    Question applets and firewalls

    Dear all,
    I wrote an applet accessing a text file from server for further processing. Right now, its working fine - the applet and the server running on the same PC - "localhost:8080...".

    Is there a possibility that firewalls block my applets when run from Internet,assume trusted applets?
    What might be other risks? I am not using any servlets for handling this bottlenecks.

    Firewall could be a problem with port 8080

    What about using other URLs like www.xxxxx.com?
    May firewalls block the transfer of text files from web server to applets? I am letting them access text files from web servers without serverlets.

    Unsigned applets can ONLY connect to the server they were loaded from.

    if you're a Java applet is, exchange information from the server, it is better that you use either XML or Json, this is more elegant and efficient way of exchanging data between the applet and the server further XML Apis whether Dom or sax are well-defined within the Java runtime.
