Examples of VFSClassLoader

org.apache.commons.vfs.impl.VFSClassLoader
A class loader that can load classes and resources from a search path VFS FileObjects refering both to folders and JAR files. Any FileObject of type {@link FileType#FILE} is asumed to be a JAR and is openedby creating a layered file system with the "jar" scheme.
