Re: forName() ... ClassNotFoundException

Hi all,
I don't have the stack trace handy, but I've been fretting over an
exception I've been getting and hopefully I can provide enough
information:
There are two classes in the same jar file. One calls the other by
finding its name in a config file and using
java.lang.Class.forName(String) to load it. This works fine when run
in the Eclipse debugger as separate class files, but when run from
within a jar, via a Windows service, the forName call gives a
ClassNotFoundException. We checked the jar, and the target class does
exist, with the correct package name before it and no typos (it did
work in the debugger).
I saw forName is making a call to a method called doPrivileged().. am
I having some sort of permission issue even though it's two classes in
the same jar? What other things might be wrong?
Thanks in advance for your attention and hopefully what help you can
offer :)

What is the class path as defined in the jar file's MANIFEST.MF file? Is
the class that is being loaded within that class path? What is the value
of the String argument to forName()? Is it the fully qualified name of
the class file you want loaded?
