Is there a ClassNotFoundException anywhere in the complete stack trace?And why are you contacting clients via the Registry? Normally you only put one server in there per server JVM.

No there is no ClassNotFoundException.
Sometimes the client is getting added with the server . in some cases i getting this error message.
And why are you contacting clients via the Registry? Normally you only put one server in there per server JVM.
yes in this case if u r going to add the client to the server the registry count will be increased. here also one server per server JVM....
# 3
Is the client really a server? or is it exporting callbacks? in which case they would normally be registered directly with the server, not bound into a Registry.

Thanks for ur reply...Now i' m getting the access denied problem..

So you have a security manager in the client, so you need to grant it the appropriate SocketPermissions to make that connection.

I am using Eclipse to run the server GUI. and in that how can i use these commands.
# 11
now i am able to get the client into the server when i am running it through the Eclipse 3.2. But i am unable to add the client into the server through the setup which i created. can u help me out......
# 12
As I don' t know anything about 'the setup which [you] created' the answer is obviously 'no', but all you have to do is add that argument to the java command line wherever it is.
