I don't want to lose the one place where I can confirm that things really can work. Last night I checked it from home, where I have 1.6.0_15-b03 and it did NOT work from my home computer. This verifies that the issue is not some weird security protocol that IT has set up on campus.
I have created a test account in the course. If you want to help me out, login here:
go to Homework09, problem3, and let me know what happens, whether it works or not, and what version of java you have. That way we can know for sure whether it is the java version, or something else.
Thanks so much!
