hi,
i've created a simple project that fails/succeeds base on the passed
transaction manager. See my comments in the test.

Hi Dan, did you manage to get it working?
I didn't have time to look at your problem yet. I'm having very complicated
times, but I'm looking forward to have at least one day to fix that issue.
Can you update me your situation right now?

@Wolfgang, maybe I need to update the documentation to explicitly inform
about this behavior :). The agent doesn't make anything special to sync the
sessions with the kbase. If you add a rule by hand to an existing kbase, all
the session from this kbase will automatically detect the changes.

Hi Mike,
thanks for the information. No, I didn't know the Expert documentation.

As far as I remember, there was a problem with spring and JTA XA
implementation.
Can you provide us a simple test case that fails? we can create a jira issue
and work on it easily if we have that.
Greetings.

@Wolfgang: if you are using drools.agent.newInstance=true (the default

explicitly force the agent to do so, or because a monitored resource

hi,
i've been trying to setup my drools flow persistence layer to use spring
transaction management (JTA) but it looks like some parts of the code are
missing in 5.1.1 rendering the whole idea impossible.
Whats happening is that when my transaction manager calls commit it gets

...I forgot the mention that I've made sure that all files are on the
classpath. If I go directly for the drl file without using KnowledgeAgent
and ChangeSet.xml it works.

Hi, again!
the problem was that I didn't actually ever use the
KnowledgeAgentConfiguration... so no wonder it didn't work...
But now I have another problem that I just can't get my head around instead.
this is the ChangeSet.xml I'm using:
And it works just fine. But if I re
Hi,
Guvnor is an authoring and repository environment not a runtime environment.
Please read about KnowledgeBuilder and its related "addResource" methods
together with the ResourceType.PKG. You can also look at using
KnowledgeAgent but for now an understanding of KnowledgeBuilder will
suffice. I
Hi all,
I am new in Guvnor and have a lot of questions.
I have created a decision table with the Guvnor web app. I have also
created some test. All seems to be fine.
Now I want to use the rules in a web application. Unfortunately Guvnor
doesn't provide a web service interface so I must develop
I believe that you can only import one class with the same name,
regardless of package. To access the other class within your code, you
will need to refer to it every time with the fully qualified class name.
This conforms to the behavior of Java source files.

Hi,
We have scenario in which the imported java classes have same name but
different package.
The drools guvnor is throwing compilation error stating that import
statements are colliding, even though the java class packages are different.
Please let me know if there are any solutions for this i

ok thanks, i think i confused my notion of eval() with also its ability to
return int on calculations in some other framework.
The reason why i started this thread was to ensure in the process of Rule

It would help if you read the documentation which explains that eval() must
return a boolean.
"Predicate" is a mathematical concept; how it is implemented in some system
is a technical issue. That said, "predicates" can be expressed in Drools one
way or other, and some predicates may be more effic
I believe eval() solves that purpose functionally but is not optimal; not
sure how evals() tie in with Rete-OO
Specially since the return type of eval() is not known, I can seriously
doubt it being optimal as using Objects directly in conditions.

I thought wrapping a method in a eval statement is effectively allowing you to
use methods directly, it is syntactic sugar to say this is a method call,
evaluate it and then use the result in the rete graph.

Boban,
Instead of using an explicit JDBC connection string, you can instead find
your MySQL connection via a JNDI lookup, externalizing your database
connection information to your application server. You'll have to Google
the exact details, but I believe you set the driver class to
