[jboss-user] [Beginners Corner] - remote access to ejb :java.rmi.UnknownHostException
I'm using JBoss 4.2.2
I have a server where an ejb project is deployed and a client in which there is the
following code:
anonymous wrote :
| Properties p = new Properties( );
|
p.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
|
p.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
| p.put(Context.PROVIDER_URL,"jnp://172.19.1.194:1099");
|
| Context context;
| try{
| context = new InitialContext(p);
| NavSenderRemote beanRemote = (NavSenderRemote)
context.lookup("WSNavEAR/NavSenderBean/remote");
|
| Random r = new Random();
| int lat=r.nextInt(100);
| int lon= r.nextInt(100);
|
| beanRemote.setPosition(idUtente, lat, lon);
|
| }catch (NamingException e){
| e.printStackTrace();
| }
Both client and server have the -b 0.0.0.0 option so they can have remote access.
If I run this code on the server itself it works, instead if I run it on the client
machine it gives the following error

I'm starting to suspect my code works only on the same JVM. If this is the case then
what kind of code should I use to work with another machine?
Thanks in advance for your help
