[rules-users] Using global variable in DRL file

[Michael Anstis]

So, you have multiple CSVBeanAgent's (created from a text file somewhere).
These are stored in a Map created in Java called "globals".

Where do you actually set the global in WorkingMemory: See
http://docs.jboss.org/drools/release/5.4.0.Final/drools-expert-docs/html/ch04.html#d0e4482
.

Furthermore, the Global will be of type Map not CSVBeanAgent, unless you
want a Global for each CSVBeanAgent - but then how do you decide which you
need.

Personally, I'd go back to inserting CSVBeanAgents as Facts and tackle the
Java Heap Space issue... there are definitely things you are not telling us.

With kind regards,

Mike
