Re: [rules-users] Fact Names in a Model
Even if you get the packages using REST API, you still need to add them to
a kbuilder (you don't need to have multiple kbuilders. 1 kbuilder can
contain multiple packages).
What you can do if you don't want to manually add all the packages to a
kbuilder is to create a change-set, which is basically an xml pointing to
all the resources you want to add. Then, you add the change-set to the
kbuilder with ResourceType.CHANGE_SET. For more information about
change-sets, please refer to the documentation.

Re: [rules-users] How Add all packages to KnowledgeBuilder.add(drl or pkg or xsd,..);
Part of the solution was mentioned here: http://drools.46999.n3.nabble.com/Listing-all-packages-present-in-gunvor-repository-td3581480.html (maybe the response didn't appear in nabble yet) If you don't want to maintain your change-sets in your applications, then you need to wait until this pull-request is applied (It must be accepted first :) ) https://github.com/droolsjbpm/guvnor/pull/26 Right now, Guvnor only publishes 1 change-set per package. In some situation, like yours, this is not enough. Sometimes you need to have a change-set pointing to: - specific assets inside a specific package - specific assets inside multiple packages - multiple packages (your case) - a mix of all the options This is what the mentioned pull-request does. It adds a new change-set editor in Guvnor that allows users to create their own change-sets. Change-sets then can be accessed from your applications using HTTP (like any other asset through REST).

[rules-users] [MVEL] the data converter does not work
Can someone tell why the data converter does not work at all and what is the
reason we make the data converter to value assignment statement only?
public void testDataConverter() throws Exception {
OptimizerFactory.setDefaultOptimizer(OptimizerFactory.SAFE_REFLECTIVE);
DataConversion.addConversionHandler(Date.class, new MyDateConverter());
Locale.setDefault(Locale.US);
Cheese cheese = new Cheese();
cheese.setUseBy(new
SimpleDateFormat(dd-MMM-).parse(10-Jul-1974));
MapString, Object variables = new HashMapString, Object();
variables.put(cheese, cheese);
Serializable compiledExpression = MVEL.compileExpression(cheese.useBy
== '10-Jul-1974');
boolean result = MVEL.executeExpression(compiledExpression, variables,
Boolean.class);
assertTrue(result);
}
Here is what I can see from the code, at the end this method will be called,
would it be nice to allow the data converter here?
private static Boolean safeEquals(final Object val1, final Object val2)
{
if (val1 != null) {
return val1.equals(val2) ? Boolean.TRUE : Boolean.FALSE;
}
else return val2 == null || (val2.equals(val1) ? Boolean.TRUE :
Boolean.FALSE);
}

Re: [rules-users] Problems with Domain Specific Language in eclipse
Personally - I would rather get an error when I make a mistake (e.g. do not write the DSL correctly) than get get an error for writing perfectly valid code. [Swindells, Thomas] But it isn't valid DSL code. DSL is normally written by business users who don't know anything about DRL, this is the target audience and for these people you don't want them to be able to accidentally do additional logic. Eclipse does support a DSL expansion window which allows you to find issues like misspellings. The current approach requires a total commitment to DSL even if you want to use it under rare circumstances. I did note your suggestion about prefixing with '', but then my RHS looks different in rule files where I use DSL than it does in files where I do not use DSL (something I would rather avoid). Your entire file looks different in DSL than in a DRL anyway, it's a different language that allows embedding DRL, personally I think it is a good feature to explicitly need to identify that you know what you are doing.

All you need to do is create an account for yourself in the JIRA home

That is the best way as it provides tracking and avoids your code being

[rules-users] Temporal operators for point-in-time events
Apologies for the stupid question, but I haven't seen anything in the documentation regarding this and I want to verify my solution. Say I have a point-in-time event (i.e., duration of 0) that I want to correlate to another point-in-time event. I want a rule that will activate if the timestamp of one is greater than or equal to the other, basically after or coincides. I wrote a test using the following rule and it seemed to work: rule Greater Than or Equal when $e1 : TestEvent( $id : id ) $e2 : TestEvent( id != id, this after[0ms] $e1 ) then System.out.println($e2 + is greater than or equal to + $e1); end I realize this rule will fire twice if the event timestamps are equal, but it's just for demonstration purposes; my question is specifically about the after[0ms] part. Is this the way to go to accomplish what I need? It seems so simple but I have this annoying feeling that I'm missing something. On a slightly related topic, is there an updated version of the temporal operators image from the Drools Fusion homepage? It is a great visual description of the operators and I want to print it out and post it at my desk, but it doesn't include all of the operators.

Re: [rules-users] Can Drools supply large Knowledge Base?
There are a few things going on in these discussions: rule size vs number of facts vs number of rules. On the latter two, memory thrashes and then crashes when too much is brought into memory at once. You can use JVM options to increase memory size, variable space size, etc. The upper limit for the number of rules is based upon the size of the rule. However, if you are planning to have more than thousands of facts or rules in memory at once, you may have problems in a 32 bit JVM. Using a 64 bit JVM helps. On rule size, I have had clients with rules like if any of these symptoms then you could have cancer. The number of conditions on such a rule is over 100. DROOLS can handle rules of such complexity, although they are difficult to debug in any language. -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-Can-Drools-supply-large-Knowledge-Base-tp3569354p3583004.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
[rules-users] Stateless session in drools server keeping classes around?
Hi, I'm using drolls 5.3 server with one rule in a _stateless_ session. I am sending a POJO to the server, having it check a few attributes, modify the attributes of the bean as needed then return the result. I have this working and get back an execution results object like I need. The problem is that when I send the batch execution command to the server a number of classes stick around with each call (as shown in jconsole). Memory grows with each call until I run out. (I see garbage collection taking place so that doesnt seem to be the problem - and if I stop sending events to the server, the memory is never returned). I figured with a stateless session I wouldnt need to worry about this, anyone have thoughts about why this is happening? I am trying to do this quickly, and don't want to call dispose/retract (the whole reason I'm using stateless). knowledge-services.xml: drools:ksession id=ksession1 type=stateless kbase=kbase1 node=node1/ my code that builds the command: list cmds = new arraylist InsertObjectCommand icmd = CommandFactory.newInsert(myBean) icmd.setOutIdentifier(inserter) icmd.setEntryPoint(DEFAULT) cmds.add(icmd) FileAllRulesCommand farc = new FileAllRulesCommand() cmds.add(fileAllRulesCommand) BatchExecutionCommand command = CommandFactory.newBatchExecution(cmds,ksession1) ..

Re: [rules-users] Temporal operators for point-in-time events
Thank you, Edson. I saw the written documentation but since the default after interval is [1ms, infinity], I wanted to check for the specific [0, infinity] case that there wasn't a better suited operator. I do have a (somewhat related) question about the documentation when compared to the diagram(s). Take, for example, the finishedby operator. The documentation says A finishedby B means A starts before B and A and B finish at the same time. However, the diagram shows A starting *after* B and A and B finishing at the same time. The other related operators (finishes, starts, startedby) all have the same discrepancy. (Additionally, the second diagram in the presentation includes a different definition for the finishes operator than the first diagram. Maybe it should be startedby?) My tests show me that the written documentation is correct and the diagram is not. Unless I am reading the diagram incorrectly; if that is the case, can someone explain it?

[rules-users] Drools 4.0.7 - Serialization of Rules and Facts
I've inherited a rule engine implementation based on Drools 4.0.7 in which we're seeing a portion of rules failing to fire after we serialize then deserialize rules and facts across the restart of our application server. Here is our current implementation: serialization === 1. All facts are persisted to database tables from Events received via an implementation of WorkingMemoryEventListener 2. All Rules are persisted to database tables as a collection of rule arguments deserialization after an app server restart, a new RuleBase is created, and RuleBase.newStatefulSession() is called 1. Rule arguments from db table are passed to an in-memory process that writes a plain text DRL file 2. DRL string is built to a Package, then installed as a new rule within the RuleBase 3. each individual fact is loaded from db table and inserted into the newly created working memory (StatefulSession) I do not believe this is a valid way of de/serialization. Reading the tests that ship with Drools 4.0.7, as well as the documentation, it seems the proper way is to use Java object serialization with both the RuleBase and WorkingMemory - is that correct? Assuming that my current serialization is incorrect, I'm investigating how best to repopulate the newly created RuleBase and working memory so that rules reliably fire. What I am seeing is that rules do not fire in a non-deterministic fashion after repopulating the new working memory as described above. Are there any suggestions for other paths to attempt?

[rules-users] Store a Map in Country Enumeration
Hi Manstis,
I created enumeration for states and countries as
'Address.country':(new com.sample.DataList()).getMyCountriesList()
'Address.state[country]' : '(new
com.sample.DataList()).getStateList(@{country})'
It is showing drop-down list in guided rule editor for countries as
US,UK,INDIA
And when I select state it is also successfuly displaying basedon country..
Suppose if I selected country US..states are being displayed based on US.
But if i changed my selection of country US to UK..states drop-down list is
not getting refreshed.Guided editor showing same as Newyork,Washington
etc...It is displaying UK countries only when I clicked on Newyork(states
drop-down list).It means *I mean to say automatic refreshment is not being
done* http://drools.46999.n3.nabble.com/file/n3584640/Capture1.png

Re: [rules-users] Cross Reference Utility
I posted a class doing that a few days ago on this list. The problem is that it relies on classes in Drools' instable API, and it was originally written around 5.1.1, so it may have aged some. -W On 13/12/2011, ronalbury ronalb...@gmail.com wrote: Is there a cross reference utility, that will allow me to easily find the rules which reference a specific class and/or specific attribute? I'm hoping for something like the standard Java 'references' report. I'm guessing (based on what I've read) that the Drools compiler generates a bunch of Java classes behind the scenes ... is there any way to get it to leave those Java artifacts so that I could get a 'references' report from them?

Re: [rules-users] Many to many matching using Drools rules
You can collect objects of both classes with matching id and date. Each of these collected objects has the original id and date a list of amount figures. Pairing the collected object from repository and accounting is simple. Then, you'll have to implement an algorith that selects the items from both sides in an acceptable way. I presume that one or more items from one side must exactly be equal to one or more items from the other side, which may not always be possible even though there would be coverage of an item of one side by items on the other side (e.g. 7,11 vs.3,3,3,3). But assuming that you detect matching sums, you retract the original facts. In any case, the collected objects must be retracted, too, at the end of the processing. (Some details depend on the way the original facts are inserted.)

One scenario I have no clue to implement in Drools is that I need to find x transactions from repository, to match y transactions from accounting, while existing repository transactions and accounting transactions are bigger than x and y. Does anybody have experience to do similar thing in Drools?
