This is specified in the drools-core jar, in the

OK, done: https://jira.jboss.org/browse/JBRULES-2818
There's any reason for packing drools-process-task with persistence.xml? The
problem is that Jboss will try to deploy it if it's in the classpath.
Thanks.

Hi guys,
I'm trying to deploy a spring based Knowledege Session with JPA persistence
on Jboss 5.1, I was able to do it using a RESOURCE_LOCAL persistence unit
but I would like to use a container JTA based deployment.
Basically, JPAConfiguration requires a Spring PlatformTransactionManager
then I tried to use the following combination:
<bean id="springTxManager"
class="org.springframework.transaction.jta.JtaTransactionManager" />
<jee:jndi-lookup id="springEMF" jndi-name="java:DroolsEMF"/>
The problem is that using it,
SingleSessionCommandService.initTransactionManager does not create a
JPAManager.
So, my guess for this to work is to add support for this on
SingleSessionCommandService or change JPAConfiguration
(drools-spring-1.0.0.xsd) to accept that no transaction-manager is defined,
causing Drools JtaTransactionManager to lookup the TransactionMananger from
JNDI context.
The only way that I could deploy it is using these beans definitions:
<bean id="springEMF"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceXmlLocation"
value="classpath:META-INF/spring-persistence.xml" />
<property name="jpaVendorAdapter">
<bean
class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
</property>
</bean>
<bean id="springTxManager"
class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="springEMF" />
</bean>
Thanks.

This should have been fixed in revision 35785 on trunk. So try a
snapshot version, it should not ask for authentication anymore if you
have configured Guvnor to bypass login. Details please see jira:
http://jira.jboss.org/browse/GUVNOR-802

Hi there,
We are evaluating Drools for an industry project. Trouble is, I'm not
good at ignoring men behind curtains, and need to know how things
actually work.
Links to papers explaining the theory and principles of Drools Expert
are highly appreciated.
Some specifics:
We have a network of domain objects, with basic attributes (numbers,
strings, enums) and two-way mapped associations.
Rules modify the basic attributes only. Associations (references and
reference sets) are static.
"where" conditions refer to both static information and modifiable attributes.
I was wondering how I can express this distinction in my domain
objects without sacrificing readability of the actual rules?
(Domain experts should be able to edit the rules themselves.)
Here's the current pattern of my rules:
rule "child molester"
where
$parent : Parent( ... )
$child: Child(parent==$parent ... attribute!="value")
then
modify ($child) { setAttribute("value") }
end
I'm not happy my users need to know about the setter methods instead
of using the same reflection-backed notation as in the condition.
I also worry they'll make infinite loops by omitting the
"attribute!=value" clause.
So I guess I should elevate the attributes to first class status in my
model to make them the atomic unit of triggering, but how do I do that
elegantly?
rule "attribute molester"
where
$parent : Parent( ... )
$attribute : StringHolder(get()!="value")
$child: Child(parent==$parent ... attribute=$attribute)
then
modify ($attribute) { set("value") }
end
That looks worse than before! Please share your thoughts.
Thanks in advance:
Gabor Szokoli
