I have done mkdir to create coherent directory with packages example.hello
and put in ~/example/hello the three .java files (Hello.java Server.java
Client.java.
Then i make the class files with a "javac example/hello/*.java"
(I've done things up to here to both the server and the client machines)

Then i start the rmiregistry and launch "java example.hello.Server" on the
first machine.
It says: Server ready

When i start "java example.hello.Client 192.168.10.46" (that is the ip of
the first machine) on the second machine i get these exceptions:

Client exception: java.rmi.ConnectException: Connection refused to host:
127.0.0.1; nested exception is:
java.net.ConnectException: Connection refused

That exceptions seems to say that your client is trying to connect to localhost, not the 192.168.10.46 address you specify. You should take another look at how the command line parameter is supposed to get used in the socket creation code.

Hi William,I think the problem is not there because i was trying to
run a different program without commandline argument.i.e I was hardcoding the value..Do i have to change the java.policy in jre/lib/security....

Look at that exception carefully. Try to imagine what the client trying to do that causes it. Try to figure out why the client is trying to do that.
