    Default Sending data from a computer to a server autonomously(spelling?)

    What is the best method to accomplish getting data from my computer to a server so that I can then view it in a applet in a browser?

    I have a sensor attached to my computer, I already have that all done and good and saving the data to a text file( it does close the file stream inbetween writes), I want the data to be updated to a server every 5 minutes or so, I was thinking it might be best to write a little program that just listens for a connection on port #### and if it gets it it takes any incoming data and writes it into a txt file on the server, run that on the server and a write a client that just tries connect and send the txt file every 5 min, is there a better way to do this?

    Would this probably use little enough bandwidth to just keep the connection to the server running all the time and send each data I get(about every 5 seconds) line by line, or lump it into 5 minute updates of 60 lines at once? It is just temperature data, so the time between updates doesn't really matter since it shouldn't change much in 5 min, so really which ever is more reliable is preferred.

    I already have an applet made to display the data also, just need to get that txt file onto the server without me.

    Have you looked at using the Socket and ServerSocket classes?

    Here is a simple tutorial on how to do that.

    A Simple Java TCP Server and TCP Client | systemBash

    And I think that is what you looking for, and one another thing, you must always start server side code because when client requesting from server, if server do not respond it will throw an exception.

    Cool, and I won't ask for C advice here, but there are no problems with writing a server in C and a client in Java are there? As long as the port is the same and all that good shtuff?

    One possible difference could be with int data. The order of the bytes could be different.
