You can use portlet context to retrieve portal user login and then use it for
task retrieval
| facesContext.getExternalContext().getRemoteUser()

or
| portletRequest.getRemoteUser()

You should write you own portlet webapp or try to run jbpm-console as a portlet
via some existing jsf portlet bridge.

I propposed you better solution. Because you can simply add comments to the
task or dirrectly to the process and then know for which task the comment was
done.

Oh, i am sorry, you didn't write anything about jbpm-console. But all other
recommendations are still actual. You need to find all process instance tokens
with the method findAllTokens(). Then iterate through tokens and get their
comments with the method token.getComments() and add all comments
Comment is not gone when the task is finished. It is just the jbpm-console
problem which displays only process root token comments or task comments but
doesn't display all comments at the same time.
To display all comments you should to iterate through process tokens and
display comments for all
Surely it is not the JBPM console problem. It is your local system problem,
perhaps you have a virus.

You shouldn't put action command to the tf:saveButton directly because all jbpm
form actions described directly in the j4j:taskForm tag in the JBPM console
application.
To upload files in the task variable map you should to have own tag and use it
inside standard action components commandButton
1. Not sure, but you can use jbpm-enterprise component to avoid synchronization
issues if there are any
2. Jackrabbit is supported by the jbpm. Look on the jbpm documentation and cvs
repository for examples.

It is not so hard to implement. You should know what task is first in process
definition, or use startTask from TaskMgmtDefinition if you have it, i mean
startTask. Then you should search all taskInstances for task with id equal to
startTask id and actor equal to user. As a result you should man

You can use NewProcessInstanceCommand with createStartTask as true, if returned
value will be null then you will know, that process doesn't contain a start
task. Then you can use SignalCommand or some other one to move process from
