Hi,
This sounds simple but I can't find any pointers.
I have created a GMF diagram and fired off an action to call my Jet
transformation.
What code do I use to start off Jet.
So far I have always used JET2 using the RUN option setup but never from
code.
Any pointers would be good thanks,
Stu

Since you're using GMF, get a reference to the EMF Resource for your model,
then do
Resource resource = ...;
IStatus status = JET2Platform.runTransformOnObject( "your transfrom id",
resource, aProgressMonitor );
or, if you want to predefine some JET variables, ...
Map variables = new HashMap();
variables.put("varNameWithoutTheDollarSign", varValue);
IStatus status = JET2Platform.runTransformOnObject( "your transfrom id",
resource, variables, aProgressMonitor );
The one difference you may find with this approach, compared to running from
the UI is that the "org.eclipse.jet.resource.*" variables will not be
defined - these are defined as part of loading the model from the Eclipse
workspace - but with this approach, you are passing JET an in-memory model,
so no loading takes place

Thanks for the code.
I feel so close and yet . .
When trying to use the JET2Platform class I get the following error:-
Access restriction: The type JET2Platform is not accessible due to
restriction on required library C:
\apps\wipJEE\eclipse\plugins\org.eclipse.jet_0.7.100.v200702 151055.jar
I have org.eclipse.jet as a dependant plugin.
Thanks for any clues

This error resolved itself.
I've built and rebuilt projects and it seemed to go away in the end.

It must be the little known 'self-correcting-errors' feature of Eclipse ;-)
Actually, I have no idea what's going on there. Here's my approach to weird
Eclipse errors:
1) clean all projects.
2) try closing and opening offending projects. In particular, Java errors
about missing source folders (that aren't missing) seem to resolve this way.
3) try launching Eclipse with a -clean commandline option
