I just picked up a book on Java and built a short program. I can read from a file and there are write functions(classes) available. I put my program on the web to see it run. I doesn't. I get security protection errors attempting to read from a file. Why? What good is Java if I can't read from or write to a file when using the web? Is there something I don't understand about I/O functions in Java on the web? Any program of value has to have these abilities.
Thanks for any suggestions you may have.
Whoever responds to this question, please give detailed information. Thanks again.
