Problem with DroolsFlow transaction
by HMandic
I have a problem with transaction manager in drools flow (at least I think
so).
I'm running an EJB3 application in Jboss AS 5.1.0GA with Postgres 8.4.4 as
database. I use one schema for my data and another for drools data. The
application itself is also split in two projects, one for my utility classes
that interact with drools and the other for my application that uses those
utility classes.
I'm using the same datasource and transaction type is JTA.
I have an object that holds a reference to processID from drools flow as one
of its fields. When I invoke my method to create that object (in a stateless
session bean), a transaction is opened and it lasts until the end of said
method. But somewhere inside that method I need to invoke
ksession.startProcess(processName, params) and then I get this:
java.lang.IllegalStateException: Wrong tx on thread: expected
TransactionImple < ac, BasicAction: -3f57ffd6:dfb:4c878d37:7e status:
ActionStatus.ABORTED >, actual null
at org.jboss.aspects.tx.TxPolicy.endTransaction(TxPolicy.java:157)

.

.
Does that mean that I need to run the drools part in a separate thread?
I'm clueless...

Error opening dslr in Eclipse on Mac
by Steven Williams
Hi,
I am running Eclipse Helios on Mac OS X 10.6.7 with the Drools 5.1.1 plugin
and cannot open DSLR files with the error below. This error also occurs if I
create a new Drools project, create a new rule resource and select the Use a
DSL checkbox. DRL files open fine.
Could not open the editor: 1

Regression 5.1->5.2 with conflicting ClassNames
by Swindells, Thomas
I'm in the progress of updating from Drools 5.1 to 5.2 in the hope of solving problems we are having with intermittent mysteriously missing activations.
I've found a regression with the compiler which I don't know whether anybody else has noticed before.
In our application we've got two Content classes in different packages, and unfortunately one of our rule files has to reason over both of them.
In drools 5.1 this was fine, we imported one of them and then used the fully qualified name for the other.
I'm just upgrading to 5.2.0-Final and this no longer works. When resolving the unqualified class name drools/mvel(?) was choosing the package that we hadn't imported!
This obviously then gave us loads of misleading error messages about not being able to find fields.
Fully quallifiying all references to both classes fixed the issue but something obviously isn't behaving properly.
Thomas

Guvnor5.1.1 resource local cache
by DroolersEye
Hi,
I am trying to cache the remote guvnor resource locally for guvnor down time
availability to rules engine, I am confusing with two system properties...
1) drools.resource.urlcache
2) localCache
which one is applicable? guvnor documentation points to
"drools.resource.urlcache" than what is the use of localCache?
KnowledgeAgentConfiguration aconf =
KnowledgeAgentFactory.newKnowledgeAgentConfiguration();
aconf.setProperty("drools.resource.urlcache", "/local/dir/path");
KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("test
agent", null, aconf);
is anything wrong in the above code?
when I run I dont see any locally cached resource in referenced folder,
please help me to clear?
Thanks lot....

with kind regards,

NPE on fact insertion if rule has sliding window
by John
Hello,
I've been messing with this for days now and can't get to the bottom of
this. I'm using drools 5.2.0 Final and setting up my KnowledgeBase with a
KnowledgeAgent which is pulling a package from guvnor (also 5.2.0 Final). I
do NOT get this error if I use a KnowledgeBuilder and add the exact same drl
file as a resource.
If the DRL in guvnor has a rule that uses a sliding window, i get an NPE
when trying to insert an object and the following stack trace:
java.lang.NullPointerException
at

Here is the DRL:
1. | package drools
2. | import simple.SimpleType
3. |
4. |
5. |
6. |
7. |
8. |
9. | import simple.SimpleType;
10. |
11. | declare SimpleType
12. | @role(event)
13. | end
14. |
15. | rule "timer"
16. | timer (cron:5/5 * * * * ?)
17. | when
18. | $newest : Number()
19. | from accumulate( SimpleType ($num : number) over
window:time(5s),
20. | max($num) )
21. | $st : SimpleType( number == $newest.intValue )
22. | then
23. | System.out.println("SimpleType: " + $st.number);
24. | end
(note: the first import of simple.SimpleType comes from the package
configuration in guvnor, the second is in the drl file itself. the file will
not validate without the import explicitly listed there, saying the type is
not declared as an event...)
Here is the Java code:
ResourceChangeScannerConfiguration sconf = ResourceFactory
.getResourceChangeScannerService()
.newResourceChangeScannerConfiguration();
sconf.setProperty("drools.resource.scanner.interval", "20");
ResourceFactory.getResourceChangeScannerService().configure(sconf);
KnowledgeBaseConfiguration config = KnowledgeBaseFactory
.newKnowledgeBaseConfiguration();
config.setOption(EventProcessingOption.STREAM);
KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory
.newKnowledgeAgentConfiguration();
aconf.setProperty("drools.agent.scanDirectories", "true");
aconf.setProperty("drools.agent.scanResources", "true");
aconf.setProperty("drools.agent.newInstance", "false");
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(config);
KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent(
"drools agent", kbase, aconf);
String urlString =
"http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/droo...";
try {
URL url = new URL(urlString);
UrlResource urlResource = (UrlResource) ResourceFactory
.newUrlResource(url);
urlResource.setBasicAuthentication("enabled");
urlResource.setUsername("John");
urlResource.setPassword("");
kagent.applyChangeSet(urlResource);
} catch (Exception e) {
System.out.println("Caught exception: " + e.getMessage());
e.printStackTrace();
}
ResourceFactory.getResourceChangeNotifierService().start();
ResourceFactory.getResourceChangeScannerService().start();
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
System.out.println("Initialize drools complete");
SimpleType simp = new SimpleType();
simp.setNumber(5);
ksession.insert(simp);
Thanks,
John

Guvnor and Axis2
by Mario Viertel
Hi,
I am using an own web service (Axis2; tomcat 6) to interact with Guvnor.
All drools related jars (drools*, mvel*, knowledge-api) are contained
in the lib folder of service's aar file. Via knowledge-api the service
interacts with the guvnor repository.
Unfortunately this doesn't work. At runtime a ClassNotFoundException has
been thrown. A look into details revealed that the ClassLoader havn't
loaded all jars containing in webservice's lib folder.
Has anybody an idea what's going wrong. I'm not sure if this is an issue
of drools, the axis2 engine or the tomcat engine.
Thanks,
Mario

running Test scenarios in Guvnor 5.2.0.CR1 causes a memory leak
by vadlam
Hi,
running tests scenarios in Guvnor 5.2.0.Cr1 seems to be causing memory leak
eventually.
since the StatefulKnowledgeSession or the related class seems to have
similar kind of leak in 5.2.0.Cr1, could it be that the same issue is
causing the leak within Guvnor as well ?
we tried to upgrade to 5.2.1.final version of Guvnor, but when we tried to
load the assets in the new Guvnor that were previously created in 5.2.0.CR1
and persisted to a database, we are getting the following errors.
ERROR 29-09 08:25:45,234 (LoggingHelper.java:error:69) Service method

Isee that some of the decision table classes have changed as per the
following lines of code ?
//Post 5.2 model
xt.alias( "decision-table52",
GuidedDecisionTable52.class );
