Hi All, I am new to drools and have some how got through my previous issue of updating user defined error object with details. I need help in following items: 1. how to integrate the drools with my Spring application. 2. I have a scenario like i need to write different rules file for different beans ... say i have two beans (Employee, Department) to validate for which i have written two rules file say EmployeeRule.drl and DepartmentRule.drl files. i have a common method where i am passing the object(either employee or Department) that need to be checked. In this case how will i add different drl file in KnowledgeBuilder. Like to validate Employee bean i need to add EmployeeRule.drl file and to validate Department bean i need to add DepartmentRule.drl file. Hope i am making some sense here.. thanks, Ini -- View this message in context: http://drools.46999.n3.nabble.com/Drools-integration-with-Spring-tp397301...
