Communication between the servlet and the JSP

Js|servlet The following code fragment demonstrates a servlet that illustrates (instantiates) a bean and initializes it with the form data sent by the browser. The bean is then added to the request, which is sent to the JSP page (bean1.jsp), which is obtained through the request and processed further.

public void DoPost (HttpServletRequest request,
HttpServletResponse response) {

try {
Govi. Formbean f = new Govi. Formbean ();
String id = request.getparameter ("id");
F.setname (Request.getparameter ("name"));
F.setaddr (Request.getparameter ("addr"));
F.setage (Request.getparameter ("Age"));
Use the ID to compute
Additional Bean properties like info
Maybe perform a DB query, etc.
// . . .
F.setpersonalizationinfo (info);
Request.setattribute ("Fbean", f);
Getservletconfig (). Getservletcontext (). Getrequestdispatcher
("/jsp/bean1.jsp"). Forward (request, response);
catch (Exception ex) {
. . .
}
}

When it is first executed from the default request range of the Usebean operation, that is, the Fbean can be processed in the bean1.jsp of the JSP file.

<jsp:usebean id= "Fbean" class= "Govi". Formbean "scope=" Request "/>
<jsp:getproperty name= "Fbean" property= "name"/>
<jsp:getproperty name= "Fbean" property= "addr"/>
<jsp:getproperty name= "Fbean" property= "Age"/>
<jsp:getproperty name= "Fbean" property= "Personalizationinfo"/>
