Hi Sadia, For example I want to create a simple book site that will display a list of books:
1. Create my Book.java bean (http://pastebin.com/fe232e2b) 2. My home page which is index.jsp will have a link to the book list which is a link to a servlet (BookServlet.java) that will create the book list for me (usually you do this with a data source but we'll just hardcode the list in this case) and then the servlet will dispatch the request to a jsp(bookCatalog.jsp) and the jsp will display the book list. ( http://pastebin.com/f4566c599) 3. So in BookServlet.java we've added the bookList object to the session and we can get it in bookCatalog.jsp using EL and display it using JSTL(forEach) as well. (http://pastebin.com/f3f13befd) But again since you missed out on these concepts I strongly recommend going back to EL and JSTL. The codes assume you know what to import. They may have some errors as I just wrote it on pastebin but it should give you the idea.
