[rules-users] workflow rules in process order example
Hi, looking at the process order example in Drools 5.0 I wonder what workflow_rules.drl is doing? It relies on implementation details but seems not to be used on execution. thanks, gryf ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Drools Guvnor DB setup issue.
What error? Can you paste the server log?
Maybe it's the white space before 'brms' in your connection url? Maybe
you didn't provide the driver jar?
Cheers,

RE: [rules-users] How to execute the SQL query using drools
You have not clearly defined when you want to execute SQL queries. If you want to access a DB from the LHS you can use the from keyword. Note the results need to be time-constant i.e. not change on successive calls. If you want to access a DB from the RHS it is plain Java (or MVEL depending upon your rule dialect).

How is the method declared?
In other words: is mvel correct in not finding that method with that
declaration because it doesn't exist?
If the method uses different formal argument types, have you tried
explicitly casting the actual arguments to the formal types?

Re: [rules-users] wait states, jpdl and nlp
Hi Lemel, Yes ruleflow support wait state in the same way that jBPM does. With a different approach maybe, but you can do exactly the same with Ruleflow. There is also a limited support for jPDL inside ruleflow, that means, that you can take your jPDL process and run it with ruleflow. But, if you are thinking in replace the old jPDL to Ruleflow you can do it.

[rules-users] Rule overriding
We are building a rule engine that will serve multiple companies. Many of the rules are common but there are some situations where the common rules need to be overriden by rules that are specific to a particular company. Each company has it's own rulebase that we create with packages that are configured for that company. I know that rules with the same name will override previous rules if they have the same package name. We could make that work if we compile the rules at runtime but I would like to deploy the binary packages from Guvnor. Has anyone come up with a solution for this?

I cannot seem to call a static method on one of my classes and keep
getting this error:
[Error: Failed to compile: 1 compilation error(s):
- (1,44) unable to resolve method using strict-mode:
com.aps.syslog.logging.manager.LoggingManager.runLoggingTest(java.lang.String,

When I call the static method:
LoggingManager.runLoggingTest (23223, transaction);
Where the first argument can be any string and the second is a custom class
that I isntatiated earlier in the RHS with no problems.
Is the problem strict-mode? Or something else?
LogginManager.runLoggingTest is a static method but do I perhaps have to do
something like:
$lm : LoggingManager()
Then call the static method using:
$lm.runLoggingTest (23223, transaction);
Or something along these lines (I did try this but it failed as well).
Thanks,

Re: [rules-users] Rule overriding
Kent, Not sure I understand your question. Does not matter if your rules are in source format or binary format from guvnor. As long as they have the same package name + rule name, a new rule will override a previous rule... []s Edson 2009/6/23 k...@chryslerfinancial.com We are building a rule engine that will serve multiple companies. Many of the rules are common but there are some situations where the common rules need to be overriden by rules that are specific to a particular company. Each company has it's own rulebase that we create with packages that are configured for that company. I know that rules with the same name will override previous rules if they have the same package name. We could make that work if we compile the rules at runtime but I would like to deploy the binary packages from Guvnor. Has anyone come up with a solution for this?

Re: [rules-users] wait states, jpdl and nlp
Let me try to answer the first set of questions: - does RuleFlow support arbitrary long wait states, in other words, can I call long-running services from it asynchronously? Of course, there are various nodes that behave as some sort of wait node. For example, a work item node waits until the work it has requested is completed (a human task node is a special case of this). An event wait node (or the more generic wait state that will be introduced in 5.1) allows you to wait for some condition (or manual trigger), etc. If you want to call a long-running service asynchronously, take a look at the work item node and use a work item handler that completes the work item asynchronously. - if not, can I put JPDL node in rule flow process definition, and if yes, how? If you would want to extend the current set of nodes, that would be possible, but you would need to dive into the internals to do that. But I don't think that is necessary. The work item and wait state nodes should be all you need I think.

RE: [rules-users] How to execute the SQL query using drools
Your requirement isn't that clear however here's a few thoughts:- Data can be inserted into the Rule Engine either externally (i.e. WorkingMemory.insert) or internally (using from). If you use DSL you can make DRL more human readable; although neither are binary format in the first place. Drools will fit your requirement, but without knowing your use-cases better I can't say whether it would be the best fit. Perhaps if you can give a more detailed use-case the group would be better able to comment further. Please also ensure your emails go to the group http://www.jboss.org/drools/lists.html Finally, do read the documentation, you would probably be able to answer your own questions.

The actually rule name and package are a lot longer, I changed them here
for brevity and because I don't believe the names themselves are relevant.
This exception is being thrown intermittently when this rule, which
contains an accumulate function is called. I say intermittently because
it does not happen every time the rule is run. As far as I can tell the
ClassCastExceptions only happens when the computer that the rules are
running on is under load.
A few more details before I post the rule itself. The rule base that I am
building consists of 2 drl files. Both of the files have the same package
declaration at the top. The 2 packages are built separately using
PackageBuilder then combined using RuleBase.addPackage() on both packages.
Also, I'm not sure if this is relevant, but this scenario takes place in
a web application where the two package objects are only built once (for
performance) but each user session creates a new RuleBase and adds the
packages. The individual sessions then create stateful sessions from the
rule base.
This is the rule that I believe is causing the issue.
rule My Rule
salience 50
dialect java
no-loop true
when
$module : Module( selected == false, required 1, $size :
required )
$list : ArrayList( )
from accumulate( PotentialMatch( module == $module, $slot
: slot ),
init( List result = new ArrayList(); ),
action( result.add($slot); ),
reverse( result.remove((Integer)$slot ); ),
result( result ) )
eval( countThem($list, $size) != $module.setMatchCount() )
then
modify( $module ) { setMatchCount(countThem($list, $size)) };
end
As I'm typing this I realize that there is another way to write this rule
using collect. I'm not sure why it was written this way, but since I have
already come this far, has anyone had any experience with the Drools 4
generated code throwing ClassCastExceptions?
Thanks,

Re: [rules-users] Link for drools-server module
if you are able to create your packages, then you do not need the guvnor, since guvnor merely automates it for you. create a xxx.properties file in your classes folder ( where xxx is the package name ) This is documented in the guvnor documentation -- search for drools-server or look at the properties file attached in the JIRA provided. then, you are all set when you make a web service call to the URL as shown in the rb file i had attached.

Re: [rules-users] workflow rules in process order example
Gryf, The order example can be executed using what we call advanced execution mode. In that case, you are not automatically going from one node to the other in your process all the time, but we allow other rules to intervene and possibly override the default behaviour. The workflow_rules you are referring to are describing the default behaviour. The logging rules and assignment rules in the example show how to add additional behaviour in this advanced execution mode. However, because advanced execution mode is still experimental (as very powerful and the user needs to know much more internal details to use them effectively), so we did not enable it by default. If you want to enable advanced execution mode, add this line before adding the knowledge packages to the knowledge base: ((InternalRuleBase) ((KnowledgeBaseImpl) kbase).getRuleBase()) .getConfiguration().setAdvancedProcessRuleIntegration(true); Kris Quoting g...@hippogrif.dk: Hi, looking at the process order example in Drools 5.0 I wonder what workflow_rules.drl is doing?

Re: [rules-users] Class Cast Exception in Drools 4 Generated Accumulate Method
Steve,
What versions of MVEL and Drools are you using?
Comments:
* You can not share packages between rulebases. You can share rulebases
among sessions. So, I strongly advise you to change your application to
build the rulebase once, and have the web sessions only create the rule
session every time... not the whole rulebase. Since packages have their own
classloaders and everytime you create a rulebase you merge such
classloaders, the problem might happen (CCE) exactly at the time you are
creating the rulebase concurrently. Drools 5 allows you to share packages,
although I still prefer to not do it and share only the rulebase.
* You can not use collect in this case, because you are creating a list of
$slot, not a list of PotentialMatch. Although, it is extremely easy to
create an accumulate function for that. Drools 5 includes 2 accumulate
functions: collectSet and collectList for that. If you want, just get the
class from Drools 5, fix the imports to use the classes from Drools 4 and
use it. Except for the imports you should not have any problem. Your rule
would look like:
*rule* My Rule
*salience* 50
*dialect* java
*no-loop* *true*
*when*
$module : Module( selected == *false*, required 1, $size :
required )
$list : List( )
*from* *accumulate*( PotentialMatch( module == $module,
$slot : slot ),
collectList( $slot ) )
*eval*( countThem($list, $size) != $module.setMatchCount() )
*then*
*modify*( $module ) { setMatchCount(countThem($list, $size)) };
*end*
* Finally, your eval looks odd to me, but anyway, don't have enough details
to advise you on that.

Re: [rules-users] Class Cast Exception in Drools 4 Generated Accumulate Method
Edson,
Thanks for the quick response!
I'm using Drools 4.0.7 and mvel 1.3.1
Thanks for the tip about packages and rulebases. I'll make sure to change
that in our code.
As far as changing the accumulate to collect, I can easily work around
that selector returning a list of PotentialMatches instead of Integers. I
made that change and have been unable to create the ClassCastException
since. I'm still not certain that the problem is resolved due to its
random nature, but I'm hoping that it is patched enough for now until we
can make the rulebase change you mentioned.
Thanks for the info about Drools 5. I'm currently in the process of
converting to Drools 5.
You're right the eval does look odd, but it is working for the time being.
This rule is in one of the first features I implemented using Drools, so
it is probably not done in the best way possible. I'll keep an eye on it
if I do not get this issue resolved some other way.
Thanks again!

Steve,
What versions of MVEL and Drools are you using?
Comments:
* You can not share packages between rulebases. You can share
rulebases among sessions. So, I strongly advise you to change your
application to build the rulebase once, and have the web sessions
only create the rule session every time... not the whole rulebase.
Since packages have their own classloaders and everytime you create
a rulebase you merge such classloaders, the problem might happen
(CCE) exactly at the time you are creating the rulebase
concurrently. Drools 5 allows you to share packages, although I
still prefer to not do it and share only the rulebase.
* You can not use collect in this case, because you are creating a
list of $slot, not a list of PotentialMatch. Although, it is
extremely easy to create an accumulate function for that. Drools 5
includes 2 accumulate functions: collectSet and collectList for
that. If you want, just get the class from Drools 5, fix the imports
to use the classes from Drools 4 and use it. Except for the
imports you should not have any problem. Your rule would look like:
rule My Rule
salience 50
dialect java
no-loop true
when
$module : Module( selected == false, required 1, $size :
required )
$list : List( )
from accumulate( PotentialMatch( module == $module,
$slot : slot ),
collectList( $slot ) )
eval( countThem($list, $size) != $module.setMatchCount() )
then
modify( $module ) { setMatchCount(countThem($list, $size)) };
end
* Finally, your eval looks odd to me, but anyway, don't have enough
details to advise you on that.

Re: [rules-users] Class Cast Exception in Drools 4 Generated Accumulate Method
Steve and all users of Drools 4,
Although earlier versions of Drools used mvel 1.3.1, in version 4.0.7 we
updated to mvel 1.3.9. There are several fixes from 1.3.1 to 1.3.9, so I
strongly suggest you all update. There are even newer versions of mvel
1.3.x, but the one I personally QA'd and found no problems was 1.3.9.
Updating is just a matter of replacing the old jar for the new jar in the
classpath. There are no API breaks or any other known problem.

Where the first argument can be any string and the second is a custom class

Is the problem strict-mode? Or something else? LogginManager.runLoggingTest

$lm : LoggingManager()
Then call the static method using:

Although you don't need it if you are using straight forward insertLogical() call in the consequence, if you try to pass the ruleContext as parameter to an external method/function, you need the method.

[rules-users] Need help with setFocus
Hi All,
Need some help with understanding setFocus.
I have the following use case:
if (condition1) {
if (condition2) {
} else if (condition3) {
} else if (condition 4) {
}
}
if (condition5) {
if (condition2) {
} else if (condition3) {
} else if (condition 4) {
}
}
I created 3 rules (rule2, rule3, rule4) for checking condition2, condition3,
condition4 and
created 1 agenda group (groupX) for them.
I created 2 rules (rule1, rule5) for checking condition1, condition5 and
created 1 agenda group(groupY) for them.
rule rule1
agenda-group groupY
when
//
then
drools.setFocus(groupX);
end
rule rule3
agenda-group groupX
activation-group someActiveGroup
when
//
then
//
end
From the java code:
ksession.getAgenda().getAgendaGroup(groupY).setFocus();
Problem: The first time, drools.setFocus(groupX) is invoked, I see that
it's working fine. rule2 or rule3 or rule4 get triggered. But, the SECOND
time that drools.setFocus(groupX) is invoked, I don't see that any rule in
agenda-group groupX is being invoked...even though one of the rule's LHS
explicitly matches...thinking that the activation-group is cancelling all
the activation's (after one rule in that activation group is fired), I even
removed the activation-group statement. But, it didn't help...ideally, I
would like to bunch rule2, rule3, rule4 in one activation group.
Can you please let me know as to why the second invocation of setFocus is
not working? I even tried to remove everything in LHS of rule2/3/4, to see
if the second invocation would work...it doesn't...
Thanks!!
