[rules-users] Drools Flow: how to get knowledge session ID from WorkItem

[Alan.Gairey at tessella.com]

Chris, Anatoly, Mauricio,

Thanks for your replies. I had implemented a solution similar to that 
suggested by Chris; my work item handlers are defined as Spring beans, so 
as long as they are defined with scope="prototype", the knowledge session 
can be injected into the handler.
I just wondered if there was a "simpler" way of determining the session 
directly from the work item.

Anyway, thanks again for your help,

Alan

Anatoly, if you can share your generic implementation that would be nice.. 
because a lot of people is looking for something like that.
I prefer custom and domain specific implementation, but it seams that a 
lot of people is looking for something generic that can be reused.
I can blog about that generic idea too to spread the word and also mention 
the different situations and the perspective of having decoupled and 
coupled applications to the work items.

@Alan,

   Implementation of WorkItemHandler is a custom ( "your" ) component. 
This
means that this implementation may have anything injected ( set as 
property
or at construction time ).

   Let's say you implement "YourCustomWorkItemHandler" to take a "session
id" at the construction time ( good choice :) ), then to start the process
you would:

               session = create a newStatefulKnowledgeSession()

               session.getWorkItemManager().registerWorkItemHandler(
                               "WorkItemName", new 
YourCustomWorkItemHandler( session.getId() ) );

               session.startProcess( "process-name" );
