Re: [rules-users] Drools error log msg?
I'll rewrite the rule and give you feedback tomorrow.
"would you be interested in doing some research and see if/how they
impact performance and rule authoring?" - No problem. It would be a
pleasure for me to help.

Re: [rules-users] Drools error log msg?
Hi Davide, thank you for the fast response. I've defined an DebugAgendaEventListener as it's described here: Drools Docu 5.5.0-Final/Section 7.2/HelloWorld example. http://docs.jboss.org/drools/release/5.5.0.Final/drools-expert-docs/html/index.html Where can I find any docu about the config of the DebugAgendaEventListener?

[rules-users] Drools 6 - Trouble with newReaderResource(Reader reader)
Hi list,
try to make my first experiences with Drools 6. For that purpose I've
modified slightly the 'KieFileSystemExample'
(
https://github.com/droolsjbpm/drools/blob/6.0.0.CR3/drools-examples-api/kiefilesystem-example/src/main/java/org/drools/example/api/kiefilesystem/KieFileSystemExample.java
)
as the code below shows. I try to use the newReaderResource(Reader reader)
but when I run maven test I get
the following error:

Any Idea?
Thanks in advance.

Re: [rules-users] Drools 6 Spring JTA Persistence
Hi Alex,
I'm developing a Grails Drools Plugin, too. At the moment I'm working on an
ECA (Event Correlation & Analysis) solution so my current focus is on
expert & fusion. But jBPM is also an important module that I'll need in the
future.
Maybe we can come togehter and create one feature rich grails plugin.
Let me know if you're interested.
Cheers
