To create a controller for a JSP page, you typically use a servlet that handles incoming HTTP requests. This servlet processes the request, interacts with any necessary business logic or data models, and then forwards the request and relevant data to the JSP page using a RequestDispatcher. You can set attributes in the request scope to pass data to the JSP, and finally, return the response by calling request.getRequestDispatcher("yourPage.jsp").forward(request, response);
. This separation of concerns helps maintain a clear architecture between the presentation layer and business logic.
how to create a master page in java
In JSP, the extends attribute is used in the <jsp:directive.page> tag to specify a superclass for the JSP page. This allows the JSP to inherit methods and properties from the specified Java class, enabling code reuse and organization. By extending a class, you can implement custom functionality or override methods, enhancing the capabilities of your JSP. For example, you might use extends to create a base page class that handles common logic for multiple JSP files.
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
There is no limit as such. You can use one or more Page Directives in a JSP but you cannot have duplicates
how to create a master page in java
In the context of JSP, the Model-View-Controller (MVC) pattern can be implemented by having the JSP act as the View to display data from the Model (usually Java objects) and the Controller can be represented by servlets or Java classes that handle business logic and interact with the Model. The JSP page is responsible for displaying the data provided by the Controller, maintaining a separation of concerns between the presentation (View) and business logic (Controller).

Yes you can. Use the below line in your JSP page to accomplish it. <%@ page session="false" %>

Yes. You can embed spreadsheets, pdfs and word documents in a JSP Page

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.
MVC refers to Model View Controller architecture. Jsp pages are the view part of the MVC architecture...
