Abstract

This article describes an idea about how to invoke web service asynchronously in a batch mode. Here we bring up two concepts: data source template and data source instance. Data source template is an abstract description of web service. Data source instance is a collection of the parameters for particular data source templates. The system could leverage the data source template and data source instance to invoke web service in a batch mode at customizable frequencies.

System and Method for Asynchronous Web Service Invokation (Batch Mode)

Web Service/SOA technology is a natural solution for data integration. Most of Web Services toolkits are only able to invoke specified web service by parsing WSDL during development and generating the web service client stub.In some enterprise systems,during development, it's impossible to predict all web services the system is going to incorporate in production. Therefore, we must enable administrator to add any customized web service into system at runtime without programming. In order to accomplish this kind of integration, we bring up two concepts: data source template and data source instance.

The data source template is a description of web service. It contains almost all the information which is used to invoke the web service except some necessary parameters. The data source template is created by system administrator. The data source instance is a collection of the parameters which are missed in data source template. It is created by end user. One data source template can have many different data source instances. The system could leverage the data source template and data source instance to invoke web service in a batch mode at customizable frequencies.
