JSP stands for Java Server Pages. It is the face of any web application. I.e., the stuff you see on a web page can be JSP contents. The JSP uses the features of both Java and HTML to display dynamic contents on a web page. It interacts with Servlets in a MVC architecture to provide the power to display dynamic and advanced data on any given web page.
JSP actions are XML tags that direct the server to use existing components or control the behavior of the JSP engine. JSP Actions consist of a typical (XML-based) prefix of "jsp" followed by a colon, followed by the action name followed by one or more attribute parameters. There are six JSP Actions: < jsp : include / > < jsp : forward / > < jsp : plugin / > < jsp : usebean / > < jsp : setProperty / > < jsp : getProperty / >
There is no limit as such. You can use one or more Page Directives in a JSP but you cannot have duplicates
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.
To move data from a servlet to a JSP, you can use the request object to set attributes. You can call request.setAttribute("attributeName", data) in the servlet to store the data. Then, use request.getAttribute("attributeName") in the JSP to access that data. Finally, forward the request to the JSP using a RequestDispatcher, like request.getRequestDispatcher("yourPage.jsp").forward(request, response).
The correct term is "JSP Implicit Objects" In any JSP Page, there are a bunch of implicit objects that are available for the programmer to use. It contains a variety of information that can be used to display stuff on the page. The following JSP Implicit Objects that are available for a programmer. • request • response • out • session • config • application • page • pageContext
Firstly, this is wrong question. The right one would be WHEN should you use PHP, not JSP? or, WHEN should you use PHP and WHEN JSP?

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

No. JSP and Swings are two contrasting Technologies and cannot be used in the same application. And - JDBC can be used with both types of applications that use either JSP or Swings
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.
You can dynamically identify the JSP file in a servlet by using the request URL or request parameters to determine which JSP to forward the request to. You can also store necessary information in session attributes or external configurations to help determine the appropriate JSP to display. Finally, you can use a servlet mapping or URL pattern to route requests to different JSP files based on the URL.

The tag lib directive is used in JSPs to include tag libraries. < % @ taglib uri=http://www.myCompany.com/myTagLibrary prefix="myLibrary" % > This is how you include a tag library into a JSP
