Getting Open MQ and Mule 2.0 work together

Question

Hi!
I would like to ask some help on getting Open MQ work with Mule 2.0. I'm quite new to both technologies, and I can't get them to work together. Here is how I've tried so far:
What I'm trying to achieve first, is that there are 2 queues in my open mq, and if something arrives in one queue, mule should get that from the queue and put it in the other queue.
I've created a configuration file for mule:
(sorry that it looks really crappy, for some reason, couldn't really get it to show nicely on this forum, however I edited it, it always made each line start on the left)
<?xml version="1.0" encoding="UTF-8"?>
<mule xmlns="http://www.mulesource.org/schema/mule/core/2.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jms="http://www.mulesource.org/schema/mule/jms/2.0"
xmlns:spring="http://www.springframework.org/schema/beans">

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
-->
<model name="JMSProba">
<service name="JMS">
<inbound>
<jms:inbound-endpoint queue="MyQueue" synchronous="false"/>
</inbound>
<component class="disp.Dispatcher"/>
<outbound>
<outbound-pass-through-router>
<jms:outbound-endpoint queue="out"/>
</outbound-pass-through-router>
</outbound>
</service>
</model>
</mule>
The service component class pretty much doesn't do anything for now, but is like this:
package disp;
public class Dispatcher {
public Object dispatch(Object o){
return o;
I'm using the Mule IDE, and unfortunately I can't even test if this works or not, because when it starts the mule server, I get an error, which I don't understand why I get:
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'mule'.
I really have no idea why I get this exception. Anyone knows what I did wrong in my configuration file? Also, can anyone tell me, if what I'm trying to do looks something like this, or I'm doing it all wrong? If anyone can help me get this all to work, I'd really appreciate it.
I haven't seen any info on how to configure the Open MQ Connector, so I'm not sure how to do it. I've tried this:
<connector name="jmsConnector" className="org.mule.providers.jms.JmsConnector">
<properties>
<property name="specification" value="1.1"/>
<property name="connectionFactoryJndiName" value="ConnectionFactory"/>
<property name="jndiInitialFactory" value="com.sun.jndi.fscontext.RefFSContextFactory"/>
<property name="jndiProviderUrl" value="file:///C:/Temp"/>
<property name="jndiDestinations" value="true"/>
<property name="forceJndiDestinations" value="true"/>
<map name="connectionFactoryProperties">
<property name="brokerURL" value="vm://localhost:7676"/>
</map>
</properties>
</connector>
but it doesn't work, the error tooltip says "Invalid content was found starting with element 'connector'", and then the next error is at the first 'property' element, saying "Invalid content was found starting with element 'property'. One of '{"http://www.springframework.org/schema/beans":entry}' is expected. "
Can someone please also help me with the connector creation? Since this had errors, I had to cut it out when trying to run my config file, that's why you can't see it in it.
My next step (if this would work) would be to use this on 2 different JMS's - Mule gets the message from a queue from a certain JMS, then sends it to the queue of a different JMS. Of course I can't start working on this until my first task works, but I was wondering, how to create 2 different connectors and then use different connector for each of the endpoints.
Thanks for any help in advance!

Hi Pawan!
Thank you a lot for your help! Unfortunately it's still not working. Here is my current config file:

I have no idea why I get this exception :(
There are a few things I don't understand in your config file though:
-How come we don't have to specify the address where the broker is running? (like localhost:7676)
-In the spring bean called "context", why do you specifiy the Open MQ installation directory? I mean, why do you have to specify it?
-I don't understand everything in the file, so I might say something stupid now... but ... you have a spring bean called "context", and I don't see it used anywhere. Or do you have to have a spring bean called context? Or is this necessary at all?
About the Open MQ admin tool. Am I correct in assuming, that all you have to do, is create a Broker (and add destination to it), and create an Object Store and add connection factory to it (and optionally physical destination too ... although this is not necessary because if you create a destination and you don't make physical destination for it, then by default it will be created for it). This is what I did with Open MQ tool.
I was wondering if you could please give me your email address, would be easier to communicate over that, this forum seems a bit deserted anyway.
Thanks in advance!
