Hi All, Is there a way to retrieve an object array from a Class getter in the when clause of a rule in a drl file ? I have tried a lot of things but they did not work out. The Problem is detailed below :- The following class has a private parameter Column1 which is an Object type array. public class EightColumnGenericClass { private Object[] Column1; /** Getters and Setters */ public Object[] getColumn1() { return Column1; } public void setColumn1(Object[] column1) { Column1 = column1; } } Following is the method where I am creating the knowledgebase and utilizing it. I am reading a file record and splitting the columns. The columns[] array gets saved into the attribute of the class defined above. public static void fnReadFromFile(String FilePath, String FileName){ /* Declarations and other code */ while ((str = brReadFromFile.readLine())!=null){ Columns = str.split(","); ecgcPLC = new EightColumnGenericClass(); ecgcPLC.setColumn1(Columns); ksession.insert(ecgcPLC); } ksession.fireAllRules(); } I have to try and retrieve each cell of the Columns[] array in the entire collection and apply rules on individual cell. My drl file is given below. rule "SourceSystemId = value" when c: EightColumnGenericClass() Object[] columns: c.getColumn1(); for (Object o : columns) { System.out.println(o.toString()); # The condition I want here is - if (o.toString()=="1794") } then #RHS Code end Is there a way to achieve this? Or is there something missing with my DRL file? Please assist.
