Rule flow : Human Task and Tomcat Restart
by KiranP
I have a use case where i have a rule flow which has many HT's
the problem is the web application i m creating is in continual update
process
hence it is required to be restarted again and again ...........
but whenever i restart the server and complete some the human task which
was created before restart would not resume the flow....
I later discovered that it was b'coz of the WSHumanTaskHandler class i used
internally
creates a call back to some other method but when u restart the app-server
the handler
itself is destroyed.........hence the call back is not done...
how i implemented...
i start the task server externally on windows machine......simply >>>>java
StartTaskServer
where in StartTaskServer just start the thread of MinaTaskServer
then i start my app-server(Tomcat in this case) which loads up my
application
then through my application i create a process........
this process contain human Tasks(say A,B,C) and which can be completed at
this time
but now if i would restart the App-server......none of my HT(A,B,C) can be
completed
thanks,

refactoring drools
by Franz Schwab
Hi,
I'm a computer science student and am writing the related-work part for
my diploma thesis and would be interested in (scientific) papers or
information about refactoring or transformation possibilities which can
be done with drools / jboss rules in order to improve design of a
knowledge base or simply to delete bad smells. I have to admit that I
never worked with drools, as I said I just need that for the
related-work part.
Could you please give me some hints?
Thanks,
Franz

Drools + Spring
by Abu Rasheed
Are there any plans to have Spring support in drools-api? The last mail that
I saw in searching the topic is dated last year, and there are no new
postings related to this.
Does anyone have any success in injecting KnowledgeBase into their apps
using Spring? Is there any examples out there that I can refer to?
Thanks

Goodbye Conflict Resolution Strategy, Hello Rule Dependency Meta Rules
by Mark Proctor

------------
Goodbye Conflict Resolution Strategy, Hello Rule Dependency Meta
Rules
<http://blog.athico.com/2010/04/goodbye-conflict-resoltuion-strategy.html>
I've added a new section to the Drools Language Enhancement
<http://community.jboss.org/wiki/DroolsLanguageEnhancements> ideas wiki
page discussing meta-rules to help declaratively control rule ordering.
Here is what I have so far, feedback welcome, you can find the original
content here
<http://community.jboss.org/wiki/DroolsLanguageEnhancements#Field_Versioning>.
Rule Dependency Meta-Rule Language
When a terminal node is matched instead of adding the Activation to the
agenda it inserts it into the WorkingMemory. We have a special builder
that allows easy access to the contents.
All declarations are typed fields for the Activation fact, based on the
"name" field. So the name field is mandatory. All FactHandles are
available via an array accessor, which has type inference for the
element being used. We also all bindings on the Activation fact to work
this way too. Act is used for compactness, we'll allow that to be
optionally user defined:
act1 : Act( someDeclaration == X, fact[0] == Y )
act2 : Act( someDeclaration.value > act1.someDeclaration.value )
Normal facts can also be matched. The RHS of the rule is side effect
free, you cannot modify or insert facts; this allows the RHS to execute
as soon as it's matched. What you can do is setup rule dependencies -
where one rule blocks another:
act1.blockedBy( act2 ).until( Fired )
act1.blockedBy( act2 ).until( IsFalse )
We can even allow facts to block:
act1.blockedBy( someFact )
This means the act1 activation is blocked until a rule executes:
act1.unblockedBy( someFact )
We can probably add an override, something like:
act1.unblockAll()
Only when an Activation is no longer blocked will it be placed on the
Agenda as normal.
If an activation on the agenda has not yet fired and something attempts
to block it, it will be removed from the agenda until it is no longer
blocked.
For this to be effective, especially for large systems, it will need to
be combined with design time authoring help.
This work will be eventually be combined with further enhancements to
help with parallel execution, in resulting conflicts, see the "Parellel
Meta-Rule Language" heading.
