networking - How to set various parameters for Java RMI based communication? -

while performing client-server communication various forums, unable perform remote-object's lookup on client machine.

the errors receive connectioexception(noroutetohostexception), , connectexception , someother.

this not want ask. but, main concern how should setup client platform , server platform --- talking networking details --- doubt interferes connection.

my questions :-

1. how should edit /etc/hosts file on both client-side , server-side? server's ip- 192.168.1.8 & client's ip-192.168.1.100. means, should add system name in both files:

   192.168.1.8    server-1      # on server side 192.168.1.100  client-1      # on client side 

   should edit this? can 1 of possible concerns? want remove doubts left on perform rmi-communication!

2. also, setting server's hostname property using system.setproperty("java.rmi.server.hostname",192.168.1.8); on server side. should same on client-side too?

3. i've read setting classpath while running java program on both server-side client-side. did too,but,again same exceptions. no difference @ all. i've read since java update 6u45, classpaths aren't necessary include! please throw light on too...

4. if missing something, please enlighten same too. brief idea/link resources preferred.

you don't need of unless have problem. usual problem 1 described in rmi faq #a.1, , editing hosts file of server or setting java.rmi.server.hostname in server jvm solution that.

'no route host' network connectivity problem, not rmi problem, , not 1 you'll solve code or system property settings.

setting classpath has nothing network problems.
