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.

Each component is either an abstract class or an interface, allowing a merchant to vary the implementation of one or more components without affecting the operation of the remaining components of the system in processing transactions. The transactions may be accomplished in a secure environment using a digital container.

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.

A JavaScript program may be represented in an intermediate form to be executed by a JavaScript interpreter. A browser may be configured to intercept JavaScript code and pass execution control to a Java-based interpreter engine. The instructions are converted by a representation generator component of the engine into an intermediate representation equivalent using the Java programming language. The representation scheme may be suitable for execution by a stack-machine implemented interpreter. The representation scheme may use Java classes and objects, and create logical commands representing the JavaScript program. The intermediate representation may be stored as Java objects in a stack data structure. The stack data structure may be constructed from an array of elements, where each element is either an operator or an operand, and where each element derives from an abstract Java class with generic functionality and each element contains data relating to the operator or data type it represents.

The invention provides a method for protecting Java program progress based on an inheritance relationship among the progresses, wherein the method is used for protecting the Java program (the program developed by the Java programming language, hereinafter referred to as Java program) in a windows system (a name of an operating system). The method is mainly used for solving the authentication and determination of the protected Java program progress, monitoring the operating state of the Java program, and preventing the unexpected ending of the operation. The method establishes a father and soninheritance relationship between the protected Java program progress and the protecting program progress, uniquely determines the protected Java program progress by the protecting program progress based on the inheritance relationship and determines the operating state of the protected Java progress based on the inner core object state of the protected Java program progress.

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.

Systems and methods consistent with the invention may analyze a business application's data, operations, and relationships and create a corresponding object oriented programming (OOP) model corresponding to the business application entities. In one embodiment the OOP model may be realized in the Java programming language and may include OOP objects, functions, and operators. Each OOP model accurately represents the data, relationships, and rules associated with the corresponding business entity. Once converted to an OOP model, systems and methods consistent with the invention may use standard OOP tools to understand, manipulate, design, redesign, analyze, and modify the business application. This can be done independently of the native business application system, as the OOP model is separate and independent from the business application entities. Modifications made to the OOP model may then be converted back into business application entities and installed in the native system.
