Ehcache jms replication websphereMQ

I'm trying to setup the Ehcache replication using JMS WebsphereMQ v7 as a provider. I did this replication using ActiveMQ and everthing is ok, but I'm trying to figure out which class I need to use to create a initialContext.

This is the current code using ActiveMQ and working good, I good it from this post.

ehcache.xml

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="ehcache.xsd" 
updateCheck="true"
monitoring="autodetect" 
dynamicConfig="true">
<diskStore path="java.io.tmpdir" />
<cacheManagerPeerProviderFactory

properties="initialContextFactoryName=ca.toyota.testcache.cache.ActiveMQContextFactory,
    providerURL=tcp://127.0.0.1:61616,
    replicationTopicConnectionFactoryBindingName=topicConnectionFactory,
    getQueueConnectionFactoryBindingName=queueConnectionFactory,
    getQueueBindingName=ehcacheGetQueue,
    listenToTopic=true,
    replicationTopicBindingName=ehcache"
propertySeparator="," />


<cache name="cacheTest1" 
    maxEntriesLocalHeap="10000"

    timeToIdleSeconds="300" timeToLiveSeconds="600"
    memoryStoreEvictionPolicy="LFU" 
    transactionalMode="off">
    <persistence strategy="localTempSwap" />

    <cacheEventListenerFactory

                 replicateUpdatesViaCopy=true,
              replicateRemovals=true,                                                
              asynchronousReplicationIntervalMillis=500"
    propertySeparator="," />
</cache>

ActiveMQContextFactory.java:

    package ca.toyota.testcache.cache;

import java.net.URISyntaxException;
import java.util.Hashtable;
import java.util.Map;

import javax.naming.Context;
import javax.naming.NamingException;

public class ActiveMQContextFactory extends ActiveMQInitialContextFactory {
    @Override
    public Context getInitialContext(Hashtable environment)
            throws NamingException {

        Map<String, Object> data = new ConcurrentHashMap<String, Object>();

        // Configure the Topic connection factory binding name
        String factoryBindingName = (String) environment
                .get(JMSUtil.TOPIC_CONNECTION_FACTORY_BINDING_NAME);
        try {
            data.put(factoryBindingName, createConnectionFactory(environment));
        } catch (URISyntaxException e) {
            throw new NamingException("Error initialisating ConnectionFactory"
                    + " with message " + e.getMessage());
        }

        String topicBindingName = (String) environment
                .get(JMSUtil.REPLICATION_TOPIC_BINDING_NAME);
        data.put(topicBindingName, createTopic(topicBindingName));

        // Configure queue connection factory binding name
        String getQueueConnectionfactoryBindingName = (String) environment
                .get(JMSUtil.GET_QUEUE_CONNECTION_FACTORY_BINDING_NAME);

        if (getQueueConnectionfactoryBindingName != null) {
            try {
                data.put(getQueueConnectionfactoryBindingName,
                        createConnectionFactory(environment));
            } catch (URISyntaxException e) {
                throw new NamingException(
                        "Error initialisating TopicConnectionFactory with message "
                                + e.getMessage());
            }
        }

        String getQueueBindingName = (String) environment
                .get(JMSUtil.GET_QUEUE_BINDING_NAME);
        if (getQueueBindingName != null) {
            data.put(getQueueBindingName, createQueue(getQueueBindingName));
        }

        return createContext(environment, data);
    }

}

Finally my question is: Which InitialContextFactory I should use to work with WebpshereMQ.

Thanks
