How do you Pass Control From One JSP Page to Another

by

Use the following ways to pass control of a request from one servlet to another or one jsp to another.

  • First is RequestDispatcher object‘s forward method to pass the control.
  • Second is response.sendRedirect method.

In Advanced Java, when you want to pass control from one JSP (JavaServer Pages) page to another, you typically use mechanisms like:

  1. Request Dispatching: You can use RequestDispatcher to forward or include the content of another JSP page. The RequestDispatcher is obtained from the ServletRequest object.
    java
    RequestDispatcher dispatcher = request.getRequestDispatcher("secondPage.jsp");
    dispatcher.forward(request, response);

    This method transfers control to the target resource (in this case, “secondPage.jsp”) and the client is not aware of this transfer; the browser’s address bar does not change.

  2. Redirect: You can use response.sendRedirect() to redirect the client’s browser to another page.
    java
    response.sendRedirect("secondPage.jsp");

    This method sends a temporary redirect response to the client, and the client’s browser will make a new request to the redirected page. The URL in the browser’s address bar changes to the new page.

Choose the appropriate method based on your specific requirements. If you want to keep the URL unchanged and transfer control internally, use RequestDispatcher. If you want to change the URL in the browser and create a new request, use sendRedirect().
