“…The dynamic nature of the OSGi means that the bundles can be installed, started, stopped, and uninstalled without the necessity to restart the OSGi framework [4]. For this purpose, the OSGi framework runtime provides standard methods [2] for the exploration of the bundle's context (i.e., environment) and the control of its life cycle.…”

Abstract-The component-based software development enables to construct applications from reusable components providing particular functionalities and simplifies application evolution. To ensure the correct functioning of a given component-based application and its preservation across evolution steps, it is necessary to test not only the functional properties of the individual components but also the correctness of their mutual interactions and cooperation. This is complicated by the fact that third-party components often come without source code and/or documentation of functional and interaction properties. In this paper, we describe an approach for performing rigorous semi-automated testing of software components with unavailable source code. Utilizing an automated analysis of the component interfaces, scenarios invoking methods with generated parameter values are created. When they are performed on a stable application version and their runtime effects (component interactions) are recorded, the resulting scenarios with recorded effects can be used for accurate regression testing of newly installed versions of selected components. Our experiences with a prototype implementation show that the approach has acceptable demands on manual work and computational resources.

“…In case we use Equinox 5 as the target execution platform, all components (business logic components and proxy components) are implemented as OSGi bundles (Spring Dynamic Modules) [30]. In OSGi service platforms, there are two ways to declare and bind services via interfaces (ports): declaring/binding exported services in Spring osgi-context.xml files, or in the source code by overriding the method start of BundleActivator class of OSGi bundle.…”

Abstract. Model-Driven Security (Mds) is a specialized Model-Driven Engineering (Mde) approach for supporting the development of secure systems. Model-Driven Security aims at improving the productivity of the development process and quality of the resulting secure systems, with models as the main artifact. Among the variety of models that have been studied in a Model-Driven Security perspective, one can mention access control models that specify the access rights. So far, these models mainly focus on static definitions of access control policies, without taking into account the more complex, but essential, delegation of rights mechanism. Delegation is a meta-level mechanism for administrating access rights, which allows a user without any specific administrative privileges to delegate his/her access rights to another user. This paper gives a formalization of access control and delegation mechanisms, and analyses the main hard-points for introducing various advanced delegation semantics in Model-Driven Security. Then, we propose a modular model-driven framework for 1) specifying access control, delegation and the business logic as separate concerns; 2) dynamically enforcing/weaving access control policies with various delegation features into securitycritical systems; and 3) providing a flexibly dynamic adaptation strategy. We demonstrate the feasibility and effectiveness of our proposed solution through the proof-of-concept implementations of different componentbased systems running on different adaptive execution platforms, i.e. OSGi and Kevoree.

“…These are clouds whose infrastructure is open for the general public. Google AppEngine (Zahariev, 2009), Microsoft Windows Azure (Hill et al, 2010) and Amazon's Beanstalk (van Vliet, Paganelli, van Wel and Dowd, 2011) are the most well-known and used representatives of this kind of PaaS. Although public clouds are widely used, they present some drawbacks: the developer must adapt every application deployed onto them to their APIs and special requirements, and security and privacy data concerns can render those solutions unfeasible in some contexts.…”

Abstract:Cloud computing has seen an impressive growth in recent years, with virtualization technologies being massively adopted to create IaaS (Infrastructure as a Service) public and private solutions. Today, the interest is shifting towards the PaaS (Platform as a Service) model, which allows developers to abstract from the execution platform and focus only on the functionality. There are several public PaaS offerings available, but currently no private PaaS solution is ready for production environments. To fill this gap a new solution must be developed. In this paper we present a key element for enabling this model: a cloud repository based on the OSGi component model. The repository stores, manages, provisions and resolves the dependencies of PaaS software components and services. This repository can federate with other repositories located in the same or different clouds, both private and public. This way, dependencies can be fulfilled collaboratively, and new business models can be implemented.
