[rules-users] Effective Dating of Rules
Is there a way to effective date a rule through a program? Requirement: without using the Guvnor UI to write the rules, trying to upload a .drl file using REST APIs which already has rules specified "without" the date-effective/date-expire attributes. Is there a way to maintain versions that could be used by effective dating the entire package itself? Or in general, how do we effective date the rules in Guvnor without using date-effective attributes for rules and create a knowledgebase from the package based on the current date?

[rules-users] Getting POJO through rest from Guvnor
Hi, Uploaded a POJO to Guvnor and I was able to build the package successfully. I can download the MODEL jar from http://localhost:8080/guvnor-5.5.0.Final-tomcat-6.0/org.drools.guvnor.Guvnor/package/packName/LATEST/MODEL through the web browser. Wished to know how can I download the jar in my JAVA program in order to create the KnowledgeBase.

[rules-users] Upgrade from drools 5.4 to 6.0.0-Beta3 - Legacy API Adapter JAR
Hi,
There is not enough documentation on drools v6.0.0-Beta3, but this is what
I'm trying to do.
Our system was designed with 5.3 but then we encountered the issue with
synchronization (https://issues.jboss.org/browse/JBRULES-3283), so we
upgraded to v 5.4.
Things worked fine until we multithreaded the client code due to which we
faced another issue (https://issues.jboss.org/browse/JBRULES-3675)
So finally now, I'm trying to upgrade to 6.0.0-Beta3 since both those issues
should've been fixed with 6.0.0-Alpha1. The problem I'm facing is, I do not
have enough documentation to look at to see how to convert those things. I
went through the slides etc that were posted on the mailing list for the
conferences, but I'm still unable to figure it out correctly..
So, can someone point me to a JUnit or something that I can look at to
figure this thing out?
static {
KieServices ks = KieServices.Factory.get();
KieRepository kr = ks.getRepository();
Resource res = ks.getResources().newFileSystemResource(
"src/main/resources/rules/abc.drl");
KieModule kModule = kr.addKieModule(res);
kc = ks.newKieContainer(kModule.getReleaseId());
}
throws an exception on kr.addKieModule(res) which says Error in opening zip
file.. I assume we are now expecting a jar instead of a plain drl file. Is
there a way to convert this drl into a jar that the 6.0 code can understand
(for compatibility purposes with the existing system)?
Another thought was to make use of the Legacy API Adapter JAR, but I
couldn't find any examples of the same. Can you point me to a code
sample/JUnit that could explain how this works?
Thanks

[rules-users] Upgrading to Drools 6.0 questions (General)
Hi, We are trying to evaluate what it takes to move from drools 5.4 to drools 6.0 There are some questions that I'd appreciate if someone clarifies after I've updated the code to use KieContainer instead of KnowledgeBase and successfully upgraded to drools 6.0.0-Beta3 1. Resolution of the imports: In previous versions (5.3/5.4) we were able to give import abc.def.* which would import all the model classes required by a .drl file, this doesn't seem to be valid anymore. Now we have to give a specific class name in every import statement so the 6.0 compiler is still able to use it. (eg) import abc.def.SomeCalss. Is that a change that was done to the compiler to resolve the imports, or is it just me? 2. Setting null values: Some rule in one of my drl files was of the form - delare SomeDate date : java.util.Date end rule "do something" when . . then insertLogical (new SomeDate(null)); end I'm assuming the compiler is calling the java.util.Date constructor which shouldn't allow you to create a date with null being passed to the constructor. This was ok with the previous versions (upto 5.4) and now throws a NPE in 5.5 and 6.0. I'd think this should actually be throwing an IllegalArgumentException with Date but throws a NPE instead. Is that true? Is the drools compiler now catching that llegalArgumentException and throwing a org.kie.api.runtime.rule.ConsequenceException due to null Date? 3. KieContainerImpl not serialized: >From KnowledgeBase javadoc - Creating the KnowledgeBase can be heavy, where as session creation is very light, so it is recommended that KnowledgeBases be cached where possible to allow for repeated session creation. We could achieve this using the EhCache and caching Knowledgebase objects. We cannot do the same with KieContainer since it throws a SerializationException with KieContainerImpl is not Serializable. So seems like we cannot cache these KieCaontainer objects? Or is there some other way to do that? 4. Release date for 6.0-Final: What does the roadmap look like for the 6.0-Final? Thanks. -- View this message in context: http://drools.46999.n3.nabble.com/Upgrading-to-Drools-6-0-questions-General-tp4024812.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
