@ friends,
any solution for my problem ??
org.drools.RuntimeDroolsException: unable to determine ValueType for Class
[class com.fpl.dsm.busrules.parameters.Para_568]

What kind of class is com.fpl.dsm.busrules.parameters.Para_568 when used as
a fact?
What do you mean by saying my getter setter class?
And do show examples (a) where that is used, as a fact in a rule, and (b) as
a field in a pattern constraint.

You've got a problem.
Probably with what your rules are trying to do, possibly with the design of
your fact class.
Use a process of elimination to work out which rule is the problem and
construct the simplest example you can which causes this problem.
Then try working out if there is anything in
Why are you trying to remove a knowledge package while you are in the middle of
running rules? I'm not a drools developer and don't know whether it has been
designed to allow this area of code to be re-entrant but to me it seems like
you are trying to pull the rug (or at least part of it) out
what i've found is that you should always just make things as easy as
possible for the rule engine.
the RETE graph cannot put 'evaluated' conditions into its graph. it can't
make a graph link because the method could evaluate to anything, and
therefore there is no 'cacheing', though i doubt
Hi Drools users,
I've got a situation where I've got a list of Drug codes which can only be
used for certain prescription codes.
The traditional method for implementing this is to simply pre-load the
values in a static Hashmap. Then if get() returns null, it is not a valid
combination. O(1),
Hi!
Anyone with some other thought about this issue?
I'm running out of ideas...

I have tried implemented your idea by creating a method that compiles the

If I understand the chemistry correctly, the relation
mayUse( Drug, Presc ) - Boolena
must be implemented.
Then, the Facts are pairs of MayUseDrug, Presc. To see whether it's valid,
you insert a Fact IsValid containing just the two. If a rule can match
the IsValid to a MayUse, then it's valid
you can create custom audit logs and then query that.. that can be in a
separate database and in a separate machine.
Sorry to not review your problem in depth.

Can I ask what's the goal of finding all the active sub processes of a main
process?
Because for my point of view in most scenarios if you find the active work
items you can create a list of the things that you need to finish. Each
work item can contain a tag (ID, Name) of the process that it
How many match rules do you have? You could always set a single
invalid rule with a low salience (at least lower than your match
rules) that is always true and sets the flag that it is invalid. Then
put all the rules into the same activation-group so that only one can
fire. If the invalid flag
Hi All,
I am evaluating the rule engine of Drools and I have some questions:
1- Is there a way to make the rule dynamic and by that i mean that the
parameter it takes can vary between 1 instance and another?
2- is there a way to set the parameter in java and pass the parameter set
to the

I am observing some strange behavior in drools 5.0.1 which behaved correctly
in 5.1.0-M1.
I have two different ruleflows defined, each with a script task at the
beginning fetching different types of data from DB. It seems that when both
flows are loaded by drools and I choose to execute the

Thanks for the post Thomas. Actually, I wanted to load and unload KBs WHILE I
