[rules-users] Drools Flow

[santosh mukherjee]

Hey,
I am able to access the working Memory from an action node. But when I check
for the objects its giving me errors ---

line 2:60 mismatched character '<EOF>' expecting '\n'
Exception in thread "main" java.lang.RuntimeException: unable to execute

All I used is this... inside an action node..

System.out.println(drools.getWorkingMemory().getObjects());

I am just checking as for now, that whatever is written in the documentation
of drools flow actually works or not. This I am doing without any purpose of
a project. If i get to know of each and every functionality, then I may be
able to continue with some project.

And yes, help on how to use the Event node in drools flow is also needed. I
tried passing a map while calling the startProcess from my java class. But
inside the process its not able to access it.

Please any help  is welcome.
