NUIX系统下实现报表终端打印

目前有相当数量的计算机用户已选用UNIX／XENIX操作系统支持FOXBASE开发管理软件，由于UNIX／XENIX操作系统与DOS操作系统不同，特别是与终端相连的打印机不能直接输出有关报表内容，即不能实现终端打印，给广大用户带来诸多不便，且造成计算机资源的很大浪费。我们在实践中，通过以下办法实现了终端打印问题。方法一UNIX／XENIX多用户多任务操作系统中创建了“管道”（ripe）的概念（即一个程序的输出为另外一个程序的输入），通过管道的原理可以实现终端打印。假设第一个程序为用户的报表输出程序，后一个程序为其它高级语…

A framework for table driven testing of Java classes

With the advent of object‐oriented languages and the portability of Java, the development and use of class libraries has become widespread. Effective class reuse depends on class reliability which in turn depends on thorough testing. This paper describes a class testing approach based on modeling each test case with a tuple and then generating large numbers of tuples to thoroughly cover an input space with many interesting combinations of values. The testing approach is supported by the Roast framework for the testing of Java classes. Roast provides automated tuple generation based on boundary values, unit operations that support driver standardization, and test case templates used for code generation. Roast produces thorough, compact test drivers with low development and maintenance cost. The framework and tool support are illustrated on a number of non‐trivial classes, including a graphical user interface policy manager. Quantitative results are presented to substantiate the practicality and effectiveness of the approach. Copyright © 2002 John Wiley & Sons, Ltd.     

Bayanihan: building and studying web-based volunteer computing systems using Java

Project Bayanihan is developing the idea of volunteer computing, which seeks to enable people to form very large parallel computing networks very quickly by using ubiquitous and easy-to-use technologies such as web browsers and Java. By utilizing Java’s object-oriented features, we have built a flexible software framework that makes it easy for programmers to write different volunteer computing applications, while allowing researchers to study and develop the underlying mechanisms behind them. In this paper, we show how we have used this framework to write master-worker style applications, and to develop approaches to the problems of programming interface, adaptive parallelism, fault-tolerance, computational security, scalability, and user interface design.     

Developing dynamic‐reconfigurable communication protocol stacks using Java

This paper proposes the development of a dynamic‐reconfigurable protocol stack, which allows the programmer to create, to remove, and to replace protocol modules during their operation. Moreover, this protocol stack also aims to preserve the module state, such as the data structures that manage the existing connections. To achieve these goals, a Java‐based component framework is developed so that the programmers are able to implement their components under the proposed framework. This framework can dynamically reconfigure the components at a safe period and can help the components transfer their states, and the dynamic reconfiguration is transparent to the user application running on top of the stack. To demonstrate the component framework, a TCP component is implemented. While maintaining active connections for the user application, the TCP component is able to be dynamically replaced by another version. Copyright © 2005 John Wiley & Sons, Ltd.

Klava: a Java package for distributed and mobile applications

Highly distributed networks have now become a common infrastructure for wide‐area distributed applications whose key design principle is network awareness, namely the ability to deal with dynamic changes of the network environment. Network‐aware computing has called for new programming languages that exploit the mobility paradigm as a basic interaction mechanism. In this paper we present the architecture of KLAVA , an experimental Java package for distributed applications and code mobility. We describe how KLAVA permits code mobility by relying on Java and present a few distributed applications that exploit mobile code programmed in KLAVA . Copyright © 2002 John Wiley & Sons, Ltd.
