I am thinking about learning java for a program I am going to write. Actually it is going to be an applet. I need to know if I write an applet that remains on teh server can it write to a file and then read from it. Like if I wanted to make an applet that creates a database. Everytime a user signs up it adds them to the file and saves the file. Next time the user runs the applet they will already be in the file. This is simple to do in C++, but I don't know anything about Java security. Can this be done? How would you permantly save something in a java applet. In C++ I could just write it to a file and next time read from that file. Is this possible in a java applet?
