Deploying pre-compiled rules files with maven?
by Scott Thibault
I thought when you used the maven plugin that the rules files were compiled
into a binary form so that you could deploy with a minimal set of
dependencies. It's not working for me though. This is my pom.xml file:
<?xml version="1.0" encoding="UTF-8"?>

I build with the mvn package command. The resulting jar file isn't any
different then when not using the plugin. When I try to execute the code I
get the error:
The Eclipse JDT Core jar is not in the classpath
Any suggestions?

Simple ruleflow and java conditionExpression example
by mattmadhavan
Hello,
I have the following requirements.
I have 3 stages of rule-flow group execution.
1. Set of rules to evaluate validation (ruleflow-group "Validation Group")
2. Set of rules to evaluate eligibility (ruleflow-group "Eligibility Group")
3. Set of rules to compute Cancer Measures (ruleflow-group "MeasureCompute
Group");
Validation group will collect all the Validation errors to be saved. After
this group is executed I want to write a* Java condition* to see if any
validation errors present. If they are exit. If not continue to
ruleflow-group Eligibility. Test again after the rules are fired using a
java condition. And so on.
<http://drools.46999.n3.nabble.com/file/n4028039/ruleflow.png>
Can some one please provide me a sample? I am not too keen on too much JBPM
stuff now - Just a simple sample will suffice!
I thank you in advance!
Thanks
Matt

6.0.1.F Guided Rule makes all argument types strings
by SrjTx
I have a global class foo with method bar(int x, int y, string s);
I added it to a globals file as alias x.
In a then in an rdrl, I can select call a method on x, so I choose
bar. I get 3 text boxes
int[ ]
int[ ]
string[ ]
And I fill in
int[3 ]
int[8 ]
string[Hi ]
The resulting source is x.bar("3", "8", "Hi") - which fails validation
because the first two are supposed to be ints. Do you enter ints
differently? Or, is this a bug?
Also note that a space is always a;ready in the text boxes so you have to
delete it first. If you just start typeing hi, you will get the value " Hi"

Guvnor JCR repository
by Demian Calcaprina
Hi Guys,
I am using Guvnor 5.5. For moving packages between environments, I am doing
an export, and then import in the new package. I have a lof of assets in
each package. I am using the DB storage for the jcr repository.
After some months, the DB has grown a LOT! (like 3.5GB).
Is there a way regularly clean the JCR history, or maybe disable JCR
history as we are not using it at all?
These are the steps I did to remove the history and seems to work fine.
Does is seem safe? Is there a better way?
1. Export the entire repository via guvor.
2. Delete all the packages.
3. Stop tomact
4. "truncate" the following guvnor tables:
a. Pm_ws_default_binval
b. Pm_ws_default_bundel
c. Versioning_pm_binval
d. Versioning_pm_bundle
5. Restated tomcat
6. Import what I exported on step #1
Thanks!

[Optaplanner] provisioning / scalability
by Mats Norén
Hi,
I have a use case where multiple users need to run multiple simultaneous
solvers.
Is there a best practice in scaling out Optaplanner for multitenancy?
Just to be clear I'm not interested in scaling out a single optimization
run but instead multiple solvers.
So I'm looking for pros and cons for:
- multiple solvers in the same JVM
- multiple JVM:s on a single machine (with multiple solvers)
- multiple machine setup
- virtual machine vs lxc (Docker) vs bare metal
I'm also interested in provisioning of rules etc
Regards,
Mats

How to add entity classes to Workbench?
by John Manko
I downloaded and configured Workbench (Guvnor), and I'd like to add my
entity classes to it in order to create rules to manipulate their data. I
don't see an JAR import function. Is this possible?
