Using a deployable JET transformation plug-in

In the Design Pattern Toolkit (DPTK), the PATZIP files can be deployed to a shared directory referenced by the patterns page in the Preferences window. JET has a similar preference page.
To set the JET transform preference:
  1. Click Windows > Preferences.
  2. In the field above the tree list on the left, type jet to filter the choices.

    The EMFT JET Preferences page

  3. Click New and browse to the location containing the JAR files.
When running a JET transformation, JET has the following search order:
  1. Transformations installed in the Eclipse workbench.
  2. Open JET projects in the workspace.
  3. Transformations found in the folders specified in the Addition locations for JET Transformations preference field.
  4. Transformations registered using the org.eclipse.jet.deployedTransforms extension point.
JET transformations can be also deployed in the following ways:
  • Because JET transformations are Eclipse plug-ins, they can be installed directly into an Eclipse configuration if JET is also installed. Typically, this is done by creating an Eclipse feature to contain the plug-in.
  • JET transformations can also be included in another Eclipse plug-in, through the org.eclipse.jet.deployedTransforms extension point. There is a subtle difference between this option and the previous option. With this option, the transformation can be replaced by a copy in the Eclipse workspace. With the previous option, it cannot.
