Running Linux batch file from windows in java (!)

[AlistairMonkeyFinger]

Hi,

Maybe not strictly a java question but... i have a Java program i am working on, it runs on a Windows PC and needs to do the following:

1.) Copy a file from windows to a Linux server

Easy enough, set up samba on linux and use java.io classes.

2.) Execute a batch file (.sh) on the Linux server which runs a program which does stuff on the server to the previously copied file

3.) Read data froma new file which has been created from step 2.)


Steps 1 and 3 are not a problem, however, i am stuck on 2. Any ideas ? I can't just run the batch file from windows as i want it to run on the server (not the machine that is calling the script). I didn't want to go down the route of having a java "server" sitting on the Linux machine which i could contact and tell it to run the batch, what other options do i have ?

Thanks for any ideas

None (that I can think of) !

Basically you are asking how to start other processes (ie a shell script on linux) from a remote computer - ie you are attemping distributed computing.

For this, I would look into RMI - see the tutorials at

Thanks Sedj, i guessed i would have to use RMI maybe. One other option maybe to set up a Java daemon on the server polling for a file to be created, once it appears then i could get it to fire the script off using Runtime.exec()

Is there a good way to listen for a file being created in java (i.e. some kind of event listener) or do i need to poll on a timer (which is a bit nasty) ?

Thanks
