An Internet-based operating system whereby use of data and application software stored on a server may be selectively downloaded to a client device upon request therefrom allowing server-based applications to be accessed and executed on the client device. Because secure communication may readily be established between the server and the client device, many traditional problems of remote data access are overcome. Application software, typically Java code, provides an inherently virus-proof programming language. The end user, operating a client device may access a wide variety of application software with no need to purchase, install, and maintain the software on his machine. Using an easy-to-use GUI, a user selects an application, opens existing or creates new files. The application executable code is identified by a link embedded in a stream of markup language, typically XML. The operating system allows complex applications to be executed on thin clients having limited memory/storage capacity.

There is disclosed a technique for creating a plug and play interface for user actions on a graphical user interface (GUI) on a computer system such as might be used in a client-server network. A text file is prepared in XML language containing all possible user actions. The text file is read by GUI framework application software running on the operating system, and the results are stored in at least one table as Java code. The framework application software calls the Java code in response to user requests. The technique lends itself to modularization and therefore to ease of manufacture of such software plug and play interface. Such software can be easily modified at any time up to runtime.

A computing application for a mobile information device is generated from An extensible markup language, MIDML, in which different types of tags correspond to different application functions. A command line compiler parses the MIDML specification, reading the tags in specialized readers, which are then accessed by generators of specialized objects for an object model using different generators for each type. A predefined set of tags is extendible by the application developer. The generation process results in Java source code, which is then compiled into a MIDlet and packaged into a JAR file and a JAD file.

A method, apparatus, and computer instructions are provided for inlining native functions into compiled Java code. A conversion engine is provided by the present invention for converting the intermediate representation of native functions to the just-in-time (JIT) compiler's intermediate representation. With the converted intermediate representation, an inliner recursively inlines the converted JIT compiler's intermediate representation into the native callsite to remove the need of invoking the native function and subsequent native calls made by the function. The inlining process continues until either a call to an opaque function is encountered or until a JIT compiler intermediate representation growth limits are reached. The inliner also replaces calls to most native functions that are non-inlineable or opaque with calls to synthesized native functions that provide access to native libraries containing implementations of the original non-inlineable calls.

A method for generating localizable message catalogs for Java-based applications is disclosed. Message catalogs that are automatically flagged for what needs to be manually translated are generated from a given Java source code file, which can then be used for translation. ListResourceBundle data structures that are compatible with Java's internationalization model are also generated from the message catalogs that were previously generated and manually translated into desired local language(s). This provides a more efficient means of maintaining a language-specific version of Java software after if has been released.

A monitor analyzes and generates a profile of an Internet website data transmission. The profile indicates the relative load and/or execution times of different components of the data, including text, images, and Java code. The profile is displayed and an end-user deselects one or more of the data components which are of marginal interest but contributing to the webpage load or execution times, whereupon the altered profile is stored. During a next access of the website, the altered profile is retrieved and utilized to selectively control a more limited load and/or execution of subsequently transmitted website data by eliminating the previously de-selected data types. The load or execution times associated with pages of the website are thereby reduced. In one embodiment, the profile is pre-generated and stored with the website data and transmitted in the website data transmission for display and alteration.

A method and system for protecting native libraries for Java and other applications. An application's native library may be embedded in a system of code, such as Java code, so the protections afforded the system of code are provided to the native library. At runtime, the native library may be written to a randomly selected filename in a local file system. The native library is then loaded to support native method implementations. Because the library is written to a different and randomly chosen filename each time, a hacker will not know beforehand what library is going to be used. This invention is generally useful for protecting any native library, regardless of whether it is part of a shared Java library or not. It provides any native library the same level of protection that the symbolic obfuscator, or other method of protecting Java code, gives the Java code.
