How to create a complex Rule in Oracle Business Rules?

Question

Hi, I have this classes:
public class User{
private List<Country> countries;
public List<Country> getCountries(){
return countries;
public class Country{
private String name;
public String getName(){
return name;
Is it posible to create a rule to evaluate if one of the countries of a User has its name equals to "USA" ? How can I do that?
I 'm evaluating this product but find that I only can create rules with very simple conditions.
Thanks in advance for your help.

Answer 1

1) Write a function that takes a List and a String and return true if the list is in the String.
2) Assert a fact
class UserCountry {
User u;
Country c;
to link the Country facts to the User facts.
3) Use an Advanced form pattern (in RuleAuthor) to do
fact User u &&
u.getCountries().contains("USA")
