Hey,
I'm writing a program that has to copy a file from a linux box to a windows server.
The program runs on the linux box.
I have tried to work with java.io.File and java.net.URL.
Booth didn't work on the linux box.
Someone has a working example or can push me in the right direction?
Tx.

Both didnt work on the linux box? How did you use them? And by the way to send a file from one machine to another u need some ftp service, use sun.net.ftp or apache net apis.
The two servers are on the same network.
I developed the program on a windows machine and everything worked fine.
Now the program has to run on a linux box.
Here my two test with file and URL.
String path = \\\\host\\dir;
or
String path = //host/dir;
File file = new File(path);
System.out.println(file.exists());
-
String path = file:////host/dir;
URL url = new URL(path);
URLConnection con = url.openConnection();
InputStream input = con.getInputStream();
input.read();
This code is just an example code.
did u ever try opening the URL from a browser in a different machine - linux or windows?
file://hostname/dir/filename if you are able to open this file from the browser, then your code should work...is there any exceptions? and when you say your code works fine did u try from windows to windows or windows to linux...please be specific with your exceptions...
Code workted find from windows to windows. Now it has to run from Linux to windows.
'file://hostname/dir/' opens up in a browser on a widows machine.
Now we are going to try to solve the problem with samba, so my program writes in locale folder and samba takes care of the rest.
But I was hoping that there was also a java solution.
You have to use telnet or FTP through java;
This code use jscape;
