The present invention provides a method, apparatus, and computer instructions for mapping and labeling XML schema elements and types. In an exemplary embodiment, each XML schema element and type is uniquely labeled, using distinguishing parameters such as namespace to create name parts like a Hashing code and suffixes in order to achieve unique mapping. The parameters selected are predetermined in order to achieve naming that remains distinct across successive consumptions of a schema. The selection disclosed accomplishes unique labeling, while also permitting one to still adhere to the strict naming standards of the target language (e.g., Java). As a result, schema components belonging to multiple namespaces can be mapped to Java components belonging to a single package.

The mechanism includes three data structures: object data associated with each object O1, O2, O3 ... of a program, a class descriptor associated with the classes to which the objects O1, O2, O3 ... belong, and interface references. For each class Ci, the class descriptor corresponding to the class Ci includes: i) a class method table comprising one or more entries, wherein each entry identifies an implementation of a method inherited or defined by the class Ci; and ii) for each interface implemented by the class Ci, an interface method table comprising one or more entries, wherein each entry identifies an implementation of a method declared by the particular interface or an implementation of a method declared by an interface extended by the particular interface. An interface reference for an interface declaration ID associated with a given object OI, wherein the object OI implements methods that are declared by an interface declaration ID includes a pointer to the interface method table corresponding to the interface declaration ID within the class descriptor corresponding to the object OI. An efficient mechanism for method invocations is provided by generating an index that identifies the entry corresponding to the appropriate method in the interface method table pointed to by the pointer of the interface reference, reading the data stored by the entry identified by the index, and controlling the computer processing apparatus to jump to the address identified by the data.

A method, system, and program storage device for establishing security and authorization policies for users accessing a software application, wherein the method comprises generating at least one application object group from an application object description document comprising an XML format run on a data processor; creating an authorization policy for each application object; sending a selected application object group to an access controller; and establishing access control parameters at a time of deployment of the software application for users attempting to access the selected application object group based on the authorization policy. The method further comprises specifying environmental variables for the authorization policy; changing the authorization policy by modifying a declarative specification of the environmental variables and modifying constraints defined on attributes of an application object; implementing varied classes of authorization policies using a same authorization policy classifier; and specifying the application object group using grouping parameters.

A method and system for tracing profiling information using per thread metric variables with reused kernel threads is disclosed. In one embodiment kernel thread level metrics are stored by the operating system kernel. A profiler request metric information for the operating system kernel in response to an event. After the kernel thread level metrics are read by the operating system for a profiler, their values are reset to zero by the operating system kernel. The profiler then applies the metric values to base metric values to appropriate Java threads that are stored in nodes in a tree structure base on the type of event and whether or not the kernel thread has been reused. In another embodiment non-zero values of thread level metrics are entered on a liked list. In response to a request from a profiler, the operating system kernel reads each kernel thread's entry in the linked list and zeros each entry. The profiler can then update the intermediate full tree snapshots of profiling information with the collection of non-zero metric variables.

The invention provides a program monitoring method and device. The program monitoring method comprises the following steps: writing in a skip instruction for positioned objective functions so as to perform a hook operation; distributing hook functions to registered Java callback functions, and preventing created temporary variables from being collected by a garbage collection mechanism of a system; enabling the objective functions which are not processed to skip back to hook positions, or else, continuing to process the objective functions. Through the adoption of the program monitoring method disclosed by the invention, any Java function of an Android system under an ART mode can be monitored without destroying the stack of the objective functions, so that the garbage collection mechanism of the ART can perform normal memory collection. The invention further provides a program defending method and device, which realize a defending mechanism of the Android system under the ART mode by adopting the program monitoring method disclosed by the invention.

A method and system of generating target applications from Java reference applications for a particular combination of mobile devices is provided. The method includes the steps of: a) unpacking the reference application into a number of class files; and b) transforming the reference application into the target application by a device plug-in. The device plug-in is capable of transforming different reference applications into corresponding target applications for a particular combination of the reference mobile device and the target mobile device. The system includes a transformation engine and a device plug-in corresponding to the reference / target mobile device combination. The device plug-in includes an XML file and pieces of software code to modify corresponding portions of the reference application not supported by the target mobile device. The XML file directs the transformation engine to identify the unsupported portion of the reference application and to modify the portion with the selected software code.

In an information network, an interactive display allows a user to choose products or elements on one screen axis (Y) and compare their characteristics or attributes on a second screen axis (X), thereby aiding a user to select a product from all available information according to the user's individual requirements. The information network includes at least one knowledge site containing product information for access by a user through a terminal. The terminal includes a processor coupled to an interactive display and a storage disk. The processor includes a Java operating system; an application program for processing product information by categories in terms of elements and attributes, and a browser enabling a user to access and interact with the knowledge site through Java applets. The disk contains product information by category received from the knowledge site and transformed into the form of HTML parameters within HTML files.

A method for enterprise application integration that uses “connectors” that can be instantiated via downloading (e.g., using Java® or other such technologies) to provide interfaces to respective disparate database systems. The databases systems may comprise any variety of now or heretofore known systems, e.g. SAP, Oracle, and so forth. The connectors can, for example, translate between a native language (or API) of the respective database systems and an internal language / protocol of the enterprise application integration system. To this end, the connectors can utilize a scripting language to access the respective database systems. Data retrieved from the database systems can be stored in a central data store in the form of RDF triplets, from which directed graphs can be generated for to generate presentations consolidated from the multiple database systems.

A method includes receiving a portion of JAVA™ language software having a declaration of an instance of a generic class, parsing the declaration into a token corresponding to the generic class, and generating an intermediate language code block corresponding to the parsed declaration. The intermediate language code block is executable by a runtime engine. A system for compiling includes a parser receiving JAVA™ language source code having an instruction referencing a generic class and specifying a type of the generic class, and a code generator generating intermediate language code representing the source code.
