The invention relates to a constructing method for five-layer structure based on J2EE, belongs to distributed computer application technology field. The invention provides and realizes a five-layer system structure according tot J2EE: constructs five-layer structure which is made up of data layer, data integrating layer, service logic layer, interface control layer and user interface layer from bottom up. The system makes the application program clear, the performance is excellent and easy to be realized, it has a high security, reduces the waste of network resources, at the same time, it can realize component duplex based on the industry standardization, thus the developer without high programming technology can develop high efficient, safe and reliable, extensible manageable distributed industry application program.
