Abstract: A system performs thread synchronization across layers of code that implement an application, including native code, system code, and code in a virtual machine (“VM”). The system makes a call by the native code to the system code; and sends a message by the system code to the code in the VM. The system then sends a first response by the code in the VM to the system code; and sends a second response by the system code to the native code, where each one of the native code, the system code, and the code in the VM implements wait and notify functionality for communication with other codes that implement the application.

Abstract: Techniques are described for implementing a cloud computer system to provide access to a custom execution environment for execution of custom executable instructions. Users may be able to configure one or more different types of template execution environments, e.g., a virtual machine environment, each of which can be used to establish a type of custom execution environment. Users may configure the template execution environment with regard to settings, states, resources, permissions, or other criterion related to an execution environment. Upon request, a custom execution environment (e.g., a child execution environment) may be established for running one instance of a custom executable instruction. The custom execution environment may be based on the template execution environment. The custom execution environment may provide a secure, isolated environment for execution of a custom executable instruction.

Abstract: A native application built for a mobile device can embed non-native JAVA code that may be executed by a JAVA virtual machine also embedded as a library within the native application. Enterprise applications may be extended for use by mobile devices. Business logic for an application may be constructed just once and then used in both enterprise applications and mobile device applications.

Abstract: A method and code generator system for integrating different enterprise business applications is disclosed. In one embodiment, a method for integrating a local business system with an external business system, comprises using a code generator to generate integration source code, wherein using a code generator comprises; interrogating a repository containing integration data by an introspector; and using the integration data with a code filter, wherein the filter generates the integration source code.
