I am trying to integrate mule with drools, I have mainly followed the tutorial here but I am getting this error :

"The prefix "vm" for element "vm:endpoint" is not bound."

can anyone help me solve this problem?

following is my .drl file and mule flow files.

    </flow>
</mule>

and the drl file :

global org.mule.module.bpm.MessageService mule;    
import com.me.mit.esb.*;
 
rule "La Vita Ebela"    
dialect "mvel"

when
    $x:XMLDTO( inputXML == "inputXML" )
then
    mule.generateMessage("emc",  "KeyValueMatched", null, MessageExchangePattern.ONE_WAY);
end

You have to add XML namespache and scema reference to your xml file:

XML namespace:
   xmlns:vm="http://www.mulesoft.org/schema/mule/vm" 

XML Schema Location:
http://www.mulesoft.org/schema/mule/vm http://www.mulesoft.org/schema/mule/vm/3.6/mule-vm.xsd

So it looks like so:

<mule 
    xmlns:bpm="http://www.mulesoft.org/schema/mule/bpm"
    xmlns:vm="http://www.mulesoft.org/schema/mule/vm" 

    xmlns:http="http://www.mulesoft.org/schema/mule/http"
    xmlns:tracking="http://www.mulesoft.org/schema/mule/ee/tracking" xmlns="http://www.mulesoft.org/schema/mule/core"
    xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"
    xmlns:spring="http://www.springframework.org/schema/beans" version="EE-3.6.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation=

  • thanks for pointing that out. i did what you told and now i am facing : org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'vm:endpoint'. – MoienGK Jan 28 '15 at 12:34
  • @dave do you have added `mule-module-objectstore` to jor classpath? – Jens Jan 29 '15 at 06:12
  • I am using anypoint studio so the required libs are included. – MoienGK Jan 30 '15 at 07:01

Replase vm:endpoint by vm:inbound-endpoint. As Jens said, add vm schema to your mule-config. And don't forget to include mule-transports-vm-3.6.0.jar to your test classpath.

  • thanks for reply. i am using Anypoint studio, so i guess the mentioned jar file is included. (i checked under mule server 3.6.0 and the dependecy is there) – MoienGK Jan 28 '15 at 14:17
  • I see your problem now, you should use vm:inbound-endpoint instead of vm:endpoint. I'm Updating my answer. – Ale Sequeira Jan 28 '15 at 14:22
