Problems solved by technology

Since the J2EE Web presentation layer lacks the support of a mature component framework, the RFID middleware Web presentation layer does not have flexibility, customization and scalability
And with the increasing scale and complexity of the RFID middleware Web presentation layer, the disadvantages caused by the lack of effective component framework support become more and more obvious

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] figure 1 It is a schematic diagram of the process structure of the component dynamic perception model based on OSGi DS. The model includes four modules: component registration center, service component runtime, J2EE framework provider component and J2EE framework consumer component.

[0024] The specific workflow of the model is as follows:

[0025] 1. First define a Java interface that declares the consumer of the J2EE framework. Each J2EE framework consumer component must define a J2EE framework consumer component to publish a service that implements this interface, and take the information that needs to be passed to the J2EE framework (such as the path of the configuration file) as the attribute of the service. The xml form of the J2EE framework consumer component is described as follows:

Abstract

The invention provides a dynamic sensing model of a member and application thereof to a Web presentation layer of RFID middleware. The sensing model comprises a member registration center, a service component run time, a J2EE frame provider component and a J2EE frame consumer component. The member registration center is used for caching registration or cancellation information of the member, the service component run time is used for realizing registration or cancellation of an agent component, the J2EE frame provider component is used for dynamically collecting and maintaining registration or cancellation information of the component from the member registration center for a host member, and the J2EE frame consumer component is used for realizing dynamic registration or cancellation of the host member in the member registration center.

Description

technical field [0001] The invention relates to a componentization method of a J2EE Web presentation layer and its application, in particular to the application of the RFID middleware Web presentation layer. technical background [0002] With the rapid development and wide application of radio frequency identification technology (Radio Frequency Identification, RFID), RFID has been closely integrated with people's daily life. Both civilian and military products have put forward higher and higher requirements for RFID applications, mainly including Key features such as flexibility, customizability, and scalability. [0003] RFID middleware extends enterprise-level middleware technology to the RFID field, and is the core technology of the RFID industry chain. The RFID middleware Web presentation layer is the interface between the user and the RFID middleware, and the interface for the user to work. Key operations such as RFID middleware operation management, reader control a...
