> Failover Mechanism not working with Remote
> ------------------------------------------
>
> Key: JCS-192
> URL: https://issues.apache.org/jira/browse/JCS-192
> Project: Commons JCS
> Issue Type: Bug
> Components: RMI Remote Cache
> Affects Versions: jcs-2.2
> Reporter: Amol D
> Priority: Critical

> Currently we are using RMI Remote caching and individually i can connect to both the servers indiviadually for example in client if i set
> jcs.auxiliary.RFailover.attributes.FailoverServers=127.0.0.1:5556
> or
> jcs.auxiliary.RFailover.attributes.FailoverServers=127.0.0.1:5555
> then caching works fine
> Further i connect my l client to both the servers as below
> jcs.auxiliary.RFailover.attributes.FailoverServers=127.0.0.1:5556,127.0.0.1:5555
> In this case whenever i cache it always gets added to Primary Server (127.0.0.1:5556) and in case Primary server goes down Caching should be based on Failover server (127.0.0.1:5555) however it is not happening . In case Primary goes down client gets a connection to secondary server (127.0.0.1:5555) is made as per below logs
> 12:42:32.748 [main] INFO org.apache.commons.jcs.auxiliary.remote.RemoteCacheManager - Looking up server [//127.0.0.1:5555/org.apache.commons.jcs.engine.behavior.ICacheServiceNonLocal] 12:42:32.783 [main] INFO org.apache.commons.jcs.auxiliary.remote.RemoteCacheManager - Server found: Proxy[IRemoteCacheServer,RemoteObjectInvocationHandler[UnicastRef [liveRef: [endpoint:[192.168.56.1:5555](remote),objID:[-55e49f52:1641ca4a40a:-7fff, -6827216959955041134]]]]]
> However when i add a new element to JCS Cache in this case it is not reflected so failover seems to be not working please provide a fix for this
