Abstract: Methods are provided for creating a composite program module within a computing ecosystem. The ecosystem comprises physical and/or virtual computing resources of a company, department or other organization. When a user discovers a grouping of modules that is useful to him, the ecosystem or his workspace allows him to create a composite module that comprises the group of modules. He can then access their combined functionality by activating just the composite module, in which case all the modules are automatically opened, without having to activate each one individually. Further, the ecosystem may suggest complementary program modules to a user based on his pattern of activity with one or more other modules. A composite program module may be created to include a suggested complementary module, or just modules discovered independently by the user.

Abstract: A linker or loader, and associated method, is described, whereby the application of security transformations to object-code modules can be deferred until link or load-time, through, for example, memory relocation, selection from diverse instances of a module, and late-binding of constants. This provides several benefits over conventional source-to-source security transformations. These deferred security transformations can be applied in a very light-weight manner and create many opportunities for diversity in the resulting executable program, enhancing security, while at the same time minimizing the impact on execution performance and correctness, and reducing the complexity of debugging.

Abstract: A mechanism is disclosed for enabling a set of code intended to be executed on a first platform (intended platform) to be executed on another platform (target platform). In one implementation, this mechanism takes a significantly different approach than that taken by current techniques. Rather than duplicating, augmenting, or changing a platform to accommodate the set of code, this mechanism alters the set of code to accommodate the platform. By altering the set of code, the mechanism causes the set of code to compensate for the difference(s) between the intended platform and the target platform. By compensating for the difference(s) in the two platforms, the set of code, when executed on the target platform, is able to produce the same result or results as it would have produced had it been executed on the intended platform. Thus, the set of code is able to execute properly on the target platform.

Abstract: A workflow schedule authoring tool enables a user to author a workflow by arranging building blocks in a particular order. Building blocks may correspond to events, conditions or actions. Each building block is associated with source code that defines an action to be taken when the building block is processed. The order of the building blocks determines the workflow schedule process. The building blocks allow a user to establish logic conditions for how the tasks in the workflow schedule are executed. A building block may require a user to input parameters before the building block may be executed. The workflow schedule is associated with an event such that the workflow schedule triggers when the event occurs. The building blocks simplify workflow schedule authoring because the user does not need to write any code.

Abstract: The embodiments described herein generally relate to a method and system of injecting repeatable processes, or workflows, into the processing of data-oriented or procedural requests in an entity management system. A request in such a system is subject to authentication, authorization, and action phases of processing, and workflows may be associated with each phase for automatic processing upon the triggering of a certain request under particular circumstances. A declarative mapping associates workflows with the request type, phase, requester, and target. The mapping may be created at the system administrator level, or by any person with the necessary capabilities, through the application of the processing concept in API or UI and may be consulted and invoked upon receipt of a request matching the mapping's criteria. Mappings may also be created and retrieved to manage state changes resulting from processing in other phases of the request processing model.

Abstract: A system and method for providing a filtering classloader within a Java-based or other application environment. In one embodiment, a filtering classloader is placed between two other classloaders, e.g. between the system classloader and the application classloader. The filtering classloader is provided with a set of patterns which throw a “class not found exception” if an application makes a request for that class or package.

The class may or may not exist in the system classloader; the filtering classloader in essence overrides any retrieval from that classloader in favor of the application classloader, for certain specified patterns of request.
