[rules-users] Calling function in the rule

[Mohamed Riyaz]

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
