Re: [rules-users] Exception using persistence
Robert, what's your application server, or your transaction manager?
I successfully tested with bitronix in my J2SE application, and with the jboss
application server transaction manager.
I don't have any further idea for your problem, but, from my own point of view,
it's not so dirty to bind it to java:comp/UserTransaction, and is probably your
only way to do things without patching the code (as you seem to have seen in
the source code java:comp/UserTransaction is not in a variable so...

For additional information:
JPAKnowledgeService.newStatefulKnowledgeSession uses
org.drools.persistence.session.SingleSessionCommandService
where java:comp/UserTransaction is used (I checked the drools source code).
Looks like there is no way to change this.
I just wonder that I am the only one having this problem.
As I said comp/UserTransaction works, but java:comp/UserTransaction
doesn't, but in the docs java:comp/UserTransaction is used !?!?!?
Cheers, Rob.

It's probably that your transaction manager, for an odd reason,
doesn't bind with the good name; You can do the following workaround:
Final InitialContext initContext = new InitialContext();
initContext.bind(java:comp/UserTransaction,initContext.lookup(comp/
UserTransaction));
And voila, those two jndi name should point to the same object.
I stress the fact that what I've written hasn't been tested.

Hi,
still struggling with this one (see below),
but I did a slide change in the test-code
try {
val env = new java.util.Hashtable[String, String]
env.put(Context.INITIAL_CONTEXT_FACTORY,
bitronix.tm.jndi.BitronixInitialContextFactory)
val ctx = new InitialContext(env)
val ut1 : UserTransaction = (ctx.lookup(
java:comp/UserTransaction)).asInstanceOf[UserTransaction]
} catch {
case ex: Exception = ex.printStackTrace()
}
(Sorry, code is in Scala, but should not be a problem to read it).
Instead of java:comp/UserTransaction (as written in the docs) I
wrote comp/UserTransaction and it works.
But since this is some test-code and I am able to do the look-up as I
want (comp/UserTransaction), as soon as I use
JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env )
I have no influence anymore (its drools-code ;-) and it looks like its
using internally java:comp/UserTransaction.
Is there any way to change this (setting it) ?
Cheers, Rob

Well, I tried this but it does not work.
Checking additionally the BitronixInitialContextFactory API where it
says:
-
Implementation of InitialContextFactory that allows lookup of
transaction manager and registered resources.
The easiest way to use this provider is to create a jndi.properties
file in your classpath with this content:
java.naming.factory.initial=bitronix.tm.jndi.BitronixInitialContextFa
c tory Alternatively, you can create a InitialContext object with an
environment pointing to this class:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
bitronix.tm.jndi.BitronixInitialContextFactory);
Context ctx = new InitialContext(env);
The transaction manager can be looked up at the standard URL
java:comp/UserTransaction while resources can be looked up using
their unique name as set in ResourceBean.getUniqueName().
-
So, I tried the following ( Its in Scala, but shouldn't be a problem
to
read):
try {
val env = new java.util.Hashtable[String, String]
env.put(Context.INITIAL_CONTEXT_FACTORY,
bitronix.tm.jndi.BitronixInitialContextFactory);
val ctx = new InitialContext(env);
val ut1 : UserTransaction = (ctx.lookup(
java:comp/UserTransaction
)).asInstanceOf[UserTransaction]
} catch {
case ex: Exception = ex.printStackTrace()
}
But still getting the same problem as before at line val ut1 :
What I do not get is that the Bitronix API says that the standard URL
is java:comp/UserTransaction, but its somehow not found !?!?!?
Any ideas ?
Cheers, Rob.

From your source code, I guess you used bitronix.

Hi all,
I'm a newbie for drools.
And i want to know how to fire a subset of rules in KB, suppose there
are three rules named A,B,C, and I want to fire rule A only.
by the way,
suppose there is a drl file containing rule, and i have set up KB, and
call fireAllRules through statefulKnowledgeSession. After that, the rule
file is changed, how to load rules dynamicly?
Is there any solution?
Thanks in advance!
best regards.

Hi,
I'll take a crack at you first question
Check out Agenda Filters:
http://legacy.drools.codehaus.org/Agenda
The example listed is using Rule Names, but you can use the following to
look at Meta Attribute values instead:
AgendaFilter filter = new AgendaFilter() {
@Override
public boolean accept(Activation activation) {
// Filter out rule Hello World from Sample.drl for execution
if (activation.getRule().getMetaAttribute(Purpose).equals(Print
Hello
World)) {
return true;
}
return false;
}
};
On your rules, you'll want to add a meta attribute for groups A, B, and
C. Here's an example:
rule Hello World
@Purpose(Print Hello World)--- THIS IS YOUR META-ATTRIBUTE
when
m : Message( status == Message.HELLO, myMessage :
message )
then
System.out.println( myMessage );
m.setMessage( Goodbye cruel world );
m.setStatus( Message.GOODBYE );
update( m );
end

Look at the line 58 of RulesTest class and you will find the problem. Try to
always analyse the stacktrace if there are no drools classes involved, then
it is not a Drools error. And remember, the debugger is your friend ;)
Best,

This has nothing to do with Drools. It looks like you are giving Writer bad
input perhaps??

Hi,
I am trying out this example from the book :
public class Room {
private String name
// getter and setter methods here
}
public classs Sprinkler {
private Room room;
private boolean on;
// getter and setter methods here
}
public class Fire {
private Room room;
// getter and setter methods here
}
I load 2 input files: 1. with data of fire and Room { f1, r1;f2, r2}
2. with data of sprinkler and Room { ? ?, r1; ?
? , r2}
I am writing rule ? if fire exists in room start sprinkler? { so if f1 and
r1 in this case: I should get s1, r1 }
when
Fire($room : room)
$sprinkler : Sprinkler( room == $room, modified == false )
Then
$sprinkler.setmodified(true);
modify( $sprinkler ) { setSprinkle( ?s1? ) };
end
But this gives me error:
Exception in thread main *java.lang.NullPointerException*
at java.io.Writer.write(Unknown Source)
at com.org.RulesTest.main(*RulesTest.java:58*)
From what I observed this rule is not getting fired at all.
I want this rule to be fired on the data in my second input file.
The rules for my first input file get executed properly.
Can any1 tell me where I am going wrong??
Is there any way in which we can use the modified data { after rules are
fired on the first input data and it is modified}to fire another set of
rules on the same input depending on the next input file???
Thank you.

Robert,
Try this:
create a directory called META-INF in your classpath
in that directory, add a file called jndi.properties
in that file, add the line:
java.naming.factory.initial=bitronix.tm.jndi.BitronixInitialContextFactory

Re: [rules-users] Exception using persistence
I had this in before, I put now Manuels and your last advice back in, now
the code looks like (I put it to Java - you never know):
public static void main(String[] args) throws SystemException,
NotSupportedException, NamingException
{
BitronixTransactionManager tm =
TransactionManagerServices.getTransactionManager();
tm.begin();
KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource(processes/process4.rf),
ResourceType.DRF);
KnowledgeBase kbase = kbuilder.newKnowledgeBase();
PoolingDataSource ds = new PoolingDataSource();
ds.setUniqueName(jdbc/processInstanceDS);
ds.setClassName(org.h2.jdbcx.JdbcDataSource);
ds.setMaxPoolSize(3);
ds.setAllowLocalTransactions(true);
ds.getDriverProperties().put(user, sa);
ds.getDriverProperties().put(password, sasa);
ds.getDriverProperties().put(URL,
jdbc:h2:file:/NotBackedUp/data/process-instance-db);
ds.init();
UserTransaction ut = (UserTransaction)(new
InitialContext()).lookup( java:comp/UserTransaction );
ut.begin();
// create the entity manager factory and register it in the environment
EntityManagerFactory emf =
Persistence.createEntityManagerFactory( org.drools.persistence.jpa );
Environment env = KnowledgeBaseFactory.newEnvironment();
env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );
// create a new knowledge session that uses JPA to store the runtime state
StatefulKnowledgeSession ksession =
JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env );
int sessionId = ksession.getId();
// invoke methods on your method here
ksession.startProcess( Process4 );
ksession.dispose();
}
I extended BitronixInitialContextFactory to
public class ExtendedBitronixInitialContextFactory extends
BitronixInitialContextFactory
{
public ExtendedBitronixInitialContextFactory()
{
super();
}
}
so I can set easily a breakpoint in the constructor to make sure this will
be called and
put that into the jndi.properties
(java.naming.factory.initial=com.rob.tests.ExtendedBitronixInitialContextFactory).
But I still get the same exception:

Re: [rules-users] Multiple Object referencing error
Hi,
Sorry about not posting the code. My mistake.
Classes :
public class Room {
private String name
private int number;
// getter and setter methods here
}
public classs Sprinkler {
private Room room;
private boolean on;
// getter and setter methods here
}
public class Fire {
private Room room;
// getter and setter methods here
}
I load 2 input files: 1. with data of fire and Room { f1, r1;f2, r2}
2. with data of sprinkler and Room {n/a,r1,n/a,r3}
I am writing rule if fire exists in room start sprinkler { so if f1 and r1
in this case: I should get s1, r1 } But since no sprinkler in r2 , That data
should not get outputted.
I want my ouput file to look like:
NameNumber
Xyz 1
# xyz is my room name and 1 is the room number : r1(xyz,1) . But I am unable to
delete entries.Is there anyway I can do it?
#only this should appears as the other room does not have a sprinkler.
when
Fire($room : room)
$sprinkler : Sprinkler( room == $room, modified == false )
Then
$sprinkler.setmodified(true);
modify( $sprinkler ) { setSprinkle( s1 ) };
end
Error:
I am getting the error at a place where I am trying to write back from my
working memory to my output file.
It is happening because the second rule to turn on the sprinkler does not work
and as a result a null value is getting stored.
Is it possible that there can exists 2 different Room() objects with the same
room.name ??
Because the room objects are getting stored from different files to the working
memory ??
Do you think it better to store room objects in a separate list??
I store all information into a list and load that into the memory.
Am I going wrong here?
Please help.
Thank you.

[rules-users] Flow exception handling
Hi Everyone, I'm trying to get my head round how to use Drools Flow in a reliable manner. In particular I'm trying to understand how to defensively program against exceptions thrown within Action Nodes (eg NullPointerException). In 5.0.1 it is absolutely horrendous as if the action throws an exception while being called from fireUntilHalt then the exception just gets swallowed up with no way for the application to detect it at all. In 5.1.0-M1 it is marginally better in that the exception is thrown through fireUntilHalt (or whatever other location it is called from). However there seems to be absolutely no way to determine which process is at fault - the process isn't even marked as Aborted and still exists in the session, also if you call fireUntilHalt again it just seems to sit there and not run any more processes. It doesn't even throw an IllegalState type exception to tell you it isn't valid to call it after an exception has occurred. What I was expecting was that processes work in a similar way to java threads. If a particular process encounters an exception I would expect that: 1. The process is marked as aborted. 2. An appropriate method on a process event listener is called. 3. Any other processes in the session will attempt to continue to run. Clearly depending on your session configuration the working memory may be in an invalid state and other processes may be stuck waiting for an event to occur which never will, but this is a design decision for the application developer, in many other cases processes will be stand alone keeping all their data internal to themselves. Is there some other functionality of Drools that I am missing or should I raise a JIRA for this (if one doesn't already exist).

[rules-users] Multiple Files Problem
Hi,
I need to load data contained in many Lists as my input.
In what way is it possible for me to load multiple lists in drools?
I am doing this currently:
public void runStatelessRules(String[] rulesFiles,String
dslFileName,CollectionObjectal,
String ruleFlowFileName) throws Exception {
RuleBase ruleBase = loadRules(rulesFiles);
StatelessSession workingMemory = ruleBase.newStatelessSession();
workingMemory.execute(al);
}
CollectionObjectal is my input. In this I have dumped data from multiple
arrayLists.
All rules get processed accurately.
But creates a mess when I need to write to my output file.
Is it in some way possible for me to give separate lists to load to my working
memory???
Please help. Thanks in advance.

[rules-users] data manipulation
Hi all, We recently implemented Drools in a mortgage application process. The primary task of the business rule engine was to determine the fraud risk of an application. The application is delivered in XML format. We noticed that we were implementing a lot of data manipulation actions in the drl file itself. For example, the calculation of total income by calculating the sum of a number of elements or calculating the distance between two geo-locations based on zip codes. The actual evaluation rules acted on this 'derived' information. When looking back the drl file contained a lot of code and looked pretty complicated compared to the actual evaluation rules. My question is, what is your opinion on data manipulation or transformation within the drl file? If the drl file is not the best place for this, what would you suggest for data manipulation? Thanks, Betto ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] data manipulation
For data manipulation you can use something like apache camel. To transform the information and then make inferences over it.

Re: [rules-users] data manipulation
You may also want to look into a JAXB type binding implementation, or something simpler like XMLBeans at Apache (http://xmlbeans.apache.org/). You would then be able to simple push those populated objects (based on the Mortgage's XML schema) directly into working memory and only write rules to process plain beans. Mauricio's suggestion is also really good. :) best wishes, Andrew On Jun 8, 2010, at 5:25 PM, Salaboy wrote: For data manipulation you can use something like apache camel.

Re: [rules-users] alerts in drools
Why do you need alerts for? If you are trying to see somehow the execution
of a group of rules, you can attach an AgendaEventListener to your session:
ksession.addEventListener( new AgendaEventListener(){
}
);
