JET is a tool for generating one or more files from a model using templates. Templates are a mixture of
text and JET commands (know as tags). The tags extract information from a model, and place it into the expanded
template. JET then writes the expanded template to the Eclipse workspace. A collection of JET templates is called a
transformation. Each transformation is created as a separate JET project.
You can start learning JET by
creating a JET project,
structure of a JET project
and learning the
most common JET tags.
JET transformations extract information from an input model via XPath expressions. You can learn the basics of XPath
In order to test your JET transformation, see
Running JET Transformations
Once completed, you can share your transformation with others. See
