Question on class loading

[abhishek pendkay]

if there are 2 jar files in WEB-INF/lib directory of (a.jar and b.jar), they both have the same class but different implementation, which one gets loaded into JVM/ is it alphabetical? what's the order of precedence?

[Campbell Ritchie]

Don't know. Try it. Remember "name" for a class includes its package.

[Rob Spoor]

I think the official answer is "undefined". But as Campbell said, it only applies if the fully qualified name is exactly the same.
