Web server in the face of visits JSP page request, the first implementation of the procedures of, and then together with the results of the implementation of JSP documents in HTML code with the return to the customer. Insert the Java programming operation of the — 46 — database can be reoriented websites, in order to achieve the establishment of dynamic pages needed to function.
