[rules-users] Free Form DRL through BRL in guided decision table
Does the workbench extended entry guided decision table support this kind of syntax: ServiceLineStatusInfo( claimStatusCodes contains $param ) Where $param is replaced with the value of the column? When I add that through New Column-Add a Condition BRL Fragment-Free Form DRL all I get is a checkbox column. Is there a way to set that up so that it allows entry and does the substitution? I know the line above could be built easily in other ways. It is just an example to illustrate. I have some more complex logical constructs that I'd like to do in straight DRL fragments if possible. Thanks, Joe ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Free Form DRL through BRL in guided decision table
Thanks Mike. I see that in the Rule Templates section of the docs. If you want
I’ll add that the Guided Decision Table of the documents as well and issue a
pull. Let me know.

You need to use a Template variable in the BRL fragment.
ServiceLineStatusInfo( claimStatusCodes contains @{param})

You're inserting an object of type TClaim but your rule is written against
Claim. Change your rule to TClaim and maybe it will work.

Re: [rules-users] 6.0.1.F Need help in getting recanned rules into new session
Try a version range or a SNAPSHOT. LATEST doesn't work in 6.0.1 for the
scanner.

Subject: [rules-users] 6.0.1.F Need help in getting recanned rules into new
session
I've have been unable to figure out how to get drools to rescan and then use
the updated rules in a new session. I currently have to restart jboss to pick
up the changes. The scanning seems to happen, but I don't see the changes that
should be included.
I have looked at lots of example code on the web and also at the Switchyard
source. When I do this in tandem with SY, I can get it to work, but I
need/want to have it work on its own.
I have tried some different combinations with no luck.
In addition to the why doesn't it work, I would like to clearly
understand:
Do I need a KieBase, or should I just be creating sessions off of the container?
What do I need to have in Envinonment?.
What do I need to have in ksessionConfiguration?
Related, what is the proper mechanism to pass in the Session Name?
GAD is: com.xyz.policy, cep, 1.0
Drools session is stateful and named DroolsSession, stream processing mode,
realtime
I initialized KIE with the following.
kieServices = KieServices.Factory.get();
releaseId = kieServices.newReleaseId(com.xyz.policy, cep,
LATEST);
kieFileSystem =
kieServices.newKieFileSystem().generateAndWritePomXML(
releaseId);
kieBuilder = kieServices.newKieBuilder(kieFileSystem);
kieBuilder.buildAll();
Results results = kieBuilder.getResults();
if (results.hasMessages(Message.Level.ERROR)) {
StringBuilder sb = new StringBuilder();
for (Message message :
results.getMessages(Message.Level.ERROR)) {
if (sb.length() != 0) {
sb.append( -- );
}
sb.append(message.toString().trim());
}
log(Unable to initialize KIE + sb.toString());
} else {
env = kieServices.newEnvironment();
kieContainer = kieServices.newKieContainer(releaseId);
kieScanner = kieServices.newKieScanner(kieContainer);
kieBaseConfiguration =
kieServices.newKieBaseConfiguration();
kieBase = kieContainer.newKieBase(kieBaseConfiguration);
kieSessionConfiguration =
kieServices.newKieSessionConfiguration();
kieSessionConfiguration.setProperty(sessionName,
DroolsSession);
kieSessionConfiguration.setProperty(drools.clockType,
realtime);
kieSessionConfiguration.setProperty(drools.evenProcessingMode,
stream);
Later when I determine it is time to rescan, I do the following:
kieScanner.scanNow();
System.err.println(Scanning...);
currentKieSessionThread = new
KieSessionThread(
kieBase.newKieSession(kieSessionConfiguration, env));
executorBean.execute(currentKieSessionThread);

Re: [rules-users] 6.0.1.F Need help in getting recanned rules into new session
I haven't tried ranges myself. I know for sure SNAPSHOTS work. I think you may need a bracket at the end of your range definitions.

You have to create a new session. Only new sessions will have the updated

I don't know what is different today, but LATEST is working. I think I had
too many changes going on at once, back to a good state.
(FYI, We've been cherry picking fixes from the master branch)
So, I'm getting close.
Now, I even see the message
The following artifacts have been updated: {..blah blah..}
But, what I am not seeing now is the changes in the then sections I made in
the rules (just printlns at this point). I have to restart jboss to see the
changes.
The scanner is running and according to the example shown at
http://stackoverflow.com/questions/22205945/drools-6-add-rules-to-a-running-kiesession/22208775?noredirect=1#22208775
http://stackoverflow.com/questions/22205945/drools-6-add-rules-to-a-running-kiesession/22208775?noredirect=1#22208775
it seems like the sessions should automatically update. Is that true? Or, do
I have to create a new session after the contain is updated with the new rules?

Re: [rules-users] Pojos not visible in Guided DT
Hey Mike, I'll try to reproduce again so that I can provide details before opening the Jira. It wasn't specifically related to the free form DRL I don't think. I was able to go into the admin console and revert a couple of changes to get my table back to life. I had a perm-gen problem and had to reboot so the stack is gone. The only info I have now is the error from the portal: Unable to complete your request. The following exception occurred: rowData contains a different number of columns to those provided. If you want a ticket with just that info I can open it but let me know since that isn't much to go on. I'll try again to gather a better trace.

Re: [rules-users] 6.0.1.F How to set Maven repo used by KieScanner?
I believe it pulls from however your maven install is configured. Make sure you've got the M2_HOME env variable set and pointed to your maven install. And then it should pull from whatever you have in settings.xml in maven for your repositories. I also have MAVEN_HOME set to the same path as M2_HOME but I think that was for a different project. If setting M2_HOME doesn't work try adding that one as well. -Original Message- From: rules-users-boun...@lists.jboss.org [mailto:rules-users-boun...@lists.jboss.org] On Behalf Of SrjTx Sent: Wednesday, March 19, 2014 2:05 PM To: rules-users@lists.jboss.org Subject: Re: [rules-users] 6.0.1.F How to set Maven repo used by KieScanner?

Re: [rules-users] Some basic questions/assumptions on Drools Work-bench/Guvnor
On the topic of #7. We are just adopting the Drools 6.x setup to achieve the goal you mention of business users creating and deploying business rules on their own. The challenge is allowing your users to deploy in a targeted way since the drools workbench (DWB) doesn't have the concept of a deployment scope (dev, stage, prod). Here is my current thinking on managing lifecycle in 6.x: Application Setup: - Create separate maven repositories for SNAPSHOT vs fixed version deployments and point your installed applications to those different repositories. o KIEScanners in test applications will point to snapshot versions. o KIEScanners in prod will point to version ranges like [1.3.0, 1.4.999] - Developers design and create package structure. Very important since a new Project in the DWB will require a software release - Developers design and create decision tables or guided rules for business users. Business User SDLC flow: - User creates new rules in decision tables - User validates new rules and runs analysis on rules in the DWB - When a user wants to test their rules they create a snapshot from the DWB and deploy it . Jar gets deployed to only the snapshot repo - User tests their new rules in the stage system (auto picked up from KIEScanner) - Once they are happy they remove the SNAPSHOT designation, increment version, and deploy to prod (all in DWB) - Users tests their new rules in prod (auto picked up from KIEScanner) A relatively sophisticated business user should be able to manage versioning in the DWB with a little training. I'm looking for other options as well if people have any. Once we are successful with this I suspect we may try and build some rule lifecycle management into the workbench itself and contribute it back. But it is a longer term project.

[rules-users] Proto Buf generated code and KIE
We are starting to take a look at using the KIE workbench to expose some decision tables to our users. The original idea is to use generated java from a proto buffer schema as the model. I've got the jar building and imported into KIE. The challenge I'm running into is that the proto buff java doesn't contain the member definitions in a way that the KIE can see them. So I get all of the classes but can't access the actual data elemetns. Has anybody tried this? Or know of a way to take a proto schema (or generated code) and import it as the model for KIE?

The exception below is one of thousands like it. The problem is that the

the type. This rule works fine with strict mode off in 5.0.1 and 5.2.
The rule is:

Re: [rules-users] Disabling strict mode in 5.4
Sorry about that. Here is the base rule:
rule PEL_CHANGELIST_RES.AUTH.Actual Person Base
when
$in : Map($merged : this['MERGED_EPISODE'] != null, $existing :
this['REFERENCE_EPISODE'] != null, $changeList :
this['AUTH_CHANGELIST'] != null)
not(String(this ==
EncounterConsts.Episode.PersonRole.Person.path) from $changeList)
DalMap($existingPersonRoles : this['EPISODE.PERSON_ROLE'] !=
null) from $existing
DalMap(this[EncounterConsts.PersonRole.RoleType] == 1,
$existingPersons : this['PERSON_ROLE.PERSON'] != null) from
$existingPersonRoles
DalMap($mergedPersonRoles : this['EPISODE.PERSON_ROLE'] != null)
from $merged
DalMap(this[EncounterConsts.PersonRole.RoleType] == 1,
$mergedPersons : this['PERSON_ROLE.PERSON'] != null) from
$mergedPersonRoles
$existingPerson : DalMap() from $existingPersons
$mergedPerson : DalMap() from $mergedPersons
then
end
And here is the original again:
rule PEL_CHANGELIST_RES.AUTH.Actual First Name extends
PEL_CHANGELIST_RES.AUTH.Actual Person Base
when
DalMap($existingValue : this['PERSON.FirstName'] != null) from
$existingPerson
DalMap($mergedValue : this['PERSON.FirstName'] != null) from
$mergedPerson
$lowerExisting : String() from $existingValue.toLowerCase()
String(this != $lowerExisting) from $mergedValue.toLowerCase()
then
$changeList.add(EncounterConsts.Episode.PersonRole.Person.path);
update($in);
end
In terms of your why not there is no reason not to structure it your
way other than I have lots of rules structured this way that I would
rather not re-write. If it helps in terms of getting strict mode
disabled I can find a more semantically pleasing example. The heart of
the problem is that you cannot interact with data that comes from a Map
with strict mode turned on.

[rules-users] Rulebase locking
We have encountered a problem with a lock getting generated on an AbstractRuleBase and then never released causing new threads to not be able to execute in that RuleBase. We are on an older version 5.0.1 of Drools and are working on creating a unit test that we can use to see if the defect exists in newer releases. That said, any tips that somebody might have to reproduce a concurrency issue related to rule bases used across threads would be very helpful. Or if there are other similar JIRA entries that we can look at that? This occurs only when the system is under relatively high load and there potentially could be 100 threads attempting to access and use the same rulebase. This is very similar to this JIRA: https://issues.jboss.org/browse/JBRULES-2086?page=com.atlassian.jira.plu gin.system.issuetabpanels:all-tabpanel We have confirmed that we have the fix generated in that ticket.

Re: [rules-users] Condition syntax to access Map
I'm 100% with Edson on this one. Requiring explicit syntax, whether via null checks or .?, can have a big impact on the clarity and level of declarativeness (word?) of a given ruleset. It also makes it a great deal harder to develop DSLs and systems to put rules into the hands of non-developers because then you're requiring those users to bring with them the imperative programming mindset of checking every data point before using it. I think that Edson's example of making the whole expression false if any object on the call stack is null independent of the value is an excellent convention.

When using rules, contrary to imperative code, what we are doing is pattern matching. X( a.b.c == value ) In the above case, we are looking for Xs that make that whole constraint true (i.e. match). If a or b are null, the whole expression will be false, does not matter the value of c or the value it is being compared against. Raising a null pointer exception, IMO, brings no advantage at all to the table... on the contrary, makes writing rules more difficult. Another example we had in the past: class Circle implements Shape class Square implements Shape rule X when Circle() from $shapes ... In the above example, $shapes is a list and the rule is clearly looking for Circles. If there are Squares in there, they will just not match. Raising a ClassCastException like it would happen in an imperative language brings no advantage to the table, IMO. So, IMO, all property navigation should be null pointer safe in the LHS of the rules. This is not what happens today, but I think it should be fixed. Edson 2011/7/28 Vincent LEGENDRE vincent.legen...@eurodecision.com Hi all, I agree with W. : NPE should be the default, and null cases behaviour should be planned by programmers. But I am not sure about using a new operator in rules (and do the update in Guvnor ...). Why not using some drools annotations on the getter specifying the behaviour of an eval on a null value returned by this getter ? And may be these annotation could be added to an existing POJO via the declared type syntax (just like event role in fusion) ?

Re: [rules-users] How to the set drools.dialect.mvel.strictusingDrools+Spring?
Nicolas,
Strict mode works in 5.2. If you set drools.dialect.mvel.strict=false as a
system property it will work correctly. If you want to do it all in spring you
can set system properties in your spring config but make sure that the property
is set before the Drools beans are initialized. Setting it via a system
property will only work one time after that it is cached in the confi.

Would be a workaround for now. I'm working on a test for scrict mode in 5.2.
So your RHS would be something like:
actuator.writeOutput(kcontext, (MyObj)hashMap.get($event.userId));

Can you paste the rule that is failing? I'll see if I can create a unit test in
drools to see if we can reproduce it and open a Jira for it.

Thx for the answer, but I have tried the line you recommended and it is not
working.
My rules tests used to work on drools 5.1.1 but now in drools 5.2.0.GR1 they
don't.
The error that appears when in run the test is this:
[Error: unable to resolve method using strict-mode: ...

this actuator is global variable and writeOutput method is call in the RHS.

Re: [rules-users] large rulebase load time
Hey Edson, Right now we use only one builder and we add one large file. In the past we used multiple builders and files but using a single builder with one large file is much faster. I will have to gather the timing for the differences for the package call versus adding to the kbase. Right now we only collect the combined time. We are still on an older version but are upgrading now to 5.2. I'll let you know if the new API helps. I'll give trunk a shot but I won't be able to use it because we are targeting having this large rulebase in production in mid-February. For reference our current largest production rulebase is ~76,000 rules. Those rules take around 7 minutes to add to the package and the rulebase in a JVM with 2GB of allocated heap.

RE: [rules-users] foreach in drl file
Phil,
Take a look at the manual and look for the forall LHS conditional element if
you can pass all of your objects individually. Or if you must pass your items
into WM as a List then take a look at the collect LHS element examples.
In your example if you wanted to say All Golfers have red pants it would look
something like
import com.sample.Golfer;
import java.util.List;
import java.util.ArrayList;
rule test
when
$list : List() //--The list you use insert into working memory
ArrayList( size == $list.size) from collect (Golfer(pantsColor==red)
from $list)
then
System.out.println(HIT);
End
I didn't run it but you get the idea.
Joe

RE: [rules-users] DRL package builder or rule base error
Vanshi,
In general it would be better to put all of the rules together in the
same drl file as they all relate to the same object and are all destined
for the same rule base. Though there is nothing fundamentally incorrect
about your approach in most cases you want related rules to managed and
deployed together.
As for your exception it is impossible to say without seeing your rules
and the exception. You can try sending them to the list and maybe
somebody will be able to help you.

Hi all,
I have some set of rules which work on same Person object but depending
on
whether a person is student/employee/Faculty, the rule will have
dfferent
logic.
So, I've made 3 .drl files, one will have all the rules for students,
other
for employee and then last .drl for faculty. All 3 .drl have same
package
name (as the first statement in drl) but all rules are named
differently.
When my rule engine starts, it reads these 3 drl files and adds them to
a
single rule base, starts a new session, inserts person in working memory
and
fires rules.
Now, my questions are...is there anything odd/wrong with this approach?
Secondly, I had some rules names same in different drl and when I
changed
them then I started getting null pointer exception error. during
parsing of drl files. Any idea why is that?
code snippet:
list=new ArrayListFile();
list.add(new File(students.drl));
list.add(new File(emloyee.drl);
list.add(new File(faculty.drl));
IteratorFile it = list.iterator();
ruleBase = RuleBaseFactory.newRuleBase();
builder = new PackageBuilder();

while(it.hasNext())
{
source = new

builder.addPackageFromDrl(source);
//if DRL has errors don't add it to the RuleBase
if(builder.hasErrors())
log4j.logError(RuleEngine.class,
builder.getErrors().toString());

ruleBase.addPackage(builder.getPackage());
}

RE: [rules-users] no-loop usage question
You need no-loop on the rules because of the call to modify(s) .
Modify changes the fact in working memory and the engine is
automatically notified of the changes at the end of the modify block.
After modify the same rule could hit again as the conditions are still
true.
The first rule doesn't need the no-loop it because of the check

Not really relevant to the post, but I figured I would mention it, I
have been following this post and updating it to use the current version
of Drools.
http://www.onjava.com/pub/a/onjava/2005/08/03/drools.html?page=7
I have written my rules as such:
package org.drools.examples
import org.drools.examples.StockOffer;
rule PriceBelow100
dialect java
when
s: StockOffer( stockPrice 100 recommendPurchase == null )
then
modify( s ) {
setRecommendPurchase(StockOffer.YES)
}
end
rule NegativeStockPrice
dialect java
no-loop true
when
s: StockOffer( stockPrice 0 )
then
modify( s ) {
setRecommendPurchase(StockOffer.NO)
}
end
rule DontBuyXYZStock
dialect java
no-loop true
when
s: StockOffer(stockName == XYZ stockPrice 10 )
then
modify( s ) {
setRecommendPurchase(StockOffer.YES)
}
end
rule BuyXYZStock
dialect java
no-loop true
when
s: StockOffer(stockName == XYZ stockPrice 10 )
then
modify( s ) {
setRecommendPurchase(StockOffer.NO)
}
end
My question is, why do I have to put no-loop on every rule (except for
the first). After the first time through the rules, it shouldn't be
modifying to where the rules would fire it again. Am I doing something
wrong with how my rules are written? My sample data is this:

Subject: Re: [rules-users] no-loop usage question
I think I follow you now. If I was a little smarter with my conditional
statements to NOT keep assigning YES to something that is already set to
YES then it would probably eliminate the loop. In other words if I added
more checks like the ==null that you pointed out, I could (although I am
not sure that they are bad) remove the no-loop settings. Right?
Thanks,

You need no-loop on the rules because of the call to modify(s) .
Modify changes the fact in working memory and the engine is
automatically notified of the changes at the end of the modify block.
After modify the same rule could hit again as the conditions are still
true.
The first rule doesn't need the no-loop it because of the check

Subject: [rules-users] no-loop usage question
I have been reading through the documentation and trying some of the
tutorials and have a question about the no-loop attribute.
Not really relevant to the post, but I figured I would mention it, I
have been following this post and updating it to use the current version
of Drools.
http://www.onjava.com/pub/a/onjava/2005/08/03/drools.html?page=7
I have written my rules as such:
package org.drools.examples
import org.drools.examples.StockOffer;
rule PriceBelow100
dialect java
when
s: StockOffer( stockPrice 100 recommendPurchase == null )
then
modify( s ) {
setRecommendPurchase(StockOffer.YES)
}
end
rule NegativeStockPrice
dialect java
no-loop true
when
s: StockOffer( stockPrice 0 )
then
modify( s ) {
setRecommendPurchase(StockOffer.NO)
}
end
rule DontBuyXYZStock
dialect java
no-loop true
when
s: StockOffer(stockName == XYZ stockPrice 10 )
then
modify( s ) {
setRecommendPurchase(StockOffer.YES)
}
end
rule BuyXYZStock
dialect java
no-loop true
when
s: StockOffer(stockName == XYZ stockPrice 10 )
then
modify( s ) {
setRecommendPurchase(StockOffer.NO)
}
end
My question is, why do I have to put no-loop on every rule (except for
the first). After the first time through the rules, it shouldn't be
modifying to where the rules would fire it again. Am I doing something
wrong with how my rules are written? My sample data is this:
package org.drools.examples;
import org.drools.examples.BusinessLayer;
import org.drools.examples.StockOffer;
import junit.framework.TestCase;
/*
* JUnit test for the business rules in the
* application.
*
* This also acts a 'simulator' for the business

RE: [rules-users] Deploy rules to JBoss server
I agree with Michael that web apps lib is the best scenario. We provision ours in an ear directly. I should qualify that though in that we use a third party project along with Drools and Jboss that leads us to put other jars in an ear.

[rules-users] Perm gen addPackageFromDrl
HI all, We've got an application that has the need to deploy dynamically generated drl periodically. The drl is regenerated from a set of database tables whenever a change is made to the tables.

I get the error in both 4.0.4 and in the 5.0 versions of drools. In the 4.0.4 version shadow facts are disabled on the rule base. Is regenerating rules frequently from a drl format a valid use case?

[rules-users] Order of operations
I have a question regarding order of operations in the consequence of a rule when using the mvel dialect. When executed the Drl below provides Right =30.0 and Wrong =140.0. The only difference is the parens around the multiplying expressions, which shouldn't be necessary given order of operations. Is this a problem with the drools/mvel interaction or is it completely an issue with mvel? Is the general expectation that all expressions must be completely scoped by parens when using mvel? package test; dialect mvel rule test 11 when then double rightVal=((10-5)*2) + (5*(8-4)); double wrongVal=(10-5)*2 + 5*(8-4); System.out.println(Right =+rightVal); System.out.println(Wrong =+wrongVal); End After execution: Right =30.0 Wrong =140.0 Thank you for all of your help. We are using drools 4.0.4. Joe Also, I haven't figured out how it arrives at 140. The following format also produces 140, which seems a little more strange. double wrongVal=10-5*2 + 5*8-4; ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
RE: [rules-users] Order of operations
Another bug that I just came across while working on getting my parens to work involved not handling scoped numbers properly. Similar to the previous one, but different in that it ends the expression evaluation prematurely. See the drl and result below: package test; dialect mvel rule test 12 when then double rightVal=(10 + 12); double wrongVal=(10) + (12); double wrongValTwo = ((10)+12) System.out.println(Right +rightVal); System.out.println(Wrong +wrongVal); System.out.println(WrongTwo +wrongValTwo); End Results in: Right 22.0 Wrong 10.0 WrongTwo 10.0 Thanks, Joe From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Edson Tirelli Sent: Wednesday, April 09, 2008 12:39 PM To: Rules Users List Subject: Re: [rules-users] Order of operations Hi Joe, It seems someone skipped the elementary math lessons at school... :( Will open a JIRA for that.

[rules-users] DRL Compilation exception
We have a rule package with a target platform of a JBoss server. Based on the recommendation at http://wiki.jboss.org/wiki/Wiki.jsp?page=RulesTomcat we changed the package config to use the JavaDialectConfiguration.JANINO compiler. However, when trying to load the package with the janino compiler we get the stack trace included below. The rules load correctly if the compiler change is not set (but they won't load in JBoss if we don't make the compiler change). Is there an alternative workaround for the JDT issue that would allow us to use something other than the janino compiler to load the rules inside of JBoss? Or is there a known cause or workaround for the exception below? We are using Drools 4.0.4 and JBoss 4.0.5 Thanks for your help Joe java.lang.RuntimeException: SNO: Conversion failed at org.codehaus.janino.UnitCompiler.binaryNumericPromotion(UnitCompiler.jav a) at org.codehaus.janino.UnitCompiler.compileArithmeticOperation(UnitCompiler .java) at org.codehaus.janino.UnitCompiler.compileGet2(UnitCompiler.java) at org.codehaus.janino.UnitCompiler.access$39(UnitCompiler.java) at org.codehaus.janino.UnitCompiler$7.visitBinaryOperation(UnitCompiler.jav a) at org.codehaus.janino.Java$BinaryOperation.accept(Java.java) at org.codehaus.janino.UnitCompiler.compileGet(UnitCompiler.java) at org.codehaus.janino.UnitCompiler.compileGetValue(UnitCompiler.java) at org.codehaus.janino.UnitCompiler.compile2(UnitCompiler.java) at org.codehaus.janino.UnitCompiler.access$12(UnitCompiler.java) at org.codehaus.janino.UnitCompiler$2.visitLocalVariableDeclarationStatemen t(UnitCompiler.java) at org.codehaus.janino.Java$LocalVariableDeclarationStatement.accept(Java.j ava) at org.codehaus.janino.UnitCompiler.compile(UnitCompiler.java) at org.codehaus.janino.UnitCompiler.compile2(UnitCompiler.java) at org.codehaus.janino.UnitCompiler.access$3(UnitCompiler.java) at org.codehaus.janino.UnitCompiler$2.visitBlock(UnitCompiler.java) at org.codehaus.janino.Java$Block.accept(Java.java) at org.codehaus.janino.UnitCompiler.compile(UnitCompiler.java) at org.codehaus.janino.UnitCompiler.compile(UnitCompiler.java) at org.codehaus.janino.UnitCompiler.compile2(UnitCompiler.java) at org.codehaus.janino.UnitCompiler.compile2(UnitCompiler.java) at org.codehaus.janino.UnitCompiler$1.visitPackageMemberClassDeclaration(Un itCompiler.java) at org.codehaus.janino.Java$PackageMemberClassDeclaration.accept(Java.java) at org.codehaus.janino.UnitCompiler.compile(UnitCompiler.java) at org.codehaus.janino.UnitCompiler.compileUnit(UnitCompiler.java) at org.codehaus.janino.Compiler.compile(Compiler.java) at org.drools.commons.jci.compilers.JaninoJavaCompiler.compile(JaninoJavaCo mpiler.java:174) at org.drools.commons.jci.compilers.AbstractJavaCompiler.compile(AbstractJa vaCompiler.java:51) at org.drools.rule.builder.dialect.java.JavaDialect.compileAll(JavaDialect. java:332) at org.drools.compiler.DialectRegistry.compileAll(DialectRegistry.java:60) at org.drools.compiler.PackageBuilder.addPackage(PackageBuilder.java:308) at org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java :167) at com.sample.DroolsTest.readRule(DroolsTest.java:63) at com.sample.DroolsTest.main(DroolsTest.java:24) ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
