I am creating a project based on the flow example ( I thought that a
simple icon based programming language for beginners was interesting) so
to learn more I created a plugin project that was a copy of the
flowEditor example but in my own package
(ntu.comp.programming.introduction).
Within this the layout is exactly as flowEditor except that I prefixed
the actions,dnd,model,ui package classes with ProgrammingIntroduction so
for example class ProgrammingIntroductionActivity in
ntu.comp.programming.introduction etc.
I have created a features project and a site update project.
Everything compiles and builds ok and I can successfully update a test
version of eclipse 3.1 with my plugin.
However when I try to create an example or open a file in a view I get
an error message that my plugin was unable to load the required class.
For example was unable to load class
ntu.comp.programming.introduction.ui.ProgrammingIntroduction CreationWizard
This is also the case when I try to run the plugin in the runtime workbench.
I have made an beginners error somewhere but dont know where. Can anyone
help? I inspected the jar file in the plugin area and the classes appear
to be there.
Plugin.xml is
<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>
<plugin
id="ntu.comp.programming.introduction"

Was there a stack trace in the error log?
That you're using a jar file tells me you're not setting up the project
right. There are a number of things that could have gone wrong. I'm not an
expert on this subject, but here's what you should try to setup your
plug-in.
1) Using Import external plug-ins and fragments dialog, import the flow
examples plug-in in your workbench with source folder (no linked content).
2) Make the necessary changes to the project (renaming the project, classes,
packages, plug-in, updating plug-in.xml etc.).
3) Launch the runtime workbench. The runtime workbench should have both
your plug-in (from the workspace) as well as the flow example plugin (which
is still in the plug-ins directory of the eclipse installation).

Pratik,
Thanks for the advice. I dont know what was wrong with the code so I
made a copy of the flow example and re-named the packages. That works ok.
