Hi Pranav,
why are you embedding an engine instantantiation + participant
registration inside of a process definition ? There are no such
examples in the documentation... Ruote is an interpreter for process
definition, it's not the task of the process definition to instantiate
the engine.
Since you are using ruote-web2, ruote-web2 does the job of running the
ruote engine for you.
If you need to register participants, you can do it under
config/initializers/participants.rb but that will require a restart of
ruote-web2.

In ruote-web2, participants names are automatically mapped to user or
group names. If for example of have a user "alice" and a group
"authors", this process definition :
---8<---
OpenWFE.process_definition :name => 'sample' do
sequence do
alice
authors
end
end
--->8---
Will deliver a workitem to Alice and then to the authors group. You
won't need to register any participant as long as the the user and the
group exist.
Not that for proceeding a workitem in ruote-web2, you simply locate
the workitem under /workitems, click on it, then hit the "proceed"
button.
Best regards,
