guvnor remote build
by Wesley Akio Imamura
Hi,
I developed a proxy servlet to remotely manage jbrms (drools 4),
adding/removing drl's and building packages acessing the RepositoryService a
year ago. It's very simple, is in production and our integration application
call this servlet extensively to generate the rules and build the packages.
In drools 5 there's a webdav interface in guvnor. I suppose that's only to
manage rules and packages, but not building a package.
So, the questions are:
1) There is any way to remotely to build a package ? (I'm not worried about
selectors at this moment).
2) Can I have an improved solution using webdav ? If I use it, Guvnor
detects changes and automatically build the packages ? (I'm expecting too
much, right ?)
3) I heard about a initial Rest API. Does it have a remote build method ?
Wesley.

How to prevent activation list creation on retracts
by Scott Burrows
I think this question was asked recently but I cant seem to find it.
Using 4.0.7
I have a large number of facts I need to retract from working memory after
all rules have been processed (transaction is completed) so I can insert new
facts for the next transaction. Milliseconds count.
I know that drools recalc's which rules are eligible to be run after each
retraction. Since all facts are being removed its unneeded processing and
time that could be saved.
How can I tell drools that until I tell it otherwise do not re-evaluate the
rules to save time?

detecting when an object has not been inserted
by Chris Richmond
Hello,
The documentation mentions detecting when an object of certain type with
certain values has NOT been inserted within a certain amount of time.for
instance if you have one reading above a threshold and want to see if you've
received an auxillary reading within specs within the last 10 seconds or so,
and if you haven't then take some other action.
Is there a sample of doing this( detecting the absence of a certain object
type with certain values within the last [10 seconds] or so)?
Thanks,
Chris

determining what field changed
by Chris Richmond
Is it possible to determine what fields from an object changed within a
rule.
So I am using this to determine if any DataObject has changed:
//IDENTIFY ANY DATAOBJECT CHANGES
rule "identify any DATAOBJECT"
when
$do : DataObject();
then
System.err.println("ANY DataObject change detected:" + $do);
End
However this also fires when any new DataObject() is injected into the
system and the rules are fired. I would like to be able to only have a rule
fire when an object is first created
Vs. when it is modified and is there a way to detect what values of an
object have changed if I don't explicitly know what fields of DataObject
changed ahead of time?
Thanks,
Chris
