Objects should team-up in order to co-operate and jointly deliver complex behaviors. Objects play specific roles within a given Team. line Context based dispatch Object behavior is controled by the currently active context of execution. Contexts are reified into Team instances, which may be used to mediate between roles and maintain state of the collaboration. line Modules larger than classes On the road to re-use of modules larger than classes two approaches compete: frameworks and components. For many applications white box frameworks are too fragile and black box components to rigid. Object Teams provide a middle road which balances encapsulation and adaptability. line Key Features of Object Teams * Weaving of aspect code into existing classes (no source code needed). * Teams are modules that encapsulate the interaction of a set of role objects. o Teams can be type-checked in a modular way. o Roles are automatically managed by their enclosing Team instance. * Teams can be refined using inheritance. o Collective refinement of role classes. o Team refinement realizes type-safe covariance of role signatures. * Teams are instantiable first class entities. o Teams are aspects that can be activated/deactivated at run-time. o Roles may refer to their enclosing Team. * Explicit connectors bind an abstract Team definition to a base package. o Binding happens a-posteriori, i.e., no modification in the base package is required. o Team binding is specified in a declarative style. o Bindings may specify different kinds of adaptations. * Object Teams require a minimal number of new language constructs to be learned for a maximum of modularity and composability.

The main purpose of ztest is to put constraints on the code structure of java programs. It can and should be used to specify an architecure by putting constraints on class dependencies. The architecture can be reused by reusing the test. ztest scans the bytecode of class files in directories, jars, wars, ears and computes a dependency graph. You can query this dependency graph and define the architecure by specifying valid dependencies and rejecting invalid ones. ztest comes with a dependency-test (ZDependencyTest) with which you can define sets of classes and the allowed dependencies between them. The class sets are defined by filtering the nodes of the dependeny graph.

It provides dependency analysis, metrics, design rule checking and impact analysis. Define your desired architecture model and check consistency with the implementation. jmove offers a framework and an extendable set of tools to ease the understanding of the design and architecture of software systems and to provide support to control the software from this point of view. It is based on a model centric approach which allows to analyze different kind of sources like source code and byte code.

EasyBeans main goal is to ease the development of Enterprise Java Beans. It uses some new architecture design like the bytecode injection (with ASM ObjectWeb tool), IoC, POJO and can be embedded in OSGi bundles or other frameworks (Spring, Eclipse plugins, etc.). It aims to provide an EJB3 container as specified in the Java Platform Enterprise Edition (Java EE) in its fifth version. It means that Session beans (Stateless or Stateful), Message Driven Beans (MDB) are available on EasyBeans. The new persistence layer used by EJB 3.0 is now called Java Persistence API (or JPA). It replaces the CMP (Container Managed Persistence) model used by EJB 2.x. The default persistence provider used in EasyBeans is Hibernate Entity Manager or Apache OpenJPA but other JPA providers have been tested like for example Oracle TopLink Essentials.

Simply put, Agile Modeling (AM) is a collection of values, principles, and practices for modeling software that can be applied on a software development project in an effective and light-weight manner. As you see in Figure 1 AM is meant to be tailored into other, full-fledged development methodologies such as XP or RUP, enabling you to develop a software process which truly meets your needs. The techniques of AM, in particular Agile Model Driven Development (AMDD), the lifecycle for which is depicted in Figure 2, enable you to scale agile software development to very complex situations.

Stylebase is a reuse repository for architectural models and design patterns and it assists in applying quality-driven architecture design into software engineering. The tools are extensions to Eclipse, the most widely-used open source integrated development environment. We believe that Stylebase for Eclipse helps to improve the quality of software products and also increases reuse and information sharing in local and distributed development teams.

It supports parsing of arbitrary models, and a language family to check and transform models as well as generate code based on them. Supporting editors are based on the Eclipse platform. OAW has strong support for EMF (Eclipse Modelling Framework) based models but can work with other models, too (e.g. UML2, XML or simple JavaBeans) At the core there is a workflow engine allowing the definition of generator/transformation workflows. A number of prebuilt workflow components can be used for reading and instantiating models, checking them for constraint violations, transforming them into other models and then finally, for generating code.
