Java Security Manager

[Eibhlin Reid]

I am doing a search of the hard drive of a PC through Java and just realised recently that if I don't have admin rights on a PC and I run my program it crashes. Is there some way to get around this using the Security Manager or something else???

Thanks in advance!

how does it crash? do you run into some exception you could catch, for instance?

[Eibhlin Reid]

It gives me NullPointerException, which I have now caught. I just don't really understand why it's giving me this exception and if theres another way around it, other than catching the exception?

[M Beck]

well, it depends on exactly what's giving you this NullPointerException, and on under what circumstances it happens. you'd have to post more details before i could really diagnose the problem.

but as a first rough guess, i suppose that when you're running as non-Administrator you don't have rights to access all the files and directories on the system, and the exception might arise because you're trying to read a file you're not allowed to read. if this is the case, there's nothing you can do except either handle the exception or always run as Administrator; i would then strongly recommend you handle the exception.
