Abstract: The present technique includes a software framework which makes it possible for providing Business-to-Business (B2B) integration software as a service (SaaS). The framework follows a hub and spoke model wherein the hub and spoke communicate through web services. While the hub and spokes act as integration gateways with the enterprise systems, the hub also acts as a centralized remote command, control and configuration center for the entire setup. The hub software provides the ability to generate and remotely deploy the spoke environments and also manage them remotely. The generated spoke environment can be downloaded, installed and configured to connect to the local systems and act as a mediator for B2B integration between hub and the local systems. Once installed the environments are remotely managed through the management console provided by the hub software.

Abstract: Simulation techniques for measuring the performance of J2EE applications are described. Simulation models for J2EE systems are generated which utilize one or more simulation components comprising queuing centers. The queuing centers employ logic to emulate J2EE thread models by locking on threads when messages are received by simulation components and waiting to unlock until a response is received from every subsequent component in the system. Additionally, simulation components which correspond to J2EE system components running on java virtual machines employ logic which emulates overhead introduced during memory allocation and garbage collection. The simulation models are also utilized during software development in a continuous performance evaluation process which gives feedback at each software development stage based on simulations run using the models described.
