exposing drools as a webservice
by Prem Kumar L
Hi,
I am trying to setup a basic webservice that exposes a rule running on
drools. In this regard I came across this blogpost by Mark Proctor a
while ago.
http://blog.athico.com/2007/05/working-with-jboss-rules-and-web.html
Incase someone has a working sample of such an example, it would be
great if you could share it with me. IF this is not possible, can you
point me to a resource where I could access such a sample. I am new to
the SOA world, so kindly bare with my if this seems to be a
straightforward question. Any pointers would be much appreciated.
Thanks

rule execution problem - internationalization
by Dejia Wang
hi all,
we tried to write rules in chinese like follows
rule "Reorder alert when item expires"
salience 10
when
$item : ImsItemRecords ()
then
if ( ! (new Date()).before ($item.getExpireDate()))
{
SysAlert alert = new SysAlert("过期 - " + $item.getItemName(), "补充库存",
"很高", "新到", new Date(), null);
SysRecommendation recommendation1 = new SysRecommendation (alert,
"补充库存", "购买" + $item.getAmount() + $item.getUnit() + $item.getItemName(),
"仓库管理人员", "立即");
...
HashSet recommendations = new HashSet();
recommendations.add(recommendation1);
...
alert.setSysRecommendations(recommendations);
insert (alert);
}
end
The rule was executed, but the result is unexpected. some of above chinese
characters (for example, "新到") are good; some of above chinese characters
become ??? after rule evaluation.
any tips how to fix this.
thanks- dejia

Question about insertLogical
by Gras, Patrick
Hello,
I have a question because insertLogical does not behave as I expected.
Here is the example I use; I have a class 'cat' that is dynamic (JavaBean with PropertyChangeSupport ) with only a 'name' attribute.
Then I have following rule:
rule "test"
when
$cat:Cat( name == "tom" )
then
$cat.setName("cat");
insertLogical(new String("test"));
end
When I test the rule against a cat named tom, the logical inserted fact is not retracted. (So the fact is inserted because the rule matches, but is not retracted even if the rule is no more matching at the end.)
If I change the order of the RHS, it works fine. The fact is inserted and then retracted.
rule "test"
when
$cat:Cat( name == "tom" )
then
insertLogical(new String("test"));
$cat.setName("cat");
end
Is that the normal behavior ?

Nullpointer inserting fact.
by psyduck
Hey,
I ve got a class
WebService{
getter/setter for invoke property
}
then i got the following rules
rule "..."
salience 10
when
$web : WebService ( )
then
Invoke inv = new invoke();
$web.setInvoke(inv);
insert(inv);
end
this succeeds,but then the following rule :
rule "..."
salience 9
when
$inv : Invoke( )
$web : WebService ( invoke == $inv);
then
...
end
never gets executed,because he doesnt find a webservice with same invoke,
(according to debug information,they are the same invoke object)
Is it possible that this happens because when i inserted the webservice in
the workingmemory, the invoke
property was not yet defined(=null)?
Does anyone know a solution for this?
Thx in advance

RE: [rules-users] Help in using drools
by Hehl, Thomas
That would be one way to accomplish this. For your situation, though, I
would use a stateless session since your servlets are stateless.
One of the things I'd like to see changed in drools is that, while it does
complicated processing and returns complex answers very well, it's difficult
to return simple answers. I would like to see methods like
fireRulesReturningBoolean kind of thing, but it would require a paradigm
shift in the rules themselves. Alas!
Anyway, I think that's how I'd handle it. I also construct wrappers around
the basic data types to receive these answers. I wish Sun would implement
the bean interface for Integer, Long, Character, String, etc. It would
certainly be simple enough for them to do, and then we could just use those
to hold the values coming back from our rules.

Subject: [rules-users] Help in using drools
Hi,
I would like to use drools in my application. However, there are a few
things that I do not quite understand and whether it can fit my
requirements. I have tried to search through the documentation and mailing
list, but to no avail.
Here is my situation. I am creating a web-based application which requires
me to run certain rules for certain page. What I need is to pass all the
information accumulated from the pages and pass it through a rule engine.
Each rule will check the information and return string message(s) to the
caller. Does drools fit in this requirements?
>From what I understand, I can create a stateful session, passing the
information to the rule engine. But when I need to return the result, how
do I do that? Do I pass an empty String List into the rule engine, and each
rule will add the message to the List if there is an error?
Thank you.
Regards,
Leonard Soetedjo

Re: Drools 4.0.7 released
by Edson Tirelli
Vijay,
Please send the e-mails to the list, not directly to other people's
e-mail.
Your error looks to me like you are using a wrong version of some
dependency, but since I don't know much about the BRMS code, maybe someone
else can help you.

Are there plans to integrate fuzzy logic into Drools?

Problems with drools update site?
by Bagwell, Allen F
I'm wondering if anyone else has had problems updating Drools within Eclipse? I have no problems with other plugins, but with Drools I've never been able to use the update site. After making sure that Drools is uninstalled from Eclipse and attempting to add it via the remote site, I always get an Eclipse message stating:
"No features found on the selected site(s). Choose a different site or site category."
In addition, several of the developers on my team who did manage to get the update site to work cannot get it to recognize that 4.0.7 is now available. The "search for updates of the currently installed features" doesn't return 4.0.7 as ready to upload when they have 4.0.4 installed. If they try to detect 4.0.7 as a new feature, they get the same message above that I've been getting about no features found.
I've re-checked the URL and re-copied-n-pasted it several times from the web site. We are all using Europa and trying to use the "Drools 4.0.7 Eclipse Workbench for Europa 3.3" URL.
Any suggestions?
