the model itself (not data) is input to my JET template.</p>

<p>More practically -  I want generate non java code, based on EMF templates.</p>

<p>How I do it?</p>

<p>Thank you</p>

I'm not sure I get you right, but you can pass your model just like any other object into the JET template (as described in the
JET tutorial
). Also, it makes no difference if you generate Java or any other text with JET. As an additional pointer, you might want to consider using Xpand (part of
openArchitectureWare
) for very comfortable model to text generation (including things like content assist for your model in the template editor).
