    • Methods and apparatus, including computer program products, implement a hierarchical arrangement of class loaders. Each class loader has a naming token, and each token driven class loader has one or more delegation tokens. A class definition request is received in a first, token driven class loader. If the first class loader has a parent class loader, the class definition is requested from the parent. If the parent is a token driven class loader, delegation tokens are used to delegate the class definition request to the parent. If the class definition is not obtained from a parent class loader, an attempt is made to obtain the class definition from the resources of the first class loader. If that also fails, the delegation tokens of the first class loader are used to find a matching child class loader and the class definition is requested from the matching child class loader.
    • 方法和设备,包括计算机程序产品,实现了类加载器的分层布置。 每个类加载器都有一个命名令牌,每个令牌驱动的类加载器都有一个或多个委托令牌。 在第一个令牌驱动的类加载器中接收到类定义请求。 如果第一类加载器具有父类加载器,则从父请求类定义。 如果父级是令牌驱动的类加载器,则使用委托令来将类定义请求委派给父进程。 如果没有从父类加载器获取类定义,则尝试从第一类加载器的资源中获取类定义。 如果这也失败了,第一类加载器的委托令用于查找匹配的子类加载器,并从匹配的子类加载器请求类定义。
