Method facilitating data stream parsing for use with electronic commerce

A parsing technique suitable for use in electronic commerce that avoids the disadvantages of known monolithic parsers. The parsing system generates code specific to each input document and data stream type, which may then be updated as needed to handle document-specific idiosyncrasies without requiring modifications to the core parser code. As a user (10) defines parsing rules for extracting data from a representative sample document (15), a visual trainer (16) automatically generates code in the background, referred to as a filer (17), that is specific to that document and that embodies the rules for extracting data from that particular document. The generated code may be modified manually (18) as needed to account for any idiosyncratic conditions associated with the document. Each representative document has associated with it its own filer. A parsing engine (20, 21) comprises a collection of such individual filers appropriate for the types of documents that arise in any given organization. A mapping or other association is maintained between representative document types and their filers. In regular operation, a user selects a data set to be extracted from certain documents. When the parsing engine receives a document in an input data stream, the associated filer is loaded and parses that document for the selected data set. Then another filer is loaded in response to another input document, and so on. The filers may be especially efficiently generated using an object-oriented approach and then dynamically instantiated at run time as may be conveniently achieved, for example, in the Java programming language.

Java and native application window integration

A system for adding functionality to a graphical user interface of a non-Java based, or native, application, using the Java programming language is provided. A Java window, or dialog, is configured to be accessible by a native application. While the native application is executed in a first thread, a Java dialog is launched in a second thread. Execution of the native application in the first thread is then continued. The Java dialog next calls the native application and registers itself with the native application. Also, the native code can control the Java dialog like other dialogs supported by the native code. A command for a Java dialog from a native application is routed to an invisible dialog. The invisible dialog passes that command to the Java dialog through a native interface connection. A very seamless integration between the Java and native code thus occurs. The graphical user interface operates and visually appears as if controlled from a single source of code.

Optimizing symbol table lookups in platform-independent virtual machines

One embodiment of the present invention provides a method for increasing performance of code executing on a platform-independent virtual machine. The method operates by receiving a request to resolve an entry in a symbol table at run-time, wherein resolving the entry requires multiple lookups into the symbol table. It next determines if the entry has previously been resolved. If so, the system returns a direct pointer to a runtime structure associated with the entry, which was returned during a previous resolution of the entry. If not, the system resolves the entry through multiple lookups into the symbol table to produce a direct pointer to the runtime structure, and replaces the entry with the direct pointer. In a variation on the above embodiment, the symbol table assumes the form of a constant pool within an object-oriented class file defined within the JAVA programming language. The present invention speeds up constant pool resolution substantially without requiring a significant amount of additional space. Therefore, the present invention is especially valuable for embedded JAVA systems or other applications that have strict size limitations.

Method and apparatus for activating/deactivating run-time determined software routines in Java compiled bytecode applications

ActiveUS20050097534A1Mitigate and obviate known disadvantageNot prevent Java JIT optimisationSoftware engineeringProgram controlSun MicrosystemsJava Programming Language
The invention concerns the use of a Java JIT compiler to change the status of run-time determined software routines between being activated and deactivated in an application program. Conditional statements which are used at run-time to determine whether such a routine has been activated or deactivated are presented as discrete conditions that always evaluate to a known result by using an invariant flag in the compiled bytecode. The JIT compiler optimises an application program by excluding discrete condition checks. Consequently, if the branch of the discrete condition that will never execute includes a run-time determined software routine, then the routine will be excluded from the JIT compilation and will not form part of the JIT compiled native machine code. A run-time class or code replacement facility is used as a means of activating or deactivating a run-time determined software routine at run-time by changing the value of the invariant flag of said routine. Such a facility is provided by Sun Microsystems' Java programming language HotSwap class file replacement feature of its Java Platform Debugger Architecture (JPDA). International Business Machines (IBM) also provides a similar functionality called “Hot Code Replace” (HCR) for its “J9” JVM platform.
