Mule3: RabbitMQ XML schema error?

Question

I try to use mule to receieve message from RabbitMQ, and call remote REST service. My configuration:

<?xml version="1.0" encoding="UTF-8"?>

<mule xmlns:http="http://www.mulesoft.org/schema/mule/http" 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="CE-3.4.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:amqps="http://www.mulesoft.org/schema/mule/amqps"
  xmlns:amqp="http://www.mulesoft.org/schema/mule/amqp"
  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsd
http://www.mulesoft.org/schema/mule/core http://www.mulesoft.org/schema/mule/core/current/mule.xsd
http://www.mulesoft.org/schema/mule/http http://www.mulesoft.org/schema/mule/http/current/mule-http.xsd
http://www.mulesoft.org/schema/mule/amqps http://www.mulesoft.org/schema/mule/amqps/current/mule-amqps.xsd
http://www.mulesoft.org/schema/mule/amqp http://www.mulesoft.org/schema/mule/amqp/current/mule-amqp.xsd.xsd">

  <amqp:connector name="amqpLocalhostConnector" virtualHost="localhost" username="test" password="abc123"
    activeDeclarationsOnly="true" />

  <flow name="amqpChoiceAckNackService" doc:name="amqpChoiceAckNackService">
    <amqp:inbound-endpoint queueName="my-queue" connector-ref="amqpLocalhostConnector" />
    <http:outbound-endpoint exchange-pattern="request-response" host="localhost" port="8081"
      method="POST" path="rmqtest" doc:name="HTTP" />
  </flow>
</mule>

And I added the mule-transport-amqp-3.4.0-SNAPSHOT.jar into the classpath, and I checked the schemas, there is definition of connector, but I still got the following error:

Caused by: org.xml.sax.SAXParseException; lineNumber: 14; columnNumber: 37; cvc-complex-type.2.4.a: Invalid content was found starting with element 'amqp:connector'.

EDIT:

I use mule studio, check the picture below.

classpath

It looks like a problem with your classpath, can you share it with us? — genjosanzo

The AMQP transport is available as a Studio Plugin through the MuleStudio Cloud Connectors Update Site.

By installing it from there you should be able to address the problem. If you need a newer version (i.e. 3.4.0-SNAPSHOT) you can clone the project for its github location and package it with maven.

This way you will generate the update site for the transport yourself
