RMI remote Method which returns File object.
Hey
I have a qution using RMI to return files . If I have a a remote method
public File getFile();
method in a Server and I implemented this method to return one file from
my local drive C:\. When the remote Client from different system calls
this method should it return the my File
to that Client or not. i have give allpermission in the policy files.
I have similar example. When I run the Client from a different system I
don't get the File
object instead when I run the Client from myy system in another window
without the required classes in the classpath I get the File.
Can Any one let me know what could be the problem? I am attaching the
Server, ServerImpl, Client and policy files for review if required.

Re: RMI remote Method which returns File object.
Posted by Tom Drake <rt...@pobox.com>.
Sucharitha:
A File object represents a files name (and location).
It does not represent or store the contents of a file.
Therefore, using RMI to pass a File object around doesn't
make much sense. It is likely that a File object
that points to a valid file on the client is completely
invalid on the server. Worse yet, it is valid, but points
to a different copy of the file.
If you need to transfer a file from one side of an RMI
connection to another, you'll need to read the file into
a buffer of some sort and pass that across your RMI
interface.
This explains why your client program only works when
you run it on the same computer as your server.
