Re: [rules-users] Drools causes switch(enum e) to break?
by SydneyTechHead
I've reproduced this issue with a simple example:
1. Create a new "Drools Project" in Eclipse Kepler with Drools 6.0.1.Final
installed (JDK 1.7) with simple "Hello World" rule example. Project builds
OK.
2. Create the following new class:
public class EnumTest {
private enum EnumType { On, Off }
private EnumType et = EnumType.On;
public EnumTest() {}
public String TypeText()
{
switch(et)
{
case On:
return "On";
case Off:
return "Off";
default:
return "";
}
}
}
3. Rebuild project. Eclipse reports Problem:
Drools Error: "Cannot switch on a value of type EnumTest.EnumType. Only
convertible int values or enum variables are permitted"
4. Export Ant Build file for the project and run the Ant Build. Build
successful.
5. Create a vanilla Java Project (no Drools) and add the same EnumTest
class. Eclipse project builds OK.
As the project builds OK via Ant, it appears that this is an issue with the
Eclipse incremental builder conflicting with Drools 6. As noted in my
previous post, it appears that Eclipse may be reducing JDK compiler
compliance level down to 1.5 or referencing JRE 1.5 in class path as a
result of this conflict, as I've occasionally noticed it changing these
settings in project properties.
Any ideas or clues why this may be the case and what is the best channel to
report this Eclipse issue?

Trying to load a module from Maven coordinates
by david.berkman
Using Maven 3.2.1 and Drools 6.0.1, I'm trying to simply follow the
instructions for loading a container with a jar at a set of maven
coordinates. I have confirmed that the jar exists at the specified
coordinates (in Nexus), and that I can download it without using a
username/password (just an http get), and that the jar does contain both
.drl files and a /META-INF/kmodule.xml. I'm using the code below, and have
added the extra dependencies listed, but I get the errors shown below all
that. First off, working out the proper dependencies is no mean feat, when
it seems that just kie-ci should be necessary. What a pain, and there is far
too little documentation to help. But, I assume this should be possible, and
maybe some kind person out there has the magic combination of Drools, Maven,
and jars to make it work?
Thanks in advance,
David

Usage of the jcr2vfs migration tool
by dstern
Are there instructions anywhere for using the jcr2vfs migration tool?
I pruned my JCR repository (created under Guvnor 5.6.0.Final) until the
migration tool ran without error (which meant archiving all my brl format
assets among other things) but I'm not sure what to do with the output.
I copied the contents of outputVfs to my existing .niogit folder (leaving
the .niogit generated by the migration tool alone) but the migrated
repository doesn't show up. Is this because I didn't replace my existing
.niogit with the one generated by the tool?

Drools 6.0.1: Pushing changes back to Workbench GIT using SSH
by dotrc
I am using workbench for managing my rules maven projects within the embedded
GIT repository. I am aware that using git:// protocol, I can clone an
existing rule repository; I can do this successfully.
For authoring rules, I want to use Eclipse (using EGit). I want to push my
commits back to the GIT repo. I understand that I'll have to use ssh
protocol instead of git for specifying the repo, something like this:
ssh://{userName}@localhost:8001/{repoName}
When we use a standard GIT repo like stash, it gives us an option to set our
public key on the stash server, but I'm not able to find a way to do that
with the embedded ssh server within workbench. Hence, I'm not able to
authenticate myself and perform a push.
We tried creating a private-public key pair using ssh-keygen and put that
within c:\users\<username>\.ssh and added the public key to
'authorized_keys(2) (though I know this may not be the right place) and then
used the private key as the identity file with ssh client directly from
cygwin, again to no avail.
Any pointers will be really appreciated.
Also, should the username be 'admin' or any other specific one for pushing?
Will the existing Windows username work?
Thanks,
Rishi

Drools 5.6.0.Final PKG vs DRL infinite loop
by gboro54
We are using drools 5.6.0.Final and the same version of Guvnor. When we run
the source file of a package from Guvnor everything works as expected. When
we take the same rules and create a package we get stuck in an infinite loop
of rules firing(I have a listener logging every time a rule is
created/fired). Why would there be a difference if the rules don't change
between the source and the pkg?
We build the kbase as follows:
KnowledgeBuilderConfiguration config = KnowledgeBuilderFactory
.newKnowledgeBuilderConfiguration();
config.setOption(PropertySpecificOption.ALWAYS);
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory
.newKnowledgeBuilder(config);
for (ResourcePair pair : pairs) {
/* kbuilder.add(
ResourceFactory.newClassPathResource("rule-sets/2014/feb/"+pair.resourceName),
ResourceType.getResourceType(pair.resourceType));*/
kbuilder.add(
ResourceFactory.newClassPathResource(pair.resourceName),
ResourceType.getResourceType(pair.resourceType));
}
KnowledgeBuilderErrors errors = kbuilder.getErrors();
if (errors.size() > 0) {
StringBuilder sb = new StringBuilder();
for (KnowledgeBuilderError error : errors) {
sb.append(error + "\n");
System.out.println(sb);
}
throw new IllegalArgumentException("Could not parse knowledge.
\n"
+ sb);
}
this.knowledgeBase = KnowledgeBaseFactory.newKnowledgeBase();
this.knowledgeBase
.addKnowledgePackages(kbuilder.getKnowledgePackages());

by Soumya.plavaga
I am using global slf4j log4j logger as a global variable within our drl and
inserting that global logger value at runtime into kiesession. While we are
trying to do logger.info with multiple arguments then it's giving the
following exception stack trace -
Exception executing consequence for rule "Test Logger 2" in
test.rules.system: java.lang.RuntimeException: cannot invoke method: info

Example: My drl file looks like this -
package test.system.rule;
import test.platform.model.*;
import org.slf4j.Logger;
global Logger logger;
rule "Test Logger 1"
when
then
logger.info("within test logger 1");
end
rule "Test Logger 2"
when
then
logger.info("within test logger 2. Rule fired {}",
drools.getRule().getName());
end
While rules are firing then the first logger is getting printed into console
but second one is not getting printed and giving the above exception to me.

How to read XML using XMLPackageReader-Drools-compiler.5.2.1.final?
by Praveen
Hi,
I am using Drools-compiler.5.2.1.final.
I am trying to convert an drl to xml and vice versa using DrlParser,
DrlDumper, XMLPackageReader and XML Dumper.
Drl to XML conversion works fine but XML to Drl throws NPE.
I have placed the XML file under a folder called sample.
NPE is thrown at line 5..
Also attached is the exception.
Please suggest.
TIA.
Reader source = new InputStreamReader(
DroolsConversionHelper.class.getResourceAsStream(xmlFileName));
PackageBuilderConfiguration conf = new PackageBuilderConfiguration();
XmlPackageReader reader = new
XmlPackageReader(conf.getSemanticModules());
DrlDumper dumper = new DrlDumper();
//line 5 reader.read(source);
PackageDescr descr = reader.getPackageDescr();
String test = dumper.dump(descr);
System.out.println(test);
java.lang.NullPointerException

KieContainer#updateToVersion fails when both versions of a drl file contain an event type declaration for an existing class
by mikedev9000
I am using the latest drools 6.1.0-SNAPSHOT. I have two jars containing
different versions of a KieModule, and they each contain a drl file with an
event type declaration for an existing class. If I try to update the
container from one version to the other, the call to
KieContainer#updateToVersion returns a Results instance that contains errors
related to the @timestamp attribute on that event declaration. Here is an
example of the error message: "[Message [id=1, level=ERROR, path=r0.drl,
line=3, column=0
text=Error creating field accessors for timestamp field 'mytime' for type
'FooEvent']]".
The following .patch file can be used to add a unit test to the
IncrementalCompilationTest.java file that demonstrates this problem.
test_container_update_problem.patch
<http://drools.46999.n3.nabble.com/file/n4030100/test_container_update_pro...>
After applying the patch, and running this unit test, I see the following
test failure:
java.lang.AssertionError: Errors detected on updateToVersion: [Message
[id=1, level=ERROR, path=r0.drl, line=3, column=0
text=Error creating field accessors for timestamp field 'mytime' for type
'FooEvent']]
at org.junit.Assert.fail(Assert.java:88)
at org.junit.Assert.assertTrue(Assert.java:41)
at org.junit.Assert.assertFalse(Assert.java:64)
at
org.drools.compiler.integrationtests.IncrementalCompilationTest.testUpdateWithDeclarationPresent(IncrementalCompilationTest.java:95)
This error makes it nearly impossible for me to rely on and use
KieContainer#updateToVersion, because I need to allow frequent changes to be
made to drl files at run time, and I would prefer not to recreate the
KieContainer, and all of its KieBases and KieSessions on every update.
Is this a known issue? If so, are there plans to fix it before the
6.1.0.Final release?
