Drools multiple params in action sout

I have the following code (Here is the decision table) and I need to put multiple params to console output. How can I do it?

Solution

  • If both components change from row to row, it may be useful to have two action entries. If a constant should be appended, add it in the code snippet in line 3:

    ACTION             ACTION
System.out         System.out
print($param)      println($param + "!")
part 1             part 2
"The city is: "    $city.getName()
"No such city"     ""

    As an alternative, use

    ACTION
System.out
println( $1 + ", " + $2 )
both names
$country.getName(),$city.getName()
