[rules-users] Extracting an object in the working memory for multiple times
I asserted 3 object in the working memory and I iterate it to check a value in that object for a condition in the first rule. I need to iterate all the objects in the working memory again for another condition in the second rule. But the objects are not iterating in the second rule. There is any condition that an asserted object can be used only once? -- View this message in context: http://www.nabble.com/Extracting-an-object-in-the-working-memory-for-multiple-times-tf3871503.html#a10968613 Sent from the drools - user 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] Use of the same reference in multipe rules
I asserted 3 class (Class1, Class2, Class3) in the working memory. I make an
reference for the class (Class1) in the first rule. Is it possible to use
the same reference in the 2nd rule?
Eg:
[when] class : Class1() eval(class.getVarName1() == {value1});
[then] .do something...
[when] eval(class.getVarName2() == {value2});
[then] ...do something
My requirement is to use the same class (Class1) in all the rules. I don't
want to iterate other two classes (Class2 Class3) in rule 2.

Re: [rules-users] Help Needed.
Hi Rajesh,
You MUST use the org.drools.util.BinaryRuleBaseLoader to load a
precompiled binary package into your RE classes.
public void testLoadAndExecBinary() throws Exception {
Person p = new Person();
BinaryRuleBaseLoader loader = new BinaryRuleBaseLoader();
loader.addPackage( this.getClass().getResourceAsStream( /
RepoBinPackage.pkg ) );
RuleBase rb = loader.getRuleBase();
StatelessSession sess = rb.newStatelessSession();
sess.execute( p );
assertEquals(42, p.getAge());
}

hi ,
First of all congratulations to you for JBRMS release.
You and your team has done a great job.
Micheal I am facing some issue , when I use jbrms.
I have written a sample technical rule by following all the steps
as mentioned in the document.
I am able to download binary package also,but when I tried to use
this package in my rule engine class using following code it’s
giving some error like …
FileInputStream fis = new FileInputStream( C:/drools/
TestPackage.pkg );
ObjectInputStream ois = new ObjectInputStream( fis );
Object objPackage = ois.readObject() ;
when ObjectInputStream object tries to read the object , its
giving some an error
ois.close();
fis.close();
Could you please help me out for this …

Re: [rules-users] Rule Flow vs jBPM
A better question should be why doesn't jbpm leverage rules :) jBPM does many things we don't do, it's transactional and persistable, it has a number of services configured for nodes (tasks etc) and is generally better aimed at long lived orchestration and choreography and of course it is aimed at various workflow/bpm standards support. Firstly the GUI side was donated and already partially integrated, it was a few days work to get that fully integrated or weeks of work (maybe more) to refactor much of jBPM designer to allow us to integrate and then ofcourse the further work to better supported our tooled environment. Our GUI side offers a far more integrated approach for rules, where as jBPM has more pojo focused, still leaving the author to implement interfaces and then specify the class as a callback within the configuration on that node - so it's far more low level. Secondly if we where to leverage jBPM to do the state management of the executions we would end up with two engines running which would need to be bridged, contexts would have to be mapped and the tooling is not aimed at ruleflow but more orchestration of services - over all there is an impedenance mismatch which would actually make this more complex, the implementation slower and generally it would take longer to do. RuleFlow is a natural extension of the approached use by agenda groups and its hooked tightly into the engine to get the best performance. Mark Ming Fang wrote: The Rule Flow implementation looks similar to jBPM's Graph Oriented Programming framework. http://docs.jboss.com/jbpm/v3/userguide/graphorientedprogramming.html Was there any reason why it was not leverage? ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
