Re: In Classpath

This depends a bit on the way the classloader is implemented. If you've
got the same class in different jar files, the classloader normally
will load the first class with the exact fully qualified name it finds.
The standard classloader will normally go through the classpath in
order it is defined. So the first jar containing the class in the
classpath will provide the class. The other jars will simply be
ignored.
Again, this depends on the implementation of the classloader. Remember
that classloaders are not required to take the classpath into account
when loading classes.
