When I use the syntax below and write like:

[when]ABC=ObjectA(application==true || banker==true || officer==true)

on drl it gives me the following error:

Multiple markers at this line:

- unknown:116:39 Unexpected token ‘==’

- unknown:116:25 Unexpected token ‘||’

- unknown:116:64 Unexpected token ‘==’

Again, there are NO attributes in ObjectA named application, banker or officer.

Thanks

   Drools respects encapsulation, so it works with javabean method name conventions. If you have a method isApplication() that returns a boolean, does not matter how your class calculates the return value. Same for any other method. In 4.0, you can write:

ObjectA( application == true || banker == true )

   To map that as a DSL, just follow your usual procedure and syntax.

Hi,

If I had a rule written in DSL using Drools 3.0 like;

1. [when] when1=r : ObjectA( )

2. [when] when2=eval(r.isApplication() || r.isBanker())

There are no attributes in class Object with name application and banker but there are methods in ObjectA with names isApplication() & isBanker() which does some work and return Boolean based on some facts.

What is the correct way of writing the same rule using Drools 4.0 ?

Also, if the above attributes were present in ObjectA what would have been the best way to write it in DSL using Drools 4.0

Thanks,
