Unable to build index of kmodule.xml from Kie project jar
by Sumit Dhaniya
I'm trying to use the Kie jar in my spring project. It successfully
identifies the Kie jars in my project but give errors listed below :-
INFO ClasspathKieProject - Found kmodule:

Even if I define kie modules and sessions in my conf file I can't access the
drl and rdrl files in my Kie Project.
Though if I create my objects using
kieServices.getResources().newUrlResource(url); everything works fine.

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);

I have follow the instructions provided from this link:http://drools.46999.n3.nabble.com/rules-users-Problems-deploying-war...
1. I have added these 3 jar files in my tomcat_home/lib directory
a. javax.security.jacc-api-1.5.jar
b. kie-tomcat-integration-6.1.0.CR2.jar
c. slf4j-api-1.7.7.jar
2. Modified the server.xml in tomcat_home/conf directory by adding the line below in the <Host> tag
<Valve className="org.kie.integration.tomcat.JACCValve" /> 3. Added the following in tomcat-users.xml
<role rolename="admin"/>
<role rolename="analyst"/>
<role rolename="manager-gui"/>
<role rolename="user"/>
<user username="admin" password="dummy" roles="admin"/>
<user username="tomcat" password="dummy2" roles="manager-gui"/> 4. Delete org.uberfire.security.auth.AuthenticationSource inside WEB-INF/classes/META-INF/services 5. Rename org.uberfire.security.auth.AuthenticationSource-TOMCAT-JEE-SECURITY to org.uberfire.security.auth.AuthenticationSource inside WEB-INF/classes/META-INF/services 6. Created a setenv.sh in tomcat_home/bin directory, which has this as it content
export JAVA_OPTS="-Dfile.encoding=UTF-8 -Xms128m -Xmx1024m -XX:PermSize=64m -XX:MaxPermSize=256m"
7. Finally, uncomment the section in web.xml from the WAR file.
I am using Tomcat 7.0.54 and running on 64 bit Linux server. I would appreciate any suggestions.

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?

Drools Applications Google Group
by Mark Proctor
A while back there was a discussion on the volume of posts and the range of post discussions. OptaPlanner already has it’s own google group, which has helped reduce the volume. There is still the discussion on whether to split Drools.
My initial idea is to leave this list for installation, setup, configuration, deployment and getting started (hello world won’t run) - this tends to be a fairly shallow knowledge area, that new people will need to deal with. Then also create a separate google group for those wanting help on writing rule applications, that’s authoring (drl, score cards, decision tables etc) and running (insert, fireAllRules etc); this would become a deep knowledge area. In the google group you would not ask how to install the workbench, or how to deploy your app, or how to setup HA etc.
Thoughts?
We are about to do 6.1 final. For this we are revamping the websites, and sorting out our communications (lists etc) at the same time.
