Abstract: A system and method for usage-based application licensing in a hypervisor virtual execution environment. In accordance with an embodiment, the system comprises one or more computers, each with a hypervisor operating thereon and forming a hypervisor environment, together with one or more virtual machine images executing within that hypervisor environment. Each hypervisor aggregates usage statistics by each image instance for physical resources, and reports the statistics to a management framework. The management framework uses the statistics to ensure the system is adequately licensed with usage units. An initial allocation of usage units is recorded in the image and accessed during execution by the hypervisor. As the usage units near expiration, the hypervisor can signal that a particular image is about to become unlicensed. The management framework can then either allocate more usage units, shut down the image, or audit the unlicensed usage for later compensation.

Abstract: The present invention defines a mechanism for automatic synchronization of scripting variables in an action tag extension facility. Attached to each action, there is a TagExtraInfo class that describes the action. The TagExtraInfo class knows the attributes of the class, including the names of the scripting variables introduced or modified by the action. At translation time, a tag handler accesses the information from the TagExtraInfo class for each tag in a page. At run time, a pageContext object is created containing a mapping of scripting variables to values. The values are visible to the scripting code, and the scripting code can modify the values. Also, the values are accessible by the action code. The action code can modify the values or create new values and assign the values to scripting variables so that the scripting code can modify them later. Thus, the present invention allows action tags to be created without explicit knowledge of the scripting language used to create a page.

Abstract: A multi-lingual tag extension mechanism suitable for use with the JAVASERVER computer software Pages platform. Rather than creating a closure abstraction, the present invention “in-lines” a body evaluation for the tags. A doStart ( ) method processes a start tag and determines if a body needs to be evaluated. If so, a body evaluation buffer is passed to a doBody ( ) method for body evaluation. Once the body evaluation is complete, a doEnd ( ) method completes the processing by synchronizing the variables. The scripting details of the present invention match any nesting of the tag, so the at the structure corresponding to the original scripting is preserved. Furthermore, the present invention is not dependent on the specifics of the scripting language used to form the Web page.

Abstract: Methods, software, and apparatus for analyzing a software component within an application builder tool are disclosed. The present invention relates, in one aspect, to a method for analyzing a software component that can be visually moved within an application builder tool running on a computer. The method involves obtaining the software component to be analyzed and determining if the software component has an associated information class. When it is determined that the software component has an associated information class, the information class is queried about information stored within the information class, otherwise automatic analysis using design patterns is applied to analyze the class. In one embodiment, the information stored within the information class relates to methods, properties, and/or events.

Abstract: The present invention is directed to providing an ability to re-host, or port, an object oriented graphical user interface implementation from a native window-based platform, or environment, to another window-based platform, or environment. Exemplary embodiments abstract any notifications (e.g., events, state changes or "interests") which occur in the native environment as behavioral specifications. These behavioral specifications, (i.e., traits or protocols) can be used as part of a conformance negotiation to determine, during the execution lifetime of the graphical user interface, whether a particular client side object will conform with the behavioral specifications which have been abstracted from server side events associated with a different object. Where the conformance negotiation proves successful, abstract notifications can flow between particular instances of objects to model the state of the system, rather than using native implementations of events.

Abstract: Methods, software, and apparatus for customizing a component for use with an application builder tool are disclosed. A method for customizing a component which has at least one associated property with an associated data type involves obtaining the component, obtaining an editor that is arranged to modify the property, and adding the editor to a customizer that is associated with said component. Then, the property is modified using the editor. In one embodiment, the method further includes configuring the component by implementing the modified property. In another embodiment, the component is an instance of an associated component class, and obtaining the component involves obtaining the component class and creating the instance of the component class. In such an embodiment, each property associated with the component is identified.

Abstract: A method and apparatus for mixing Objective-C and C++ objects includes the step of defining a common object as an Objective-C object class data structure. In addition, the common object is specified as a C++ object class data structure. Thus, the C++ object class data structure is equivalent in memory layout to the Objective-C object class data structure. A set of behavioral operations to be performed in relation to the common object are then established in either Objective-C or C++ source code. A selected behavioral operation is subsequently performed in relation to the common object in response to mixed Objective-C and C++ source code instructions.

Abstract: The present invention provides efficient methods, apparatuses, and products for customizing software components intended for use in application builder tools. In accordance with one aspect of the present invention, a method of customizing a component which has at least one associated property involves obtaining the component and then identifying a customizer that is arranged to be associated with the component. Such a customizer is further arranged to guide a user through the configuration of the component.
