[jboss-user] [JNDI/Naming/Network] - UnknownHostException when doing a lookup in JNDI

Wed Oct 3 06:15:59 EDT 2007

I have JBoss installed on my server (OpenSuSE linux 10.2). When I trying to lookup a bean in JNDI I get the following exception:
javax.naming.CommunicationException [Root exception is java.rmi.UnknownHostException: Unknown host: aloe; nested exception is: 
	java.net.UnknownHostException: aloe]

Actually, the server's domain network name is aloe (LAN) but it is visible to external clients (via Internet) as myserver.domain.com.
My jndi.properties file has jnp://myserver.domain.com:1099/ url.

Server is launched with -b 0.0.0.0 key to enable access from the network.

How to tell the server that he should not use aloe hostname for clients outside the local network?
