Mark,
I am exteremely sorry.
I am new to Drools 3.0 (JbossRules). I had also mailed the same question to
user groups but did not get any response thus far.
I just wanted to know if it is possible to make function calls which do not
have a boolean return type in LHS. If it is not possible in current
implementation will it be addressed in future. I understand that as we are
using AST parser providing this feature should be possible.
Thanks & Regards,
Sriram

I have the following queries regarding implementation using JBoss Rules.
In the LHS part how does one make function calls? I understand that one can
use the eval( function-call ). But this i guess is applicable to only those
functions which have a boolean return type. Say i need to call methods which
need not have a boolean return type in the LHS part, then how do i implement it?
Sample Example
Consider a business/data object "County" with attribute "countryName".
Suppose i need to check if the countryName should match with a predefined name
which will be picked up from the application database :-
rule "DMC validation on chapter value"
when
$country: DataModuleBusinessObject(chapter == Dao.getCountryName());
then
System.out.println("Country does not start with A");
end
Here Dao.getCountryName() is the call to get countryName from database. This
method would return a String value. The above rule does not seem to work.
Please guide me and let me know how to solve this problem and any possible
workarounds. Let me know if the following are possible -
1. To make method calls which do not have a boolean return type.
2. Should all method calls be presented inside eval() ?
Thanks & Regards,
Sriram
