cdrom access though java

[Adam Gordon]

Hello,

I'm trying to write a java program that will access a cd-rom drive. I just
want to treat the drive as one big file where I can grab bytes off of.
Right now I can use java.io.RandomAccessFile to do that.

One that that I can't figure out is how to have my program detect if there
is actaully a cd in the drive instead of just throwing an I/O exception. My
reason for wanting to make this distinction is that if the CD is scratched
there will also be an I/O Exeption, and I want to handle those dirrerently.

Thanks,

You have no such interface in Java. Unfortunately the interfaces to the
file system in Java leave some things to be desired.

Consider using JNI.
