Problem pn Start new process
by reza sadeghzadeh
Hi ,
when I want to start a new process instance I got strange error message:
I'm using jboss 5.1GA and mysql
I attached my codes and error message and persistence.xml
Would you please take a look that it?
Really Thanks

When I insert fact to working memery in the rule file, others rule some time can't be fired.
by luke
Hi,
When I insert fact to working memery in the rule file, others rule some time
can't be fired.
I use the drools rule version is 5.3.0.Final
call rule engine in java and loop 100,then has 1-3 times the "second" rule
and "third" rule can't be fired.
rule file:
package com.sample
import com.sample.pojo.Order
import com.sample.pojo.User
import com.sample.pojo.Item
declare ActivityType
orderId : String
name : String
type : String
end
rule "first"
no-loop true
salience 100
when
$user:User()
$order:Order(userId ==
$user.id,server=="server",operator=="operator",gameName=="gameName",createdDt
> "2011-11-01",createdDt < "2011-11-30",points >= 240)
not Order(userId == $user.id,id != $order.id)
then
drools.insert(new ActivityType($order.getId(),"first","S"));
System.out.println("inserted activity type,"+"
orderId="+$order.getId());
end
rule "second"
salience 2
when
$activityType : ActivityType(name == "first",type == "S")
$order:Order(id == $activityType.orderId,points == 240,amount >= 10)
$user:User(id == $order.userId)
then
$user.setItem(new Item("aaa",1));
end
rule "third"
salience 1
when
$activityType : ActivityType(name == "first", type == "S")
$order:Order(points == 240, id == $activityType.orderId)
$user:User(id == $order.userId)
then
$user.setItem(new Item("aaa",1*$order.getQuality()));
end

HowTo: Installing Guvnor (5.3) on GlassFish 3.1
by Welsh, Armand
I am sure it is probably possible, however, I have been unable to figure out what is needed to get Guvnor running on a vanilla install of GlassFish v3.1
I have tried adding various libraries as per other app server install instructions, and I cannot seem to figure out just what is really needed, and what changes need to be made to the app server to get Guvnor deployed to it.
Any help what-so-ever would be greatly appreciated.

Import static or function in rules-flow constraint?
by capn_ed
I am building a version 5.1 (.bpmn file extension) rules-flow diagram using
the Eclipse plugin.
I am writing rules based constraints (as opposed to code constraints), and I
would like to call a static Java method from some of my constraints.
If I was working in a .drl file, and I wanted to call a static method in my
LHS, I could use one of the following, in the import section of the file:
import static my.package.MyClass.SomeStaticFunction
or
import function my.package.MyClass.SomeStaticFunction
If I open a constraint, and open the "Imports editor", I can add imports for
classes. If I add the first import above to this dialog, and save the .bpmn
file, when I open the Imports editor again, I have the following:
import static
and no reference to the function. If I add the second import above in the
same place, when I save and reopen the dialog, the import function line is
completely gone. I can't see any reference to the function in the .bpmn file
opened in a text editor, either.
Is this the expected behavior?
If so, how can I call a static Java method from my constraint? Do I have to
reference the full package path of the method? Can I only do this from a
Java code constraint? The documentation is silent on the topic of importing
a function for rules constraint, although it says the format is the same as
the LHS of a rule in a .drl file.
I'm using Drools version 5.3.0.Final.

Bugs in Drools 5.3.0 break Fusion event processing
by Richard Calmbach
I am making extensive use of the event processing features of the Drools
rule engine. Upgrading from Drools 5.2.0.Final to Drools 5.3.0.Final broke
47 of my unit tests and also broke my functional tests. There seem to be
multiple changes in Drools 5.3.0 that cause incorrect behavior and/or break
backward compatibility. Here are the results of my investigation so far.
Issue F1:
While tracking down the failures of my unit tests, I experimented with the
Broker example, and while probably not finding the root cause of the broken
unit tests, I nonetheless came across what clearly seems to be incorrect
behavior in the DefaultTimerJobInstance.call() method. The bug only reveals
itself after all input has been processed, so it is masked by the fact that
running the Broker demo through the entire sequence in stocktickstream.dat
(1100 lines) takes a long time. In order to reveal the problem more
quickly, run the demo with only the first 14 lines in stocktickstream.dat.
Do so for both the 5.2.0 Broker demo (against Drools 5.2.0) and the 5.3.0
Broker demo (against Drools 5.3.0). The Broker example code in both
versions is identical, so only the Drools-internal code changes matter.
When running the 5.2.0 Broker demo to the end, you get one
java.text.ParseException (given the structure of the example code, that's
expected, albeit not elegant, and not the focus of our investigation). In
particular, no matter how many lines stocktickstream.dat contains, you
always get exactly one ParseException at the end.
Contrast this with running the 5.3.0 Broker demo: At the end you get N
occurrences of java.text.ParseException, where N is the number of lines in
stocktickstream.dat. So for 14 lines you get 14 occurrences of
ParseException. Looking at two specific methods shows us why:
Method
org.drools.examples.broker.events.EventFeeder.FeedJob.execute(JobContext):
public void execute(JobContext context) {
this.sink.receive( ((FeedContext) context).event );
if ( this.source.hasNext() ) {
((FeedContext) context).setEvent( this.source.getNext() );
this.trigger.setNextFireTime( ((FeedContext)
context).getEvent().getDate() );
clock.scheduleJob( this,
context,
trigger );
}
}
Note in particular how this method already takes care of scheduling the
next job execution by updating the next fire time of the job's existing
FeedTrigger instance. Unfortunately, in Drools 5.3.0,
DefaultTimerJobInstance.call() does a duplicate scheduling of the same job:
Method org.drools.time.impl.DefaultTimerJobInstance.call():
public Void call() throws Exception {
this.trigger.nextFireTime(); // need to pop
if ( handle.isCancel() ) {
return null;
}
this.job.execute( this.ctx );
if ( handle.isCancel() ) {
return null;
}
// our triggers allow for flexible rescheduling
Date date = this.trigger.hasNextFireTime();
if ( date != null ) {
scheduler.internalSchedule( this );
}
return null;
}
So, every job is duplicated and that's why there are 2*N calls to
org.drools.examples.broker.events.StockTickPersister.load() instead of N.
I think the rescheduling inside DefaultTimerJobInstance.call() is
incorrect. For one, it breaks backward compatibility, and it is unexpected.
The job should be in charge of deciding whether there is another job to
schedule or what to do. Implicitly scheduling the next job just by updating
the trigger time is a little too much magic.
Issue F2:
This is the bug that causes my unit tests to fail. I have not pinpointed
the root cause, but it seems to have to do with the event scheduling Drools
does as part of its job execution mechanism. Its symptom is a
NullPointerException during insertion of an event. What makes it so tricky
is that with the out-of-the-box configuration, Drools catches such
exceptions in org.drools.time.impl.PseudoClockScheduler.runCallBacks() and
passes them to the aptly named "DoNothingSystemEventListener", which
literally does nothing, not so much as logging (the methods are empty). So
you don't actually know that the event insertion failed, you only wonder
why your mock WorkingMemoryEventListener is telling you that your
expectations are not met. The stack trace (as copied from the Eclipse Debug
view, hence the unusual formatting) inside Drools is:
Date.getMillisOf(Date) line: 939
Date.compareTo(Date) line: 959
DefaultTimerJobInstance.compareTo(DefaultTimerJobInstance) line: 38
DefaultTimerJobInstance.compareTo(Object) line: 13
PriorityQueue<E>.siftUpComparable(int, E) line: 582
PriorityQueue<E>.siftUp(int, E) line: 574
PriorityQueue<E>.offer(E) line: 274
PriorityQueue<E>.add(E) line: 251
PseudoClockScheduler.internalSchedule(TimerJobInstance) line: 136
PseudoClockScheduler.scheduleJob(Job, JobContext, Trigger) line: 126
ObjectTypeNode.assertObject(InternalFactHandle, PropagationContext,
InternalWorkingMemory) line: 230
EntryPointNode.assertObject(InternalFactHandle, PropagationContext,
ObjectTypeConf, InternalWorkingMemory) line: 244
NamedEntryPoint.insert(InternalFactHandle, Object, Rule, Activation,
ObjectTypeConf) line: 330
NamedEntryPoint.insert(Object, boolean, boolean, Rule, Activation) line: 291
NamedEntryPoint.insert(Object) line: 116
NamedEntryPoint.insert(Object) line: 48
<my code calling into Drools>
Here is method
org.drools.time.impl.DefaultTimerJobInstance.compareTo(DefaultTimerJobInstance):
public int compareTo(DefaultTimerJobInstance o) {
return this.trigger.hasNextFireTime().compareTo(
o.getTrigger().hasNextFireTime() );
}
Essentially, this method calls java.util.Date.compareTo(Date) with a null
argument, which, as documented, causes a NullPointerException. Sometimes,
this.trigger.hasNextFireTime() already returns null, and then the NPE gets
thrown in DefaultTimerJobInstance.compareTo() itself.
I've seen different stack traces leading to this NPE, so this must be
affecting scheduling and job execution quite broadly.
Issue F3:
It is debatable whether this is a bug, but it is a backward-compatibility
breaking change. Previously, when scheduling a job with
org.drools.time.TimerService.scheduleJob(Job job, JobContext ctx, Trigger
trigger) (for both real-time and pseudo clock), you could pass a null
JobContext (say, because you didn't need one), and it would work. However,
in Drools 5.3.0, this causes a NullPointerException at:
org.drools.time.impl.DefaultTimerJobFactoryManager.createTimerJobInstance(Job,
JobContext, Trigger, JobHandle, InternalSchedulerService) line: 25
I realize that if it's not in knowledge-api-<version>.jar, it's not an
official API, but the available interfaces and classes in
org.drools.time.** (as used in the Broker example) are *very* useful for
test harnesses *and* for production code (for implementing dynamic timers,
for instance). So, this is more of a heads-up: If you are suddenly getting
an NPE, this might be the cause.
Please let me know whether I should create JIRA bug reports for issues F1
and F2. Also, I'd be interested to hear whether others have run into issues
with Fusion in Drools 5.3.0.

A little suggestion about the 'ResourceFactory', 'DrlParser' API
by Miles Wen
Would you please provide a method in 'org.drools.io.ResourceFactory' like
this:
public static Resource newReaderResource(InputStream stream, String
encoding);
then I can use this method to load drl files as a stream while explicitly
specify its ecoding?
And in line: 287 of class 'org.drools.compiler.DrlParser':
lexer = new DRLLexer( new ANTLRInputStream( is ) );
no encoding specified as well. The ANTLRInputStream has constructors which
allows you to specify the encoding, otherwise it would figure out the
encoding according to the environment, which is unpredictable some times.
I'm using drools 5.3.0, the newest version. Thosse problems exists for
quite a while during previous versions. I'm fainting to see they are almost
there after upgraded to the new version.

NPE while creating Session using SimpleCredentials
by Praveen
Hi,
I am getting NPE at line 3, I doubt if SimpleCredentials is an issue over
here.
Please provide inputs if someone has faced the same.
try {
Repository repository = configurator.getJCRRepository(
repositoryHomeDirectory );
Credentials credentials = new SimpleCredentials("admin",
"admin".toCharArray());
//line 3 Session session = repository.login(credentials,
"production");
Node node = session.getRootNode();
System.out.println("root node path: " + node.getPath());
} catch (Exception e) {
e.printStackTrace();
}
TIA.
Regards,
Praveen.

Writing complicated rules - consecutive number problem
by LCode
I am trying to write a rather complicated rule via the guided rule editor and
I wonder if it is indeed possible.
The following is a simplified explanation of my scenario:
A 'person' has a numerical property 'age'
In a hypothetical world the following is allowed because the ages of the
people are consecutive:
Person A age = 24
Person B age = 25
Person C age = 26 OK
Person D age = 27
However I would like to write a rule that fires if the ages are not
consecutive, something like this:
Person A age = 24
Person B age = 25
Person C age = 29 NOT OK
Person D age = 27
I am starting with 'From collect all people [p]'.
Any thoughts, comments or similar experiences much apprieciated as I am
pulling my hair out!
Jen
