The Research of Ajax Technique Application Based on the J2EE

This paper focuses on the researches of Ajax technique and its application based on J2EE. The advantage and the disadvantage of using Ajax technique are analyzed through the experiments. Ajax technique is a comprehensive utilization of a set of Web2.0 core technology. The difference from the traditional Web working module is that Ajax technique adopts asynchronous to send request to server. The advantage is to update the response data locally on the current page, so that user does not experience updating interaction. However, when the amount of response data increases, the burden on server also increases. Thus, the waiting period for response data is extended at users. Ajax technique only adapts to the Web application programs with small amount of data transfer and frequent interaction. Another feature of Ajax technique is that the Browser's "backwards" function is impacted.
