[jboss-user] jndi service take too much time to response

Hi, I have built the sample stateless application Calculator in JBOSS EJB3 tutorial. The Calculator and JBOSS is installed in another machine 192.168.1.242; whereby I execute "ant run" in another machine 192.168.1.235. But it takes about more 1 minute to show up the result from the command "ant run". The property of the jndi.properties file is shown below: java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces java.naming.provider.url=192.168.1.242 The 192.168.1.242 and 192.168.1.235 systems has no internet access. I don't know whether I need a DNS server setup for that? Thanks
