Hi Joe,

You should be able to override the default configuration by apply a new configuration like this.
{code}
    CacheComponent cache = context.getComponent("cache", CacheComponent.class);
    cache.setConfigurationFile("classpath:test-ehcache.xml");
{code}

If you want to do the configuration per endpoint you can let cache endpoint lookup the cache manager factory like this 
{code}
       String CACHE_ENDPOINT_URI =
            "cache://myname1?cacheManagerFactory=#testCacheManagerFactory";
       CacheManagerFactory testingCacheManagerFactory = new FileCacheManagerFactory("src/test/resources/test-ehcache.xml");
       jndi.bind("testCacheManagerFactory", testingCacheManagerFactory);
{code}

You can find more examples of those configuration from the unit tests of camel-cache.

> Camel-cache component has a default ehcache.xml file embedded and it is used for configuring ehcache. It configures a cacheManagerPeerProviderFactory to use a built-in RMI-based distribution system by default which unfortunately relies on multicast:
> {code}
> <cacheManagerPeerProviderFactory         class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
>             properties="peerDiscovery=automatic,
>                         multicastGroupAddress=230.0.0.1,
>                         multicastGroupPort=4446, timeToLive=1"
>             propertySeparator=","
>             />
> {code}
> It sometimes causes a problem when deploying a camel cache route due to multicast/network configuration on it's host. 
> We should not rely on multicast in default ehcache configuration that is enforced by ehcache.xml from camel-cache component jar. We should either remove it from the jar to allow fallback to ehcache-failsafe.xml file from ehcache library or modify the embedded ehcache.xml to avoid relying on multicast.
