Hi,
we have the following setup. JBoss 3.0.5 and client on the same machine
(Win2000 or WinXP with Java 1.4.1x). The machine is connected to a LAN
(TCP/IP set to automatic, i.e. DHCP).
When we pull the network cord from the network adapter/card and try to
connect to JBoss with our client (look up an EJB via JNDI) we get the
following:
javax.naming.CommunicationException. Root exception is
java.rmi.ConnectIOExcept
ion: Exception creating connection to: 158.234.148.187; nested exception is:
java.net.NoRouteToHostException: No route to host: connect
at sun.rmi.transport.tcp.TCPEndpoint.newSocket(TCPEndpoint.java:580)
at
sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:185
)
at
sun.rmi.transport.tcp.TCPChannel.newConnection(TCPChannel.java:171)
at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:101)
at org.jnp.server.NamingServer_Stub.lookup(Unknown Source)
at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:484)
at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:463)
at javax.naming.InitialContext.lookup(InitialContext.java:347)
The IP address contained in the stacktrace is the one my local machine had
last. When I reconnect the network cord, the lookup works fine again.
Remember, client and JBoss are on my same local machine.
Why does the NoRouteToHostException occur? Is this a special Java problem on
Windows when DHCP ist used? We use jnp://localhost:ourport to connect to the
naming service. Putting in 127.0.0.1 or the "real" IP instead yields the
same results.
Any insight into this would be extremely helpful.
Cheers,
Bernie
