With the advancement of the national information construction, the informationconstruction of many enterprises has reached certain achievements, but all these enterprisesgenerally exist some problems such as the low using efficiency of information, "isolatedinformation island", repeated building, resources waste and so on, which are increasinglyprominent. So the application integration technology to enterprise has become the keytechnology to solve these problems. This paper introduces the concept and different levels of application integration toenterprise, summarizes and refines them, and on which to base the overall framework of theapplication integration to enterprise. According to this framework and according to theorder of database -application -gateway ,this paper divides the application integrationinto data integration, application and flow integration, gateway integration, discusses theinterrelated application integration technology of each level in detail, and comparativelyanalyzes the different technology which uses for the identical level.This paper studies how to solve the problem of the gateway integration to enterprisewhich is based on the J2EE technology, combining a practical project which I did in acompany.
