Java APIs

Hi,

I am running my server on a remote machine. The client tried to access the remote machine and I get the following error:

Receiver exception: access denied (java.net.SocketPermission hostname resolve)

the policy that I am using is

grant {
permission java.security.AllPermission;
};

the server is bound fine but still when I run the client I get the above error

another question is, my stub is located in server, connection is not HTTP connection, so how can I make sure the stub is accessible by the client for download?

Thanks,
S.
