示例1: getURL

/**
* Gets URL with nbfs protocol for passes fo
* @param fo
* @return url with nbfs protocol
*/

// operation. Sometimes a user class loaded internally (customized bean...),
// which has no privileges, needs to make and use an nbfs: URL, since this
// may be the URL used by e.g. ClassLoader.getResource for resources.
