title: Drools drl file and calling from an API call
body: <p>I'm new to Drools and trying to get my head round it all...</p>
  
  <p>I have a rule which I've created in Workbench 6.3.0.Final:</p>
  
  <pre><code>package demo.dummyapp;
  
  import java.lang.Boolean;
  
  rule "RuleThree"
      dialect "mvel"
      when
          SMS(sendMessage == true )
      then
          System.out.println( "This message is being sent" );
  end
  </code></pre>
  
  <p>and from Postman I call using REST API the following:</p>
  
  <pre><code>POST: http://myserver/kie-server-6.3.0.Final-ee7/services/rest/server/containers/instances/dummyapp
  
  {
  "lookup": "ksession1",
  "commands": [{
  "insert": {
  "return-object": true,
  "object": {
  "demo.dummpyapp.SMS": {
  "sendMessage": true
     }
    }
   }
  }, {
  "fire-all-rules": "RuleThree"
  }]
  }
  </code></pre>
  
  <p>The response back from the server is successful:</p>
  
  <pre><code>{
    "type": "SUCCESS",
    "msg": "Container dummyapp successfully called.",
    "result": "{\n  \"results\" : [ {\n    \"key\" : \"RuleThree\",\n    \"value\" : 0\n  } ],\n  \"facts\" : [ ]\n}"
  }
  </code></pre>
  
  <p>however I don't see my println message in the server.log... so I doubt the rule is firing as expected? Any advice I'd be grateful.</p>
