Questions regarding Guvnor
by Harshit Bapna
Hello All,
Few questions:
1. What is the release date of Guvnor 5.2 ? (Couldn't find it from the site
of the documentation)
I am interested in the functionality to add the guvnor editors in
another app for rule editing. i.e. StandaloneEditorServlet
2. Which SVN TAG of the Guvnor (which has standalone editor functionality)
should I use ?
Note: On trunk I have observed that the war contains a folder *guvnor* where
as guvnor 5.1 war contained folder *org.drools.guvnor.Guvnor*
Also the web.xml in the trunk has the following url pattern <url-pattern>/*
org.drools.guvnor.Guvnor*/feed/*</url-pattern>
This url pattern would never be matched as the Guvnor.html is under
guvnor/Guvnor.html. To make it work I had to update the url patterns in the
web.xml
Is there anything that I am doing wrong ? (mvn clean install
-Dmaven.test.failure.ignore=true)
IMO, the trunk has partial changes checked in. Hence it is not stable.
Thanks

KnowledgeAgent and applyChangeSet
by bob.breitling
If I have a KnowledgeAgent and I create a URL Resource and set its
basicAuthenication, username and password attributes then I call the agents
applyChangeSet method I get a HTTPD 401 response from the Guvnor. It does
not happen to my resourse which has a valid username and password, but it
happens to the resource in the changeSet xml tag.
It would seem to me that the resources that are built from the resource I
passed would inherit the basicAuthenication, username and password
attributes that I set and know work, but they don't and I get this error.
If I debug the code and filling in those values on the resource passed to
the createPackageFromResource method before the resource stream is read the
code works.
I am using the NilAuthenicator in the Guvnor components.xml and that seems
to be working. I get access to the Guvnor without being asked for
credentials.
I tried to configure my jboss (4.2.0) in login-config.xml to allow access to
everything as guest. But no luck.
Any suggestions?
Bob

OSGi version of Drools
by Flavius Vespasianus
Hello,
is there anywhere a OSGi bundle with Drools 4.0.7? I know about
com.springsource.org.drools.* but these had a lot of additional
dependencies and I wasn't able to get them work.
My problem is that I need to have three projects: one is the basic
library which uses Drools very intensively. The second project is editor
- an Eclipse plugin (that's why I need the OSGi bundle) using some
classes from the basic library. It doesn't use Drools, but there is a
dependency. The third project is classic Java application, also using
the basic library.
The basic library was originally created using standard Drools project
wizard (I have downloaded the Eclipse Drools plugin -
org.drools.eclipse). But when I tried to deploy it as an Eclipse plugin,
it couldn't find the Drools classes.
I found a little workaround - I have compiled the binaries (drools-core,
drools-compiler and from libs the mvel, antlr3 and eclipse-jdt-core)
into separate plugin using "Create a plugin from existing jars" wizard.
But if I add this dependency to the basic library, I get a
NullPointerException error on every dslr file and I cannot run the
application properly). At least the second project (editor) can be compiled.
What am I doing wrong? Or can I find somewhere the binaries compiled
correctly into OSGi bundle?
Thanks a lot!

Drools Expert 5 OSGi
by jflamy
I want to manage Drools Expert rules with Drools Guvnor. My understanding is
that requires the use of Drools Expert version 5.
I also need to use an OSGi-packaged version of Drools Expert.
I saw a forum posting in 2010 alluding to such a beast, but the springsource
forums only provide 4.0.7.
Is there a ready-made OSGi bundle for drools expert 5, or alternately
specific instructions for building one ?

Drools Server 5.1.1 - can't run test.jsp
by OlliSee
Hi there.
I was trying to setup the Drools Server. As I understand, this is not a
server per se, its just the usual Drools with some framework plumbing. But I
appreciate not having to do that myself. But I can't get it to work.
I imported the .war file into my Eclipse and tried to deploy it to a few
application servers, but it didn't work.
I tried Tomcat 6/7, JBoss AS 4.2.2/4.2.3/5.0.1/5.1.0 (I know, they are just
using Tomcat, but I gave it a shot anyway...).
The .war deploys right I guess. But as soon as I try to run the test.jsp, I
get a lot of errors.
The log below is from Tomcat 6,...

Re: [rules-users] Firing Mulitple packages

Could you post the way you are using to add kassets to kbase?

Hi Esteban,
I have tried the same logic by adding all the packages in my application in

other kassets like dsl, ruleflow present in it were not added to the same.
Do we need to add everything separetly?
Kindly let me know whether im missing something here.

Problem with DroolsFlow transaction
by HMandic
I have a problem with transaction manager in drools flow (at least I think
so).
I'm running an EJB3 application in Jboss AS 5.1.0GA with Postgres 8.4.4 as
database. I use one schema for my data and another for drools data. The
application itself is also split in two projects, one for my utility classes
that interact with drools and the other for my application that uses those
utility classes.
I'm using the same datasource and transaction type is JTA.
I have an object that holds a reference to processID from drools flow as one
of its fields. When I invoke my method to create that object (in a stateless
session bean), a transaction is opened and it lasts until the end of said
method. But somewhere inside that method I need to invoke
ksession.startProcess(processName, params) and then I get this:
java.lang.IllegalStateException: Wrong tx on thread: expected
TransactionImple < ac, BasicAction: -3f57ffd6:dfb:4c878d37:7e status:
ActionStatus.ABORTED >, actual null

.
Does that mean that I need to run the drools part in a separate thread?
I'm clueless...
