Applets are severly restricted in what they can do.
Here is a list to give you a general idea as to what an applet loaded from a network is prohibited from doing.
[list=1][*]Access to the local file system is not permitted. Applets cannot read from or write to the local file system. Applets cannot find out any information about the file so this means finding whether the file actualy exists or the modification date is out of the question.
[*]Applets cannot launch other programs on the client.
[*]Applets cannot load native libraries or define native method calls.
[*]The use of System.getProperty() is not permitted where information about the users machine like username is returned.
[*]An applet can only open a network connections to the host from which it was downloaded from.
[*]Applets cannot listen on ports below 1024 with IE not even allowing this.
[*]If listening is allowed the applet can only accept incomming connections from the host which the applet was downloaded from. [/list=1]
