Remote Java Client

[prashb]

Hi,
We have a requirement wherein an IS needs to send requests to a java client running on a remote machine. If the client is down, the IS would know, and it would need to restart this client. Could someone please tell me how to start a java client on a remote machine?
One way I was thinking of involves a java service that would invoke a shell script on a local machine. This shell script would login to the remote machine and invoke a shell script on it which would start the java client on the remote machine.
Is there a cleaner way to achieve this?
Thanks,
Prashanth

Hello,

Is there a reason that you do not want there to be a script on the local computer that manages where it is active? Can you telnet into the remote computer? I think that you can maybe use something like expect.
expect for windows nt

Is this a custom application to run or a cots? That would matter a little for some fancier options. Good day.

Hi,
Thanks a lot for the tips!
The only reason I didn’t want a script on the local computer to manage the client, is because that might require monitoring the script/process too. But otherwise, I agree that would be a simpler process to design.
Expect seems to be an extremely useful tool! I hadn’t thought about that earlier. I will investigate it’s feasibility in the current context.
Thanks again,

Hello,

I would think that would be better. You first wanted to monitor an application is running. So monitoring a process would not seem bad. Now that process could manage the rest of the needed tasks without you. An example would be a multi-threaded java application. You can have one set of threads monitor a port and on receipt of a message of say “alive”, it can send back an “ok”. The thread can check other things are up. Your second thread set can compile a status check on other things running local.

One thing is that this all requires a reliable client computer. No solution will work for your system that keeps crashing or other similar ooh (out of hand) situations. Good day.
