Web Service Adaptation for the Customization of Early Alerts in Agriculture

Early warning systems are designed to inform the largest number of users, such as a country or a region, about a risky situation. However, in specific domains such as agriculture, it is commonly required for these alerts to be more specific according to the crops location and their properties. Consequently, the web services of these systems must be adapted. On the other hand, the enterprise services bus, with its mediation capabilities (such as message transformation and routing), and complex event processing with their monitoring characteristics, can be integrated to meet the adaptation requirements of web services at runtime. This paper presents an improvement for an early warning system for coffee production that, according to the area in which a crop is located and its phenology, manages the adaptation of alerts for coffee rust, based on the integration of an enterprise services bus and a complex events processing.

Enterprise-oriented Communication among Multiple ESBs based on WSNotification and Cloud Queue Model

With the rapid development of Service-Oriented Architecture (SOA), more and more enterprise applications are built on the Enterprise Services Bus (ESB). An Enterprise Service Bus is an open standard, message-based, distributed integration infrastructure. It is called as distributed services, integrated interaction. ESB is responsible for routing of message of all services or components, so when ESB is faced with large-scale messages routing, processing efficiency of messages on ESB will directly affect the processing speed of business processes. From an actual project, a coal mine warning system project, it can be verified, when business process described by BPEL is deployed on ESB, the larger the message load, the slower the processing speed of the process. So, relative to integrated interaction, a distributed interaction is hoped. In this paper, a distributed interaction method is presented to complete business process, while services are deployed on application servers. Multiple ESBs are used to share load pressure that on a single ESB. In this method exchange of data among multiple ESBs is a key problem, if exchange can’t be supported, distributed interaction would not be implemented among multiple ESBs. To solve this problem, we propose an enterprise multi-ESBs communication method, on the basis of WS-Notification specification and cloud queue model, we design and implement Web Service notification broker and Subscribe Request Queue cloud service that supports real-time communication among multiple ESBs. Through theoretical analysis and practical application, our method shows better processing efficiency of business process.

Research and implement of SOA-oriented enterprise services bus

For the quickly growing requirements of information sharing and business integration in enterprise,it tends to use SOA architecture to integrate enterprise applications because enterprise service bus can shield the heterogeneous enterprise applications.Current products of SOA-oriented Enterprise Service Bus(s-ESB)can mainly offer Web services container but unified adapter mechanism to integrate some kinds of enterprise applications.It restricts the availability and scalability of s-ESB.In this paper,it firstly brought forward a new SOA-based enterprise application integration environment which clarified the status and function of s-ESB in constructing Web services-based application supporting platform.Then,it presented an architecture for s-ESB,and then analyzed some key technologies including protocols adaptation,service adaptation and common services etc.At last,s-ESB is proved to be feasible and effective by prototype system.

Events and service-oriented architecture: The OASIS Web Services Notification specification

The OASIS Web Services Notification (WSN) family of specifications defines a standard interoperable protocol through which Web services can disseminate events. We present here a summary of three WSN specification documents that are currently available: WS-Base Notification, WS-Topics, and WS-Brokered Notification. We conclude with a brief discussion on the use of the notification pattern in the Enterprise Services Bus, a service-oriented infrastructure for mediating requests among cooperating Web services.
