Re: [rules-dev] Fwd: I need help, guided editor rules in the drools-examples-brms dont work

Yes, I did it, in the package configuration. I use the drools-4.0.0-brms  
version. The problem is at the moment to evaluate the next generate code  
of the rule:

then
		Rejection fact0 = new Rejection();
		fact0.setReason( "Driver too old" );
		insert( fact0 );

If I use the Technical rule text editor, i dont have any problem.

Greetings from Chile :)

[rules-dev] Rule's duration attribute will change rule fire sequence?

When I running TroubleTicketExample in Drools4.0. I make follow change:

1)       comment  “t3.setStatus( "Done" );” and “session.update( ft3, t3 );” in TroubleTicketExample.java file.

2)       Comment rule "Escalate" and "Done" in TroubleTicket.drl

3)       Change three “… Priority” rule’s duration to 1000 , for the "Platinum Priority" rule need add duration attribute

 

We know the sequence which Ticket object insert is ABCD, so if no duration the “… Priority” rule fire and print sequence should be DCBA. But when I used the duration I found actual sequence change to ADCB. The last A be changed the first order. Even I use salience specify the sequence to DCBA, it still run in ADCB sequence. It seems the duration canceled salience affect, and change the last rule to first fire.

 

I think it is a bug , is it ?

Re: [rules-dev] Fwd: I need help, guided editor rules in the drools-examples-brms dont work

please continue this conversation in the user mailing list, as this list 
is for the drools developers, not users.

[rules-dev] Featured Drools Job - Tier One Investment Bank

http://blog.athico.com/2007/08/featured-drools-job-tier-one-investment.html <original blog link>

Caspian One is the first company to place a job advert on the Drools Job Board, as such I thought I'd give it wider promotion :)

Intro: Caspian One is working with a tier one investment bank who is looking to recruit a Java Developer to work within the Credit Derivatives Front Office. Project description the successful candidate will be given the opportunity to develop MiFID integration feeds in the Drools framework. The team is responsible for hands on development of implementation, feeds, integration and database infrastructure for an in-house MiFID solution. This is all using SOA strategies, JBoss Drools framework, JDBC, relational database design and SQL coding with either MS SQL or Sybase. Also an essential is good knowledge of modern Java development; Spring /Hibernate. The candidate must have a proven track record of being able to work in a highly dynamic environment with some experience in investment banking. As such we are looking for candidates with good Java skills, who can design database using either MS SQL coding or Sybase and the must is good experience using Drools.

Sales bit: The successful candidate will gain excellent exposure to investment banking business areas, as well as the opportunity to work in a technically challenging, delivery focused environment, within a fast moving business areas.

You can view and apply for this this role at the Drools Job Board here.
