Infinispan and JGroups discovery on EC2 - spring

Question

I'm trying to use my application on AWS EC2 on some Linux boxes with Tomcat servers. Previously I used my application with Infinispan on LAN and I used UDP multicasting for JGroups member discovery. EC2 does not support UDP multicasting and this is the default node discovery approach used by Infinispan to detect nodes running in a cluster. I looked into using the S3_PING protocol, but I have not figured out why it doesn't work.
Does anyone have any ideas what the problem might be here?
Here is my configuration files:
1. applicationContext-cache.xml
<!-- Infinispan cache -->
<cache:annotation-driven/>
<import resource="classpath:/applicationContext-dao.xml"/>
<bean id="cacheManager" class="org.infinispan.spring.provider.SpringEmbeddedCacheManagerFactoryBean">
<property name="configurationFileLocation" value="classpath:/infinispan-replication.xml"/>
</bean>
<context:component-scan base-package="com.alex.cache"/>
2.infinispan-replication.xml
<infinispan xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</transport>
</global>
<default>
<!-- Configure a synchronous replication cache -->
<clustering mode="replication">

Answer 1

Use this: https://github.com/meltmedia/jgroups-aws
It is an implementation of JGroups discovery protocol for AWS using AWS API (multicast replacement)
