The Virtual Machine is viewed by many as inherently insecure despite all the efforts to improve its security. This invention provides methods, apparatus, and computer products to implement a system that provides operating system style protection for code. Although applicable to many language systems, the invention is described for a system employing the Java language. Hardware protection domains are used to separate Java classes, provide access control on cross domain method invocations, efficient data sharing between protection domains, and memory and CPU resource control. Apart from the performance impact, these security measures are all transparent to the Java programs, even when a subclass is in one domain and its superclass is in another, when they do not violate the policy. To reduce the performance impact, classes are grouped and shared between protection domains and map data lazily as it is being shared. The system has been implemented on top of the Paramecium operating system used as an example of an extensible operating system application.

System and method for enabling dynamic class reloading in an application server environment. A distinction is made between “versionable” and “non-versionable” classes. Versionable classes are classes that should be automatically reloaded when they are modified. The application server(s) may execute a background task that executes periodically to check for modified versionable classes. Users may specify class versionability by specifying a list of explicitly versionable classes, specifying a list of superclasses whose extending classes should be considered to be versionable, and specifying a list of interfaces whose implementing classes should be considered to be versionable. Once the background task discovers a modified versionable class, the background task may cause the class to be reloaded, e.g., by instantiating a new classloader and instructing the new classloader to reload the class. The background task may purge the reloaded class from any caches that the application server maintains.

A method and system for dynamically processing instance data are provided. A namespace manager obtains declarative language instance data including tags, attributes and values for generating user interface objects. The instance data refers to one or more modules registered with a namespace manager in which the modules include meta-data defining one or more class definitions in a class hierarchy. Each class definition defines one or more properties of the class and references to a superclass / subclass(es) for the class. Thereafter, the namespace manager validates the instance data according to the class hierarchy and generates object code for instantiating an object hierarchy having classes, properties and values corresponding to the instance data.

A system and method for automatic invocation of object initializers, or constructors, for superclasses featuring the ability to modify the contents of classes of existing applications at runtime, which includes adding new superclasses to the class inheritance hierarchy of the existing classes. The system redefines the content of classes of the existing classes and the new superclasses during the loading of the classes to additionally include code statements that invoke constructors of the redefined classes and the new superclasses. The invocation of the constructors at runtime performs the initialization of the objects.

One embodiment of the present invention provides a system that facilitates finding terminal classes in a collection of programming language classes, wherein a terminal class is a class that is not extended by any other class. The system operates by receiving a collection of classes. The system then adds the classes to a map of the collection of classes, wherein keys to each class in the map include each class' superclass and the interfaces each class directly implements. Next, the system analyzes a given class in the map of the collection of classes to determine if the given class extends any other class in the collection of classes. If so, the system removes this extended class from the collection of classes. Finally, the system repeats the steps of analyzing classes and removing extended classes until all remaining classes in the collection of classes are terminal classes.

An object-oriented item is used to define the behavior of an item in a dialog box in a windows environment. A class hierarchical library is established with a base class setting up initial definitions of instance variables and methods used to define the behavior of a customized item. An applications developer can create customized items for a dialog box by creating subclasses. The subclasses will inherit portions of the superclasses, and the developer will customize the items by overriding certain methods. The object, an instance of the class, is referenced by a resource associated with an application.

A method and apparatus for type independent permission based access control are provided. The method and apparatus utilize object inheritance to provide a mechanism by which a large group of permissions may be assigned to a codesource without having to explicitly assign each individual permission to the codesource. A base permission, or superclass permission, is defined along with inherited, or subclass, permissions that fall below the base permission in a hierarchy of permissions. Having defined the permissions in such a hierarchy, a developer may assign a base permission to an installed class and thereby assign all of the inherited permissions of the base permission to the installed class. In this way, security providers need not know all the permission types defined in an application. In addition, security providers can seamlessly integrate with many applications without changing their access control and policy store semantics. Moreover, application providers' security enforcement is no dependent on the security provider defined permissions. The method and apparatus do not require any changes to the Java security manager and do not require changes to application code.
