New subject: Calling function in the rule
Is there any way to call java functions in the rule? One option is eval
but eval is quite expensive. Hence trying to see if there is any other
option?
when
Eval($resdirectPhoneNumber.isValidForBrand($croNumberDetailsRequest.getB
rand()))
Then
ResultList.add($resdirectPhoneNumber);
Thanks
Hi,
Yes.
1.
Define a static method in java and import the specific function in rule
file.
DroolsFunction.java
-----------------------------
public static boolean isValidForBrand() {...}
2. import the java function in rule file
invokeRule.drl
import function DroolsFunction.isValidForBrand;
when
exists (
Boolean(booleanValue==true) from
isValidForBrand($croNumberDetailsRequest.getBrand())
)
Then
ResultList.add($resdirectPhoneNumber);
Try this, It should work.
Regards,
Riyaz
