To test Drools, send some message to session1. As a result, session3 will receive this message.

4.2 This example describes mixed DSL/Drools calls.

Add the following business rules configuration:

  1. Routing- Other blocks besides messageRules can be called

  2. Rule1- General Routing based on message type

  3. Rule2- Custom Drools call

    Code Block
    import com.epam.fej.routing.RoutingContext
import com.epam.fej.routing.drools.DroolsEngine

import static dsl.CommonRulesDsl.rulesDSL

DroolsEngine dre = drools as DroolsEngine
rulesDSL(routingContext as RoutingContext) {
    routing {
        from "session1" to "session2"
        from "JMSProducer" to "JMSConsumer"
    }
    messageRules {
        messageRule("Rule 1: Route FIX messages only through DSL instructions.") {
            condition { msgType "AE" }
            action {
                sendTo "sessionAE"
                context exit
  }
        }
        messageRule("Rule 2: Route FIX messages only through Drools rules.") {
            source { id "ksession1" }
            condition { msgType "B" }
            action {
                custom { ctx ->
                    dre.runStatefulAndClean("ksession1", ctx)
                    routingContext.getDestinationById(ctx.messageEvent.getHeader 
                    ("destination")).send(ctx.messageEvent)
                }
