KnowledgeAgent exception
by Claus Straube
Hi all,
I'm trying to use the resource scanner in my application (drools 5.1.1,
also tried in 5.2.0-SNAPSHOT):
--snip--
//resource scanner
KnowledgeAgent kagent =
KnowledgeAgentFactory.newKnowledgeAgent( "MyAgent" );
kagent.applyChangeSet(
ResourceFactory.newByteArrayResource(this.getChangeConfiguration()) );
KnowledgeBase kbase = kagent.getKnowledgeBase();
this.ksession = kbase.newStatefulKnowledgeSession();
--snip--
and getting always a 'KnowledgeAgent exception while trying to
deserialize KnowledgeDefinitionsPackage' (see stacktrace below). Of
course I've googled for the problem and found that it was in 5.0.1 a
incompatibility problem between drools expert and guvner. But I'm not
using guvnor at all. I want to place some *.drl files in a directory and
run an agent that automatically updates my knowledge base. The agent
finds the directory and the files, but has problems to deserialize them.
If I'm loading them directly into the knowledge base they will work fine.
Any hints to find a solution are welcome.
Best regards - Claus

Fwd: Upload POJO Model
by Michael Anstis
---------- Forwarded message ----------
From: <ptazbaz(a)yahoo.com>

Subject: Upload POJO Model
Hi,
It sounds like you know Drools fairly well and I wanted to confirm if upon
uploading the POJO model, one could edit via the Guvnor to add new
objects\attributes. We want to start by uploading a POJO model into the
Guvnor, but let business analysts add new attributes to the existing objects
via the wizards in the Guvnor. These jar files seem locked down once
uploaded and cannot be edited by general users. Any thoughts? Thanks in
advance.

Guvnor error after creating data
by thuffman00＠aol.com
I'm having a problem with Guvnor after I create a single category, package, and rule. After completion, I logout and attempt to reenter the GUI but get an error box instead of the login prompt. The error has no data associated with ti and there are no exceptions in the log nor on the jboss console. At first I thought this was due to the version I was using ( from jboss,org and not jboss.com). I've since downloaded the dotcom version of BRMS standalone and still having the same problem. Another factor is that I'm attempting to use PostgreSQL 8.04 instead of Derby. The version of Java is 1.6 and I tried upgrading Jackrabbit from 2.1.0 to 2.2.1 with no help. The environment is Ubuntu 10.04. Both the Workspace and Version in the repository.xml use the same DB with different schemaObjectPrefix. Here's an example:
<PersistenceManager class="org.apache.jackrabbit.core.persistence.bundle.PostgreSQLPersistenceManager">
<param name="url" value="jdbc:postgresql://localhost:5432/Guvnor"/>
<param name="user" value="postgres"/>
<param name="password" value="XXXXXX"/>
<param name="driver" value="org.postgresql.Driver"/>
<param name="schema" value="postgresql" />
<!--<param name="schemaCheckEnabled" value="false"/>-->
<!-- <param name="copyWhenReading" value="true"/> -->
<param name="schemaObjectPrefix" value="version_" />
</PersistenceManager>
Has anyone else come across this?
TIA

Guvnor - Limitation for number of classes or fields?
by Dean Whisnant
My class model contains in the neighborhood of 2,400 fields which we have broken down into the imported classes below. The breakdown is based upon repeatable loops within an EDI transaction. This allows our users to first select the LOOP (or class from below) and then choose from a smaller number of fields when building their rules.
When creating a rule in Guvnor, the WHEN class/field choosers work very quickly. But then when you do the THEN side, a message pops up saying that A Script on the page is causing the web browser to run slowly. You have to answer NO to this question approximately 3 times before it then brings up the "add new action" dialog. The field chooser then works fine, though you get the script message again when you go to add another action.
Is there a limitation to Guvnor for the number of classes or fields in the model? Is there a memory setting that needs to be configured differently?
Thank you in advance!
Dean

Question on Drools upgrade from 2 to 5
by Steve Floridas
Hi,
We are an insurance company employing drools ( version 2 currently) for
policy validation rules and for reading policy specific rates from
spreadsheet using drools. We are currently running in to memory issues when
we execute the compiled JAR ( including the drools compiled files), as there
are lot of rules fired for different versions of policy rating. My question
here is :-
Is there any scope of resolving this memory issue with upgrade of drools
package from version 2 to version 5? Will the compiled DRLs in Drools 5 be
more compressed compared to Drools 2?
I have been trying to upgrade to Drools 5 by adding the necessary jars for
compilation. But unfortunately I am gettng few errors on spreadsheet and DRL
compilation. Is there more to work on the upgrade?
One of the errors I frequently get for spreadsheet comparison is something
like below:
*Invalid character input "?" (character code 65533)*
Please clarify my above questions.
Thank you much,
Steve
