SQLException accessing CD-ROM in Win 98

Question

I've created a Java application that connects to a PointBase database stored on a CD-ROM. On Windows NT, 2000, XP, I have no problem running my application. However, on Windows 9x, I get the following error message, and my application exits:
java.sql.SQLException: Cache manager I/O error. Access is denied.
Can anyone think of a reason why I'm getting this error? I beleive it has something to do with the way Windows 9x machines access CD-ROM drives.

Something like [url http://search.java.sun.com/search/java/index.jsp?qp=&nh=10&qt=jad+jode%2C+%2Btitle%3Adecompile&col=javaforums]this. Just so you can find out where to download it, instructions,...
Here's the steps
1. Get the stacktrace
2. Find a likely class where the problem might be
....lets say the class is com.pointbase.OpenDB (initialize() method)
3. Extract the classfile from the jar
....jar -xf pb.jar com/pointbase/OpenDB.class
4. Decompile the class
....jad OpenDB.class
5. Look at the file
....notepad OpenDb.jad
6. Find the method (initialize())
7. Rinse, repeat until you find the problem
It's probably calling some system function in a DLL somewhere, but you need to get some clue what that is.
