Kie-Workbench install error
by gboro54
Hi! I am trying to install the Kie-workbench war to a jboss 7 environment and
get the exception below. I would imagine this is because of firewall and my
company will not open a connection to this repo. My question: is there a way
to have the deployment go through without loading the example projects?
Thanks!

Upgrade from drools 5.4 to 6.0.0-Beta3 - Legacy API Adapter JAR
by MaverickDrools
Hi,
There is not enough documentation on drools v6.0.0-Beta3, but this is what
I'm trying to do.
Our system was designed with 5.3 but then we encountered the issue with
synchronization (https://issues.jboss.org/browse/JBRULES-3283), so we
upgraded to v 5.4.
Things worked fine until we multithreaded the client code due to which we
faced another issue (https://issues.jboss.org/browse/JBRULES-3675)
So finally now, I'm trying to upgrade to 6.0.0-Beta3 since both those issues
should've been fixed with 6.0.0-Alpha1. The problem I'm facing is, I do not
have enough documentation to look at to see how to convert those things. I
went through the slides etc that were posted on the mailing list for the
conferences, but I'm still unable to figure it out correctly..
So, can someone point me to a JUnit or something that I can look at to
figure this thing out?
static {
KieServices ks = KieServices.Factory.get();
KieRepository kr = ks.getRepository();
Resource res = ks.getResources().newFileSystemResource(
"src/main/resources/rules/abc.drl");
KieModule kModule = kr.addKieModule(res);
kc = ks.newKieContainer(kModule.getReleaseId());
}
throws an exception on kr.addKieModule(res) which says Error in opening zip
file.. I assume we are now expecting a jar instead of a plain drl file. Is
there a way to convert this drl into a jar that the 6.0 code can understand
(for compatibility purposes with the existing system)?
Another thought was to make use of the Legacy API Adapter JAR, but I
couldn't find any examples of the same. Can you point me to a code
sample/JUnit that could explain how this works?
Thanks

java.lang.NullPointerException when using a custom operator
by Hezi Stern
Hi all,
I have been working with Drools 5.2.0 on windows xp and I have a stable
project.
I upgraded to windows 8, drools 5.5.0 and upgraded to eclipse Juno (from
Helios).
I have now encountered a strange problem with my existing drools project. I
have a accustom operator called supersetof which now results in the
following error reported in the IDE in any file where the supersetOf is used
(LHS):
Error: java.lang.NullPointerException
After receving this error the drools parser does not work, hence this is the
only error I have.
I have tried to use the Drools 5.2.0 again (on the new windows 8 machine)
but I get the same problem so I guess it has to do with some IDE\eclispe
configuration or compatibility issue.
Obviously not the drools project code as I have not made any changes to the
working project.
I did make sure the custom operator is configured similar to the way it was
on my previous computer.
Any ideas? Is there a different configuration for Juno?
Thanks,
Hezi

5.6.0.CR1 gives a NullPointerException in after evaluator
by abr
Hi everyone,
I tried to switch from 5.5.0.Final to 5.6.0.CR1 and got a null pointer
exception in the evaluation of the after evaluator.
(Exact method is:
/org.drools.base.evaluators.AfterEvaluatorDefinition.AfterEvaluator.evaluate(InternalWorkingMemory,
InternalReadAccessor, InternalFactHandle, InternalReadAccessor,
InternalFactHandle)/ )
When debugging, the exception occurs at the very first line of the method,
in:
/ if ( extractor1.isNullValue( workingMemory, handle1.getObject() ) ||
extractor2.isNullValue( workingMemory, handle2.getObject() ) ) {
return false;
}
/
The cause of the exception is that handle1 is null.
The rule where the exception occurs looks like:
/ MyFact(
fromdate before[ 0d ] $min,
( todate == null || todate after[ 0d ] $max ) )
/
When the exception occurs, /MyFact.fromdate/ is not null, /$min/ is not
null, /MyFact.todate/ is null, /$max/ is not null.
In AfterEvaluator.evaluate : /extractor1/ refers to /MyFact.todate/,
/extractor2/ refers to /$max/, /handle1/ is null, /handle2/ refers to the
fact including the attribute to which /$max/ variable is bound to.
Of course, this worked fine in 5.5.0.Final.
I couldn't test this out in Drools 6.0.0.CR5 because I have dependencies to
drools-spring JAR that does not exist anymore in 6.0.0.CR5.
Is it simple to fix this problem?
Thanks in advance.
Best,
Alexis

Incorrect resolution of global symbols in LHS rule constraint (Java dialect)
by mikerod
I upgraded from 5.5.0.Final of Drools (rule engine) to 5.6.0.Final and I am
now seeing errors with globals.
We have rule constraints that access globals in a DRL; like this:
some.classpath.package2.MyType ( global_instance.invoke(this) == true )
I have `some.classpath.package.SomeType global_instance;` declared at the
top of the DRL, but it doesn't seem to be interpeting it as a global in the
rule's restriction.
So, putting this into context within, I have a DRL such as:
package my.package.example;
global some.classpath.package.SomeType global_instance;
****
rule "Example rule"
when
some.classpath.package2.MyType ( global_instance.invoke(this) == true )
then
// do something
end
****
I am getting an error from the package builder originating from the "Example
rule" specifying something like:
"can't find method MyType.global_instance()"
Once, again this did work in 5.5.0.Final, but in 5.6.0.Final I am getting a
failure trying to build the knowledge package.
It looks to me like the `global_instance` symbol is not being recognized as
a global in the DRL and is trying to be
resolved as a method of the MyType class.
So I guess it would be trying to do a
"MyType.global_instance().invoke(this)" or something.
The intent is that `global_instance` will be set for a session with an
immutable function-type of class
(invoke is an instance method though; not static). The rule restriction
uses this function/predicate to determine if some
complex criteria is true for `this` MyType instance.
I would appreciate any insight into what the issue might be. I haven't been
able to find any threads out there on a similar issue.
