I am new to drools, and have a scenario, where I need to invoke a mule flow from drools. I have defined mule flows as below and want to invoke one of the flow based on some condition. 

<flow name="Flow1">
    <http:listener config-ref="flw1" path="/check1" doc:name="Evaluation Srv" />

    <http:request config-ref="Proxy" path="/check1" method="GET" doc:name="basic validation" />
</flow>

<flow name="Flow2">
    <http:listener config-ref="flw1" path="/check2" doc:name="Notification" />

    <http:request config-ref="Proxy" path="/check2" method="GET" doc:name="Personal validation">
    </http:request>
</flow>

I have a sample drools file, as below

#default dialect for the semantic code will be MVEL
global org.mule.module.bpm.MessageService mule;

import com.mule.sbus.drools.RequestUrl

dialect "mvel"

declare RequestUrl
    @role(event)
end

rule "/check1"
    lock-on-active
when
    $url:RequestUrl(url=="check1")
then
    #invoke flow1
end

rule "/check2"
    lock-on-active
when
    $url:RequestUrl(url=="check2")
then
    #invoke flow 2
end

Please let me know how to invoke the flow from drools

If you know how to invoke it from Java, then you know how to invoke it from Drools. The Right Hand Side (then part) of a rule is basically Java code. One thing to have in mind though, is that the execution of the rules in Drools is single-threaded. No other rules will be executed/evaluated while you are invoking mule inside a rule.

An option would be to use an asynchronous executor.

Hope it helps,
