User profile information is stored in a parameter named servlet bean to retrieve from the Profile Repository all user profiles that meet the targeting rules you specify—for example, all users who live in Boston and are registered members of your site.

Should I give reference to old html page to edit or new page or .. I know I haven't followed MVC structure but I wanted to do whole coding in single page so waiting for help..

The three classes are used to show easy implementation of Spring IOC using Setter Method, Constructor argument passing and @annotations methods.We have created the following files for this bookstore example: $ find ../Web Content/WEB-INF/pages/Book Form ./Web Content/WEB-INF/pages/Book Listing ./src/META-INF/Needed for Java EE dependency injection (CDI) ./src/com/bookstore/Domain/model object ./src/com/bookstore/Book Repository Repository implementation using Java collections (just for testing) ./src/com/bookstore/Book Interface to Book Repository so we can swap it out with JDBC, JPA, JCache and Mongo DB version later ./src/com/bookstore/web/Book Editor Servlet that loads Book (do Get) form and handles Book form submissions (do Post).also you need to provide a mapping for "/show Kwh" in your checkout the code in this link tutorialspoint.com/servlets/Either you put all data that you need to post back upon submit into form fields and browser sends it, or you use some javascript like j Query to manipulate your html table's DOM, extract data on the clientside and send it via ajax request in form of JSON or XML to be parsed serverside. Since data in the table originates from the same server that processes response, it would be sufficient to respond with a set of row identifiers, by which the server would recognize full row data.You can then set the value of The following code example shows how to use a Table Info component to render a simple table.Later sections show how to build more tables, where the user can change the columns on which the table is sorted. I am developing a e-commerce college project, here i add the items in the cart(a div tag in the jsp page) via servlet by creating sessions, flow control: shopping jsp (when user wants to add an item in the cart) -- cart servlet(which is used to add items in the arraylist and show them in the shopping.jsp's div tag it also sets the total purchase amount in the session variable "totalpurchase") now after that user wants to proceed to checkout, here i use the onclick event to check the minimumshopping amount must be less than the totalpurchase (totalpurchase which i had setted in the session),but my jsp page is unable to rechognise the updated value of the totalpurchase, yes, if i reload the page, it rechognises the new updated value of the totalpurchase? please helpnow after that user wants to proceed to checkout, here i use the onclick event to check the minimumshopping amount must be less than the totalpurchase (totalpurchase which i had setted in the session),but my jsp page is unable to rechognise the updated value of the totalpurchase, this onclick handler, sends the hidden parameters like totalpurchase and minimumorder (amount) to javascript, which checks that totalpurchase must not be smaller than minimumorder to proceed to final checkout.. The hidden value obviously can only reflect what was put into the cart before the current page was displayed - you'd need to update that with whatever was added to the cart on the current page. Or are you saying that the hidden field does not have the correct value to begin with? actually i have a jsp file contains cart (as a div tag) and many other div tags in which the item to be added in the cart are placed.., now when user clicks on the item , in the backend the control will go to the servlet in which session is created and synchronized then the control moves to other servlet which adds the item in the arraylist (Backend - cart ) and show those items in the jsp page's div tag(UI - cart) and also set a session variable,value (totalpurchase) , UI (JSP file) now after this, when user saw the item is added in the cart, he wants to proceed to final checkout, when user clicks on the final checkout button(after that div tag in the JSP page), i want the ( updated ) value of that session variable ( totalpurchase ) , Error: totalpurchase value is "0" , that is, it is not changed according to the new value updated by the servlet.but i want it to rechognise the updated total purchase value, without reloading he jsp page.. and yes, if i refresh my page at this stage, then it catches the correct value..so you will need to create a separate servlet class and use jdbc code there to persit the data in db.you can set the table attribute in your jsp and fetch inside servlet.
