Added another tweak to this set of functionality. Basically gives the ability
for the client to "stuff" the failover urls in the InitialContext properties
rather than (or in addition to) having them discovered by the server.
So clients can do this:
Properties props = new Properties();
props.put("java.naming.factory.initial",
"org.apache.openejb.client.RemoteInitialContextFactory");
props.put("java.naming.provider.url",
"failover:sticky:ejbd://agwdt:9999,ejbd://127.0.0.1:4201");
Context context = new InitialContext(props);
The "sticky:" part is optional. If specified, it should be any of the
ConnectionStrategy implementations we have installed (sticky, round-robin,
random).
The "ejbd://agwdt:9999,ejbd://127.0.0.1:4201" part is just the critical part
and is just a comma separated list of URIs to try when attempting to connect.
The URIs are the same as you would use normally. Under the covers we just
attempt to find a ConnectionFactory for each URI and ask it for a connection
and keep trying (as per the ConnectionStrategy) till we find one that works.
