Guvnor pojo & InitialConext
by gombasp
Hello,
i tried to create a pojo and load it to Guvnor which would call an EJB on
the same Jboss AS 7.1.
Below code works in another app without problem.
public class Calculation implements IFCalculation {
IFRemoteCalculation remoteCalculation;
public Calculation() {
final String jndiName =
"java:global/remoteejb/CalculationBean!com.gp.IFRemoteCalculation";
try {
Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jboss.as.naming.InitialContextFactory");
env.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");
env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
Context ic = new InitialContext(env);
System.out.println("about to look up jndi name " + jndiName);
Object obj = ic.lookup(jndiName);
System.out.println("lookup returned " + obj);
remoteCalculation = (IFRemoteCalculation) obj;
} catch (NamingException e) {
System.out.println("Nem talatam meg a calculation beant! " + e);
}
}
public void add(String s, int faktor) {
remoteCalculation.add(s, faktor);
}
public String getItems() {
return remoteCalculation.getItems();
}
public void setItems() {
remoteCalculation.setItems();
}
}
When i load this as a POJO and try to use it in a Guvnor test scenario with
my rules i get following error:
12:47:17,673 ERROR [org.drools.guvnor.server.RepositoryAssetService]
(http--127.0.0.1-8080-5) Unable to run the scenario.: [Error: could not

It seems it is not possible to get InitialContext in a pojo uploaded to
Guvnor - or is there any way?

Not sure that I did it quite right...
by stephen.masters＠me.com
It seems that Guvnor bug 1507 was resolved as not reproducible. I came across it this morning and have attached a repo extract that demonstrates it.
However, I'm not able to re-open it.
Is someone else able to re-open it? Or would you prefer it if I were to do raise a new bug?
Thanks,
Steve

Re: [rules-users] Loop Drools on Multi Element
by FrankVhh
Hi,
See forall element in Drools manual:
5.8.3.6.1. Conditional Element forall
It does exactly what you describe. For the record, you may want to insert
all your line items separately to working memory.
Kind regards,
Frank

Session persistence
by Alberto R. Galdo
Hi,
We are using Drools Expert, Fusion, Flow, etc... to build a complex
event processing system and one of our main constraints is to be fault
tolerant. As such, we are using an StatefulKnowledgeSession and our system
involves processes, sets of rules, events, accumulators, ... . What we need
is to be able to reconstruct a KnowledgeSession in a given state and all
our changes in the knowledgesession need to be persisted at the very moment
a change is detected.
The documentation is sparse in this point (
http://docs.jboss.org/drools/release/5.4.0.Beta2/drools-expert-docs/html/...)
and what we've seen so far is that our rules are persisted but no
traces
of facts or events ... This would be unaceptable for our product. We need
to be able to stop our service at any time and restore the knowledge
session at any time as it was at the moment of the previous stop.
We have previous experience with JBPM 3 using a persistent storage to be
fault tolerant and it works like a charm, we can see our processes,
process instances, timers, etc... .
Can we get a *full* KnowledgeSession persistence service for Drools?

Guvnor - verify that external RDBMS is being used to store rules
by Kevin Kelleher
Hi,
I configured an external RDBMS (Oracle) as the data store for Guvnor ( on
tomcat 6.0.35) - new repository.xml etc.
Thinks look good .. guvnor launched ok ... entered & validated rules etc ...
Now I want to verify that the rules are stored on the db. ( VERSIONING_*
files etc) as opposed to the default flat files under the tomcat install
dir.
Basically I'm not sure of the best way to do this. The db tables contain
blobs so wont "see" anything there!
Using Guvnor, I edited a test. This updated data in the datastore directory
(C:\apache-tomcat-6.0.35\bin\repository\repository\datastore). Is this
correct behaviour?
If the external DB is used, on tomcat startup, is a "copy" of everything
sent to bin/repository?
I deleted the repository dir under tomcat bin & restarted tomcat. I hoped
that the repository would be rebuilt from the db tables data but this did
not happen.
So can anyone advise?
thanks in advance,
Kevin

Drools : Guvnor issue on tomcat when attempting to use Oracle DB as rule store
by Kevin Kelleher
Hi,
First time post on drools ...
I installed Guvnor 5.3.0 on tomcat 6.0.35. When I used the default
(Jackrabbit) datastore all worked fine.
I next went about trying to change guvnor to use an external RDBMS (Oracle
10g) . I generated a new repository.xml . As per reference manual I used the
Repository Configuration Manager to generate a new repository.xml file.
However on startup with new repository.xml file, I get the following errors
( console, localhost & catalina).
Can anyone shed some light ?
thanks in advance,
Kevin

Does Drools work with Set datatype?
by aitchnyu
I wanted faster (and cleaner) code for intersections and membership checks in
my Drools Planner 5.4 program, so (AFAIK) Set datatype can do it faster.
Can Drools work equally well with Set as with List datatype? I want to use
the `contains` and `memberOf` operations, but I dont care for index access
(set[n])
*Background*: I am developing a timetabling application in Drools Planner.
Each teacher has a list (set!) of periods he may teach. I want to find
intersecting periods between all teachers; so that I can create swap moves.
Drools now has to handle Set datatype instead of List.
