Subject: I hate java.lang.NoClassDefFoundError


It's amazingly frustrating when you run the beanbox and get the
message:

	java.lang.NoClassDefFoundError

And it just hangs.

Can't you make it at least give the name of the class that it can't
find?

EVALUATION If Beans.instantiate catches any kind of error while instantiating the class it throws a ClassNotFoundException with no detail message. It was probably a mistake to use ClassNotFoundException for a range of errors, but we're definitely stuck with the existing set of exceptions thrown by Beans.instantiate. The right anser may be to add a more helpful detail message to the ClassNotFoundException. KGH 7/28/97 We now supply more information on the exact problem as part of the detail mesaage in the ClassNotFoundException. At the same time, I've also made sure that if we get an exception while deserialing an object we remember that exception and thow it if we can't find the class later. KGH 7/29/97
