Thus, the reengineering of object oriented software becomes more and more important as the number, age and size of such legacy systems grow. A key issue during reengineering is the identification and location of design problems which prevent the efficient further development of a system. Up to now this problem area has not been sufficiently supported, either by methods, or by tools. We present a technique for analyzing legacy code, specifying frequent design problems as queries and locating the occurrences of these problems in a model derived from source code. We present our experiences with a tool set which we implemented to support this task by automatically analyzing a given system and detecting the specified problems. We applied our tools to check violations of a number of well known design rules in existing source code taken from several case studies, both from industrial and academic fields. These experiments showed that the task of problem detection in reengineering can be automated to a large degree, and that the technique presented can be efficiently applied to real world code.","PeriodicalId":147966,"journal":{"name":"Proceedings of Technology of Object-Oriented Languages and Systems - TOOLS 30 (Cat.

When to trust mobile objects: access control in the Jini/sup TM/ Software System 何时信任移动对象:Jini/sup TM/ Software System中的访问控制

If this convergence is to be implemented successfully, then a shared model for reliable service provision is required. The recently released Jini/sup TM/ Software System (1.0) is an attempt to meet this requirement through object orientation. Based entirely upon existing Java/sup TM/ 2 technology, Jini is a set of protocols and programming models for peer-to-peer service provision using downloaded code and remote method invocation. The paper examines the way in which the Jini Software System will be used. It shows that the existing mechanisms for access control and secure operation provided by Java may prove inadequate in a Jini environment: a Jini enabled device will be vulnerable to attack from its peers. Similar problems may be encountered in other related technologies, such as Enterprise Java Beans. An account of the Jini technology is followed by an exploration of the inadequacies and vulnerabilities; concrete examples are provided to illustrate the possible attacks. The paper ends by showing how the existing specification may be enhanced to produce a secure system without significantly reducing either functionality or flexibility.","PeriodicalId":147966,"journal":{"name":"Proceedings of Technology of Object-Oriented Languages and Systems - TOOLS 30 (Cat.

The development process is often distributed across time and space and takes place within and between specialized workgroups. This necessitates finding appropriate answers to questions related to division of labor, to communication, and to coordination and cooperation in the planning, development and maintenance of software systems. Development environments that explicitly support group work are an important prerequisite for the production of high quality software systems. Most of the software development environments in use today support primarily technical aspects and have shortcomings in the area of organizational support. The paper describes a model for cooperative work processes in software projects and a corresponding development environment that provides balanced support for both organizational and technical aspects of software development. The work toward the conception of the model and the implementation of the development environment have been completed, and the evaluation of the proposed approach has begun. Experience to date with using the developed environment confirms the assumption that the cooperative, cluster oriented development improves both productivity and quality. The presented approach excels primarily in its easily understandable model, the intuitive usability of the tools and the comprehensible presentation of process- and product-related information.","PeriodicalId":147966,"journal":{"name":"Proceedings of Technology of Object-Oriented Languages and Systems - TOOLS 30 (Cat.

Distributed programming is constantly evolving into a very realistic technology which enhances systems integration through interoperability, adaptability and flexibility. However such advantages, coupled with performance, can only be gained by the proper analysis and design of the systems or frameworks in question. A critical examination would reveal that such a framework can be made realistically possible through the usage of object oriented methods combined with the elegance of design patterns and the advances made in CORBA technology. The described environment will ensure consistent creation of protocols and other such similar services through reusable object oriented components communicating over a heterogeneous network while addressing certain shortcomings, such as ensuring asynchronous communication remaining guaranteed and providing native event and message based features without resorting to CORBA based messaging and event services. It also attempts to shield the developer from network specific issues by providing a more generic but very consistent technique to interface to the underlying services. Two areas in which such a framework can be employed are described within the Intelligent Networks realm to illustrate the available methods and practices.","PeriodicalId":147966,"journal":{"name":"Proceedings of Technology of Object-Oriented Languages and Systems - TOOLS 30 (Cat.
