Dependency with JBoss
by Joj
Hi,
In the Drools documentation, it's written that :
"The rule workbench (for Eclipse) requires that you have eclipse 3.2 or
greater, as well as Eclipse GEF 3.2 or greater. "
My application contains a GUI for building rules which 'll be converted into
some format - .drl or xml - which is understandable to Drools, and saved in
database. My Qn is : Is there any dependency for Drools with JBoss server?
Plz reply A.F.A.P.
Thanks in advance,
Jojan

objects
by Chris Mathrusse
I'm new to the rules syntax and a bit frustrated with trying to learn it. I've
reviewed the docs but keep running into the same issue. I have a parent object,
Message, that contains an Order. An Order has a status that I want to test. So
looking at the documentation and taking my best guess I've created a rule as
follows:
rule "Order not Accepted"
when
$m : Message( state == MessageState.RELEASING, order.requestStatus ==
RequestStatus.ACCEPT )
then
...
end
The problem is that when I start my application I get a compilation error.
Caused by:
org.drools.rule.InvalidRulePackage: [54,54]: unknown:54:54 mismatched token:
[@423,1899:1899='.',<69>,54:54]; expecting type RIGHT_PAREN[54,94]:
unknown:54:94 mismatched token: [@433,1939:1939=')',<37>,54:94]; expecting type
LEFT_PAREN
at org.drools.rule.Package.checkValidity(Package.java:368)
So what am I missing? I know it has to be something simple with my understanding
of the syntax.
Thanks for the help...

RE: rules-users Digest, Vol 7, Issue 15
by Wagner Rick - rwagne
Hi all,
I'd like to make a comparison of two attributes on the same object, but
would like to do it in one line to facilitate easy DSL.
Example:
Class Tree{
int oldNumberLeaves;
int newNumberLeaves;
}
What I'd like to say is "when the oldNumberLeaves > newNumberLeaves
then...."
Can anyone give me a tip on this one?
Thanks much,
Rick

DSL editor
by Chris Mathrusse
I'm using JBoss Rules 4.0MR2. I've installed the Eclipse IDE as well and
begining to work with the DSL editor. It seems to be rather easy and intuitive
except for one thing. The editor provides edit fields for Expression, Mapping,
Object and scope. All of which make sense except for Object. What is this used
for? There doesn't seem to be any reference to this field in the documentation.
Can someone please privde me with an explanation and perhaps an example?
Thanks very much....

DRL to Decision Tables
by suma
Hi,
Is there anyway to convert a DRL file into a Decision table.
This means that what ever changes are made to the DRL file should be
reflected to the decision table.
Or is there any other way in which the customer should be able to make
changes to decision tables through DRL file.
Please help me as early as possible
I have posted the same message two days back,but not received any
replies....
Please do the needful
