Subject Re: remote ejb scalability issue
Date Wed, 23 Apr 2008 12:04:37 GMT
Hi,
     I finally got a workaround for this issue. If you use
		prop.put(Context.INITIAL_CONTEXT_FACTORY,
				"org.apache.openejb.client.RemoteInitialContextFactory");
		prop.put("java.naming.provider.url", "ejbd://127.0.0.1:4201");

in your remote client then the issue occurs quite frequently. However
if you use 0.0.0.0 as the ip address instead it doesn't. Also due to
the fact that this seems to occur only on windows it may be due to
some issue in the way windows handles loopback addresses.

Regards
Manu
