[rules-users] PackageBuilderConfiguration

[Saleem Lakhani]

I am switching from Drools 2 to 5.

Do we still do the following in Drools 5:

 

Properties properties = new Properties();

properties.setProperty( "drools.dialect.java.compiler", RULE_COMPILER);

PackageBuilderConfiguration conf = new
PackageBuilderConfiguration(properties);

How do we do that?  Since we are using the rules server, all we are
doing is calling with an HTTP call with the object and the rules flow we
want to call. We then receive back the results as the HTTP response.

Did you notify the engine that your data has been updated?

Hi, I have a very simple rules flow that I am getting odd results from.
For now, our project is planning on using spreadsheets  and a drools
server.

 

The test project we are working on accepts a movie name from an external
source and creates a Movie object that is passed to the rules.   The
first rule looks at the movieName attribute and assigns it a movieStar
using the Movie objects setMovieStar call.  We have printLn statements
before and after this action to confirm that it does in fact work.  

 

The second rule, where things go wrong, checks the MovieStar attribute,
but no matter what we've just set it to, it always uses the value
("NoStarYet") that was originally created when we create the Movie
object in our Java code in the condition of our second rule.  We've
tried using the getMovieStar call in the condition, but it has been
throwing errors when we startup the Drools Server.

 

When we retreive the Movie object from the resultSet, the movieStar
attribute is set correclty, but we can't get our flow to go as expected.


 

This really seems like a simple issue, but we've had no luck with it.
Any thoughts?  Does the rules engine use the getter methods for
conditions or does it use the values from the entityXML we pass in?  Is
there a way to make the engine update the object between running each
rule?  

 

Any help is appreciated greatly.
