Hello Mark,
Yes it does. Unfortunately, the jar names do not indicate which
version they're using. Also, their examples use Drools to assist in
page navigation, and I'm trying to do something different. Any ideas
what might cause this other than missing jars in the classpath? I'm
more than willing to run this down, I was just hoping for some
suggestions to point me in the right direction.
Thanks.

Doesn't Seam have it's over version of Drools, maybe thats on a

I'm using Seam 2.0.0.CR2, Drool 4.0.3, and JBoss AS 4.2.1 along
with all of the relevant support jars.
I have a Java Application that uses the JBoss server for entity
beans, etc. It uses Drools PackageBuilder, loads the drl file and
fires the rules without any problems.
I'm now moving that same functionality to a stateful Seam bean.
When a user clicks on a button, I invoke an action which executes
the same code as in the stand alone java application. However,
when it attempts to create a new PackageBuilder via new
PackageBuilder() it throws:
18:05:18,610 ERROR [STDERR] org.drools.RuntimeDroolsException:
Unable to load dialect
'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java'
followed by:
18:05:18,621 ERROR [STDERR] Caused by:
java.lang.ClassCastException:
org.drools.rule.builder.dialect.java.JavaDialectConfiguration
18:05:18,621 ERROR [STDERR] at
org
.drools
.compiler
.PackageBuilderConfiguration
.addDialect(PackageBuilderConfiguration.java:147)
I've seen this posted several times, and the suggested cause is
missing jars in the classpath. However, I have all of the 4.0.3
Drools jars, mvel14, and jdt-core jars in place.
Obviously, it's some configuration problem since I have the exact
thing working as a java application.
Any suggestions?
Thanks.
