Re: [rules-users] DROOLS Negate Question

Thanks Michael for the immediate response.
Yes.The rule has been defined in guided web editor.
I had taken sample respoitory ( Pricing Loan guided web editor rules) and added the negate option in the row-1 of the rules and Validating the rules throws the error posted earlier.
Here is the source of the rule-1 ,
1. | #from row number: 1
2. | rule "Row 1 Pricing loans"
3. | dialect "mvel"
4. | when
5. | not (
6. | application : LoanApplication( amount > "131000" , amount <= "200000" , lengthYears == "30" , deposit < "20000" )
7. | income : IncomeSource( type == "Asset" )
8. | )
9. | then
10. | application.setApproved( true );
11. | application.setInsuranceCost( 0 );
12. | application.setApprovedRate( 2 );
13. | end

I need help to clarify the following
I had taken latest Guvnour 5.2.0 M2 version and use the sample pricing loan rules.
When i tried to use the "Negate" Meta data option and set it to true on first rule , i had got the following error.
Pricing loans] [ERR 102] Line 7:3 mismatched input 'income' in rule "Row 1 Pricing loans"
[Pricing loans] Line 16:0 unexpected exception at input 'rule'. Exception: java.util.EmptyStackException.

I have a similar requirement where in I need to write both negate with true and false within the same ruleset in guvnour. Please help me out how to achieve this.

5.2CR1
by jkrupka
Any idea when 5.2CR1 will be out? I started testing our app against 5.2M2
today.. no problems so far other than the performance test I did took about
2x as long using 5.2M2 as it did using 5.1. I know there are some
performance regressions in 5.2M2 that were fixed in CR1 so I don't want to
try troubleshooting something that have already been fixed.

Guvnor test scenarios public no-arg constructor
by Lisa Horton
It appears that in order to be used in a Guvnor test scenario, an class must have a public no-argument constructor. Is this true? And if so, is there a workaround for classes that have a private constructor (other than changing the object model)?

Re: [rules-users] drools-server
by Abhay B. Chaware
I tried the latest one on tomcat.. drools-camel-server-5.2.0M2.war
To get things to work to some extent, I had to do this -
1. change the rsServer address from "/rest" to "/kservice/rest" in camel-server.xml
2. change the route from "direct://kservice" to "direct://kservice/rest" camel-client.xml
Then test.jsp gave me this reponse.

Hi, I was refactoring and fixing some issues with Drools Server. The 5.2 version can be deployed out of the box into jboss/tomcat/jetty without any modification as far as I know. Can you try this new version?
Greetings.

Hi
I am trying to get the default drools-server.war (drools-5.1.1-server.war to be specific ) to work on tomcat.
When I access http://localhost:8090/drools-5.1.1-server/kservice/rest , I am getting “No service found” in the browser and in the console,

Need help setting up Drools Server using Maven
by kkelleyjr
If it is not completely apparent by the subject line I am a complete noob to
Drools and Maven...
I have done a lot of reading and I think the Drools Server exposed through
soap will work for my design...
I have found some material to get me started, but I am perplexed by a very
simple issue...
Using Maven what archetype do I use to set-up the project... Using that
archetype how to set-up the packages under the archetype... And where do I
get the dependences for the drools server to set-up the server with spring
configuration... (Yes I am a noob to spring also)
I could hack at it and surely get some format to work... But I do not want
to find out later that the set-up does not grow with the project... So what
are some best practices... I have looked and can not find them or if I did
find them I am to much of a noob to understand them...
The project will have clients of the Drools Server service.
The project will have Java classes fired by the rules. These classes may
have to become exposed web services later, I just don't know yet...
Thanks for any advice, sorry for the noob post... I have just run out of
ideas to get this off the ground...

DSL Enumeration / Decision Table ?
by matiasklein
Hi,
I have a DSLR that reads:
There is an event with a code of "93000"
This translates via DSL to:
[when]There is an event with a code {Code}=$event : Event(Code == {Code})
Unfortunately, I have to build many rules that are exactly the same as this,
but with different qualifying codes (i.e. rule #1 qualifies with code 9300,
93001, 93002, etc., but rule #2 qualifies with 5001, 5002, 5003, etc.).
I would like users of the system to be able to maintain the list of
qualifying codes in a spreadsheet. However, I'm not sure how to use an
enumeration loaded via a spreadsheet.
Does anyone have a recommendation on how to achieve this?
Thanks so much!
Cheers,
Matias
