The Design And Implementation Of Instance Integrated Office System Based On J2EE

The use of Integrated Office System is expanding rapidly as the need for expanding Internet and e-Government. So how to develop enterprise applications rapidly and effectively becomes more and more urgently.Multi-tiers application solutions such as J2EE have satisfied the demand perfectly. J2EE is a mature enterprise application solution and this is approved by the fact. J2EE has a lot of supporters and has been applied in many enterprise cases in oversea markets. And it becomes more and more popular in China. At the same time, JMS message service technology, workflow technology and full-text retrieval technology develop rapidly. These make constructing a cross-platform message, constructing a key service or retrieving data easy.In this paper, J2EE architecture and many key technologies inside have been studied. The core service components: message service component, workflow component and full-text retrieval component, are introduced in detail.Message service component provides message service by JMS and MDB. Workflow component presents a framework of a relationship-based lightweight workflow engine. It consists of three components, namely: organization model, information model and control model. Full-text retrieval component bases on Oracle Text of Oracle Database. Oracle Text has powerful full-text retrieval ability in Oracle Database. We can construct complex file management system on it.
