[ajug-members] multiple jar versionsfor one application

[Eugene Thompson]

Chris,

I'm sure I'm missing something, but there seems to be some practical
issues with what you are trying to do. First, how would the compiler
or jvm know which version of the class you wish to instantiate each
time? Second, you would need to have multiple locations where the jar
file was stored so you didn't overwrite one with another.

Why would you not just use inheritance to solve this issue? Then you
could just place the sub-version of the WorkerBee class
(WackyWorkerBee.class) in the same jar. Do you not have access to
these jars? 3rd party? And you want to use both implementations? There
might be a way to solve this problem in a more traditional manner. Can
you give more context for the issue?
