Sample drools project to test out agenda-flow, salience and using Generics and Complex Events Processing

mvn clean package exec:java -Dmaven.test.skip=true -Dexec.mainClass="com.redhat.app.App"

or for CEP

	mvn clean package exec:java -Dmaven.test.skip=true -Dexec.mainClass="com.redhat.app.CEPApp"

Complex Event Processing Test case:

Client (CEPApp.java) is setup to run rules in AccountRulesCEP.drl

Generates 50 ATM activity events, 5 fraudent ATM activity events (same accound Id, different ATM locations)

Number of activities are adjustable.

    private static int NUM_OF_RECORDS=50;
    private static int[] fraudlist = {4,5,9,12,34};

drl will detect 2 activities across different locations within a 10m windows and raise an alert

inserting event id: tx_45 location: NORTH customer:acct_45 amount:80
audit rule 1 acct_45
inserting event id: tx_46 location: WEST customer:acct_46 amount:378
audit rule 1 acct_46
inserting event id: tx_47 location: NORTH customer:acct_47 amount:45
audit rule 1 acct_47
inserting event id: ftx_34 location: NORTH customer:acct_34 amount:1000

Detected potential fraud for the following activities: 
ATM tx1 : id: tx_34 location: WEST customer:acct_34 amount:602
ATM tx2 : id: ftx_34 location: NORTH customer:acct_34 amount:1000
!!!! Registered fraud event!!!!

ATM activity at 2 locations detected for account:  acct_34

inserting event id: tx_48 location: WEST customer:acct_48 amount:460
audit rule 1 acct_48
inserting event id: ftx_12 location: WEST customer:acct_12 amount:1000

Salience, agenda flow test cases:

Client (App.java) is setup to run rules in AccountRules1.drl followed by AccountRules2.drl using agenda-group

Order within drl file is managed via saliance value

Data Object:

Customer.java has a Generic attribute of Account type (with subclasses OrdinaryAccount & SpecialAccount). Use instanceof keyword to match the correct class type and attribute in the drl file.

Output :

***Test with Ordinary account, accountrules2 should be invoked first, followed by salience****
Agenda-group accountrules2 invoked, saliance 100
Account status: ordinary-3
Agenda-group accountrules1 invoked, saliance 50
Account status: ordinary-2
Agenda-group accountrules1 invoked, saliance 45 
Account status: specialordinary-1
Agenda-group accountrules1 invoked, saliance 20
Account status: ordinary-1
****Test with special account, accountrules1 should be invoked first, followed by salience****
Agenda-group accountrules1 invoked, saliance 45 
Account status: specialordinary-1
Agenda-group accountrules1 invoked, saliance 30
Account status: special-3
Agenda-group accountrules2 invoked, saliance 10
Account status: special-1
Agenda-group accountrules2 invoked, saliance -5
Account status: special-2
