It may not be every day you need to use an object built via a ClassLoader that differs from your current ClassLoader... but when you do... this is the help you need!

Transloader makes two things easy to do:

1. Clone almost any object graph from one ClassLoader to another

2. Take any object from a foreign ClassLoader and invoke any method on it without cloning it

Transloader can deeply clone almost any object (not just Serializables! not just with zero-arg constructors!! even with circular references!!!) from one ClassLoader to another, providing various hooks to adjust how this is done. The cloned object can then be used as any other, as if it had never come from another ClassLoader. The only current restriction is that to be clonable on pre-Java 5 JVMs, any non-Serializable objects in the graph must not have final fields.

If you don't want to clone but just use the object itself, Transloader can also invoke methods on an uncloned, foreign-ClassLoader object. Transloader takes care of: finding the desired Method (as the parameter types can differ between ClassLoaders); cloning the given parameters as necessary; and invoking the method with the potentially cloned parameters.

Originally conceived as a way to use OSGi Services from outside their host Framework, Transloader has been made available without specific ties to OSGi, in case it might be useful elsewhere. It also happens to provide powerful cloning and reflection facilities that are generally useful, not only when crossing ClassLoaders.
