I'm trying to create a pop-menu to communicate via network
I'm trying to implement javascript within a text file. My goal is to create a a command that sends a pop-up message to another computer's desktop via LAN when a text file is modified from the networked computer that stores the text file.
Is this even possible with java alone? Does it depend on my network ?
Is normal file sharing capabilities adequate for this type of communication or do I need another application in between.
I would really appreciate the right advise to this issue!
