Hi,
Does anyone have a working Hibernate + Bitronix + Tomcat configuration
which works with Drools process persistence ?
If so can you share it?
In my case Hibernate just does not find the Datasource, no matter what I do.
Thanks

This is strange. Could you isolate this behavior in a unit test?

I believe I tried this and having multiple package statements - even for the
same package - in a file generates a different error.
However, the example does list the package as optional - which if it were
would also work. Thanks!

Well, I just wrote a sub
DSL uses regular expression parsing, but the LHS is recursive. (Chomsky
type-3 vs. type-2, if you want the comp. sci. background.) This means that
using DSL restricts you to a subset of the LHS language, although you may
map arbitrarily complex LHS expressions to a single DSL sentence. (In your

You can't be much worse off if you add "package foo" to the template.
Or is there a problem with this obvious workaround?

Thx for your answer, Wolfgang.
To be honest, when I first ran into this, I was in doubt whether that is a
parsing error in Drools (or mvel)? Or is an error that I got into because of
how I constructed the DSL expression?
It seems that it is an error in Drools and I wonder if that should be repo
Hi,
Is there anyway we can rewind the drools flow? I mean I save my flow in db
and at a later stage I want to rewind it and start it from some other node
instead of the one it was paused at. Has anyone tried this kind of thing
before?
I've got Human Tasks in my flow and my flow stops at one of t

Ah! Gotcha. Yep, classpath. I developed this resource adapter for

Thx for your answer, Wolfgang.
While your advice makes sense, it does not help me. I cannot avoid using OR. I
use Drools for validation and I have some cases when I need to use OR between
conditions for evaluating an invalid state. Also, the solution you proposed
works fine when the rule works

Hi,
I have implemented the requested feature. Please try to check if the
solution works for you so I can close the issue.
For further information about the usage of this feature, please take a look
at the comment I have added in the jira issue.
Best,

I am trying to incorporate several templates in a single output drl file.
According to the 5.0.1 docs "package" is optional:
Example 5.3. Rule template file: templates
template header
parameter-name-1
...
parameter-name-n
package ... # optional
However, it seems that the drools parser uses "pac

That was a contribution from a community user a long time ago whose
purpose is only to group the statements per "object" on the tooling, like
the guided editor. It has no runtime semantics.

Yes you do need transaction management.
How is your datasource configured in hibernate?
Are you using jndi?
This may help:

The bit you want is this:
You just have to create a jndi.properties file in your classpath with this
content:

Hi,
I am trying to do Drools persistence in Tomcat with Hibernate, but it
would seem it also requires transaction management. Is that true?
In the meantime I tried to setup Bittronix to provide the transaction
management, but I can't get Hibernate to find the datasource at all.
I ve followed the
We were faced with the same issue. Eventually, I realized that we did not

down the use of the rules engine into smaller logical chunks. I now have a

A DSL definition may have an "Object" entry which shows up in the
second pair of brackets, e.g.
[condition][object]Blah=Blah()
What is the purpose? None of the .dsl files in the 5.1 source has it filled in.

Below is the full story of "How I Implemented My First Custom Operator
in Drools". (I gladly admit that I stole much of the code from the
implementations of Drools' own operators, and that I still do not
understand all the subtleties, especially why a negated operator has
to be implemented all over
You can create another event, in parallel to the TestEvent to be monitored, with
a timestamp derived from the external definition. The rule uses the TestEvent
and the sentinel event to check, with "after'" for the TestEvent and "before"
with the sentinel.

Hi,
I want to fomulate in the LHS something like:
after an event happened another event of this kind did not happen for a
specified time (somewhere externally defined).
Unfortunatly, the obvious solution with the temporal operator 'after':
My advice is: Try to avoid the Conditional Element "or". From the
"Expert" manual: "The engine actually has no understanding of the
Conditional Element 'or',..." So, if the engine doesn't "understand"
it, how can we? ;-)
More seriously now, there is general consent that a CE "or" should
