Thanks for the reply Greg. I am looking at the documentation. http://ehcache.sourceforge.net/documentation/distributed_caching.html

I am a novice here; so please bear with me.

For automatic peer discovery setup; do I set the following values for multicastparameters ?

 multicastGroupAddress=230.0.0.1, multicastGroupPort=4446

 

Also, can I enable/disable distributed cache just by the use of a parameter ? As I want to use the same ehcache.xml for different environments but on some machines I want distributed cache; on others not; so I would like it to be enabled/disabled just by using some parameter/variable.

 

    System property tokens can be specified in this file which are replaced when the configuration is loaded.
    For example multicastGroupPort=${multicastGroupPort} can be replaced with the System property either
    from an environment variable or a system property specified with a command line switch such as
     -DmulticastGroupPort=4446.

I have the Distributed cache set up for ehcache.

I have 2 servers on the network; apollo and logos .

 

On Apollo ehcache settings are :

<cacheManagerPeerProviderFactory

 class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"

 properties="peerDiscovery=automatic, multicastGroupAddress=230.0.0.1,

 multicastGroupPort=4446, timeToLive=32"/>

 

<cacheManagerPeerListenerFactory

  class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"

   properties="hostName=apollo, port=40001,

 socketTimeoutMillis=2000"/>

 

<cache name="<theClass>"

        maxElementsInMemory="10000"

        eternal="false"

        timeToIdleSeconds="300"

        timeToLiveSeconds="600"

        overflowToDisk="true">

 

        <cacheEventListenerFactory

            class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"/>

     </cache>

 

On logos settings are :

 

<cacheManagerPeerProviderFactory

 class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"

 properties="peerDiscovery=automatic, multicastGroupAddress=230.0.0.1,

 multicastGroupPort=4446, timeToLive=32"/>

 

 <cacheManagerPeerListenerFactory

 class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"

  properties="hostName=logos, port=40001,

socketTimeoutMillis=2000"/>

 

<cache name="<theClass>"

        maxElementsInMemory="10000"

        eternal="false"

        timeToIdleSeconds="300"

        timeToLiveSeconds="600"

        overflowToDisk="true">

 

        <cacheEventListenerFactory

            class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"/>

     </cache>

 

I get the following exception a few min. after the servers start up
