Research On Middleware Of Electronic Application Realm

The E-GOV is system engineering. It is important realm of the national information-based construction. It is important means that props up the E-GOV to standardize. Currently, the construction of the E-GOV of our country still has many shortages. Comparing to the E-GOV of abroad it still has the very big margin. These shortages mainly include quantity of the E-GOV,updating information,interacting with customer. At the aspect of the development of the E-GOV, redevelopment phenomenon still exists. Therefore adopting standard module development is a direction of the E-GOV construction. The electronics application is a basic function module of the E-GOV system.This paper focuses on the technology of middleware development, I try to adopt workflow middleware technology to develop the electronics application. I am for adopting the standard module development E-GOV system to carry on trying once.This topic aims at the electronics application module within the E-GOV and puts forward the workflow solution. According to the request of the workflow realization, I analysis the electronics application domain and puts forward the electronics application domain model. On the basis of the electronics application domain model, I design the workflow middleware of the electronics application.The design of the workflow middleware matches the workflow model that was put forward by WFMC. I choose the XPDL as the process description language. I choose the workflow key technique of the piece the workflow middleware of the electronics application. I adopt the technique of EJB to implement the workflow engine, adopt the JMS technique to carry out the technique in the task sequence management machine. At last, I pack the electronics application middleware, and elaborated how to gather the workflow middleware with E-GOV systems. The electronic application workflow middleware that this paper puts forward gives the solution for the construction of the E-GOV. Make use of in the center a technique can change the demand of the development according to the society, dynamic state development business, high quantity, set up the E-GOV system high efficiency.
