Re: [rules-users] drools5.2 integrate with JMS
Could you please describe use-case a bit? You probably need to look into direction of camel or jbossesb or servicemix, but it depends on what you are trying to achieve.

Re: [rules-users] Who writes your rules? Dev vs. BA
I agree too that it depends on complexity of model and rules itself. Publishing rules to BA may result in BA's learning on how to develop programs (in fact BA is not the right person to write parseDate or some similar function). We tried to tailor Guvnor but result is that we use it only as repository and not as authoring tool (I hope we will tailor DSL and this will be changed..). Amount of rules may be up to 1k in one package - I'm not sure if Guvnor will be user friendly in this case,but using drl you can have 10 files with 100 rules in each (maybe autogenerated from template). Developers don't like Guvnor UI and prefer Eclipse plugin. Also we met an issue with our code repository and Guvnor - so we are building repository import xml for Guvnor from subversion - this helps to manage versions properly (tied to builds). So there are several points to look at. I think if you really need to have BA's writing rules - you must solve this problem, in other case - junit + drl (+flow maybe) is the best fit. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Who-writes-your-rules-Dev-vs-BA-tp2398166p2400829.html Sent from the Drools - User mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Guvnor bulk importer problem
Attaching my version of repository xml generator for Guvnor based on drools
repository api.
RepositoryGenerator scans specified folders and generates packages into
repository then export it as xml into target folder (then unit tests loading
this exported file and perform package testing).

[rules-users] Guvnor bulk importer problem
Hello,
I'm evaluating Guvnor repository import utility.
I found svn location of project
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-guvnor/bulk-importer-util/
also built and generated guvnor-import.xml
But I'm unable to load this xml into guvnor. Tried 5.0 and 5.1.1 versions
Error from Guvnor:
Unable to import into the repository. Consult the server logs for error
messages.
Error from log:
ERROR 16-09 12:38:07,281
(RulesRepository.java:importRulesRepositoryFromStream:9
80) javax.jcr.InvalidSerializedDataException: illegal node name:
{http://ww
w.jcp.org/jcr/sv/1.0}node: Unknown prefix: D: Unknown prefix: D
Can someone point me to working version of bulk importer utility?
Thanks,
Ivan

[rules-users] Event fired in rules not handled properly
Please find attached test case which I use to reproduce problem. To run test
just use "mvn test".
http://drools-java-rules-engine.46999.n3.nabble.com/file/n1405303/event-test%28signalInRules%29.zip
event-test%28signalInRules%29.zip
Issue is that event fired in rules using signalEvent doesn't allow to fire
rules again.
So the issue is:
In flow:
drools.getWorkingMemory().setFocus("create-fault-event");
drools.getWorkingMemory().fireAllRules();
This prints output.
In rule:
drools.getKnowledgeRuntime().signalEvent("LocalEvent", null);
In flow:
drools.getWorkingMemory().setFocus("create-fault-event");
drools.getWorkingMemory().fireAllRules();
No output - rules not fired. Not sure why

Ivan
