Bela Ban commented on JGRP-1543:
--------------------------------
RELAY2 on the *original sender* of a message to an unreachable site X gets an event
SITE_UNREACHABLE sent up the stack. This can be caught in a JChannel setting an UpHandler,
or using an RpcDispatcher by creating a subclass and overriding handleUpEvent().
The latter case is relevant for Infinispan: CommandAwareRpcDispatcher extends
RpcDispatcher and it should now override handleUpEvent():
{code}
protected Object handleUpEvent(Event evt) {
switch(evt.getType) {
case Event.SITE_UNREACHABLE:
SiteMaster unreachable_sm=(SiteMaster)evt.getArg();
short site=unreachable_sm.getSite();
String site_name=SiteUUID.getSiteName(site); // "SFO"
// do something with the site
break;
}
return super.handleUpEvent();
}
{code}
