request.getAttribute() is used on the Server side Java code to get values submitted from the form onto the Servlet or other java classes request.getParameter() is used on the JSP page to get values sent by the servlet and display it in the jsp page
There are several ways to use an HTML button to go to a web page. You can keep it simple. This example uses "page.jsp" in the same directory as your HTML page for your target location. You can use the following code:
Yes you can. Use the below line in your JSP page to accomplish it. <%@ page session="false" %>
The implicit objects in a JSP page are:requestresponsepageContextsessionapplicationoutconfigpage
The 3 life cycle methods in a JSP page are:jspInit() - Called when the JSP page is initializedjspService() - Called everytime a request/response is received/submittedjspDestroy() - Called when the JSP is no longer required
application
Yes. You can embed spreadsheets, pdfs and word documents in a JSP Page
There is no limit as such. You can use one or more Page Directives in a JSP but you cannot have duplicates
You can use the errorPage attribute of the page directive. If this attribute is defined in a JSP page, when a run time exception is encountered, the control will be transferred to this JSP page. This error page can access details of the Exception from the request and use it to display a logical message to the user.
A JSP page consists of HTML markup mixed with Java code enclosed in scriptlet tags (<% %>), expression tags (<%= %>), declaration tags (<%! %>), and directive tags (<%@ %>). During execution, the JSP engine translates the page into a servlet, which can dynamically generate content to be sent to the client. JSPs allow for the separation of presentation and business logic in web applications.
The Page Directive is one of the important components of any JSP Page. It can help us define page specific properties like Buffer size or location of an error page etc A JSP page, and any files included via the include directive, can contain one or more page directives but no duplicates. The JSP container will apply all the attributes to the page. The position of these page directives is irrelevant, but it is good practice to keep them together at the top of the page. (So that we can identify them easily)
