Strategies for integration of a non-OO EIS and the J2EE framework

Proceedings 26th Annual International Computer Software and Applications, Feb 1, 2002

A unique situation of this project is that the COTS part and the J2EE components are designed at the same time. The designers have to make more choices than those in the cases of wrapping legacy systems. In addition to performance and scalability, we have paid attention to the manageability of COTS product upgrading. In doing so, we have recommended five integration design strategies, among which the application-level data replication strategy is very effective.

This framework can support a number of rich features such as resumable client applications, the Single-Request/Multiple-Response (SRMR) message exchange pattern, intra-enterprise user and terminal mobility, and flexible interaction styles for client applications to communicate with asynchronous Web services.

Self-Adaptive Load Sharing for Distributed Image File Processing

By taking advantage of this property, we have implemented a distributed image file processing (DIFP) program on an Ethernet network and have illustrated substantial speed-up. A master/slave model for DIFP is proposed, which is based on a self-adaptive load sharing protocol -- "dispatching by request ". Issues in design and implementation of DIFP systems including load sharing, data partitioning, job distribution, concurrent file access, and error handling have been addressed. Key words Image processing, load sharing, distributed systems. 1. Introduction Digital image file processing (DIFP) is often time consuming due to a large data volume or intensified calculations. Parallel image processing 1 based on nCUBE, iPSC/2 and transputers has demonstrated a great deal of speed-up. However, the implementation of pa...

Achieving interoperability for integration of heterogeneous COTS geographic information systems

On the other hand, deploying heterogeneous GIS software has the tendency to form fragmented data sets and to cause inconsistency. Data consolidation is an effective way to preserve data integrity. To accomplish this, we must achieve interoperability between

Empirical studies of a decentralized regression test selection framework for web services

Proceedings of the 2008 workshop on Testing, analysis, and verification of web services and applications - TAV-WEB '08, 2008

Safe regression test selection techniques are often employed in conjunction with regression testing to reduce the associated costs of testing without reducing the level of confidence provided. In a previous work, a framework which automates the safe regression test selection and regression testing processes was developed in a decentralized, end-to-end manner. This paper reports an empirical study of the framework designed to compare the cost of performing the proposed approach and running the selected tests with the cost of running all tests without performing a selection step. The results indicate that the framework can be effective in reducing the costs of performing regression test selection.

Applying Safe Regression Test Selection Techniques to Java Web Services

Although regression testing is a major component of most major testing systems, it has only begun to be applied to Web services. The majority of these tools and techniques focus on test case generation, ignoring the potential benefits of regression test selection. Regression test selection (RTS) is a mechanism for reducing the number of tests that must be rerun to ensure some level of confidence. Safe RTS techniques add an additional constraint, namely no modification revealing tests are left unselected. Since Safe RTS techniques involve white-box testing, they cannot be directly applied to Web services. We will propose a mechanism for applying a safe RTS technique to Java-based Web services in an end-to-end manner using a code transformation-based approach. Additionally, we will provide implementation details as well as an example.
