System problems
by paco
I am using Drools 5.4.0, guvnor 5.3.0 and default database.
I imported the rules with XML file (550 KB) in Guvnor. After I can check,
validate and test (with run analysis button) the rules without problems.
Everything works fine.
After when I import ed other rules XML file (30,000 KB), I realized that the
system becomes too slow and obviously I can no longer veifier, validate or
test my rules.
Please suggest

Adding .package files to a KnowledgePackage
by Paul Ryan
So drools will respect files with a .package extension as a place for declared types, functions, etc. when used with these in the class path. How can a import these into a KnowledgePackage/KnowledgeBase so they can get compiled along with stuff when this is not in the class path at startup? My use case is such that these are not in the same space and can't be loaded at startup time in most cases.
Any help is greatly appreciated,

Changing the java compiler level in drools
by balaji.govindarajulu
I want to change the java compiler level to 1.6 but it doesn't seem to work
for me. I am trying to use generics in the consequence part.
Following is my code that I used to change the compiler level.
*Drools Version: 5.2.1 GA
JDK Version : 1.6*
*final Properties properties = new Properties();
properties.setProperty("drools.dialect.java.compiler", "JANINO");
properties.setProperty("drools.dialect.default", "java");
properties.setProperty("drools.compiler.lnglevel", "1.6");
PackageBuilderConfiguration packageBuilderConfiguration =
new PackageBuilderConfiguration(properties,(ClassLoader[]) null);
final KnowledgeBuilder knowledgeBuilder = KnowledgeBuilderFactory
.newKnowledgeBuilder(packageBuilderConfiguration);*
Let me know where I am going wrong.
Thanks for the help.

Cutom Attributes in Drools
by dme1
Hi,
Is there support for Custom Attributes in Drools? What I want to do is add
attributes which determines when rules should be fired as well as attributes
that the rule updates which I can query at a later time.
E.g. Fire rule only for specific regions. So when new rules are
created/added BAs can define if it is applicable to specific regions.
Then the rule could result in a violation that could or could not be
overriden, so I want to add an attribute called override which is set by the
rule, which I can check after all rules are fired. I can use MetaData to
define this, but I need a pre-defined list which BAs can choose from when
creating a new rule.
Any thoughts on how I can implement this would be appreciated.
Thanks,
dme

Re: [rules-users] Data Model Dependencies in Guvnor
by Stephen Masters
I think this is the only option:
Upload the model into the global area, then within each package, you can create a new model and instead of uploading you can "Import from Global".
Although this is duplication rather than dependency, and you need to copy into each of your packages every time the model is updated. :-/
There is a Jira based on a similar request, but it has been unresolved for a good while:
https://issues.jboss.org/browse/GUVNOR-1401

Data Model Dependencies in Guvnor
by dme1
Hi,
I have created 2 projects in Eclipse - the first one is the Base Project
with the Model defined for this as BaseModel.jar. The send one is the
Extension Project which inherits the BaseModel and extends it, this Model is
called ExtendedModel.jar.
In Eclipse I can set the dependency on BaseModel in the Extended Project and
can write rules using the Base and Extended Models.
Now I create 2 packages in Guvnor one to represent the Base Project, the
second to represent the Extended Project. I upload the BaseModel to the
BaseProject and the associated technical rules and this all works well.
In the Extended Package I upload the "BaseModel.jar" successfully, however
when I try to upload the "ExtendedModel.jar" it gives me an Error. The only
way I can resolve my error is to update the ExtendedModel.jar to include all
classes from BaseModel.jar, so it seems like the Guvnor requires all
dependencies to be resolved within the Model jar and cannot reference other
Data Models within the same package.
Is there a way for Guvnor to lookup the other Models for dependencies and
resolve the dependencies? If not what is the recommended approach for
specifying dependent models in Guvnor?
Thanks,
dme
