Re: [rules-users] Problem calling a function returning String

Remember that inside the eval() block, since you are using java dialect, what you have is java code. So, == is checking for String identity, that is not what you want. You need to call the equals() method: eval( functionThatReturnsString().equals("1234) ) []s Edson 2009/7/7 rainbowflower <al_aysha(a)yahoo.co.in&gt; > > Hi all, > > I am rather new to Drools and I have a problem using functions. > > I have a rule like: > > rule "rule 1" > when > eval(getEVAVersionsNr() == "1234") > then > System.out.println("rule fired"); > end > > The getEVAVersionsNr() method is present in a Java class > "ValidationUtilities.java", which I'm importing in my drl file and it > looks > like this: > > public class ValidationUtilities { > > public static String evaVersionsNr; > > public static String getZEVAVersionsNummer() { > return evaVersionsNr; > } > } > > This static attribute "evaVersionsNr" is set to "1234" from another Java > class before I fire my rules.
