JSP and Servlets

HTTP defines eight methods (sometimes referred to as "verbs") indicating the desired action to be performed on the identified resource. What this resource represents, whether pre-existing data or data that is generated dynamically, depends on the implementation of the server. Often, the resource corresponds to a file or the output of an executable residing on the server. ; HEAD : Asks for the response identical to the one that would correspond to a GET request, but without the response body. This is useful for retrieving meta-information written in response headers, without having to transport the entire content. ; GET : Requests a representation of the specified resource. Note that GET should not be used for operations that cause side-effects, such as using it for taking actions in web applications. One reason for this is that GET may be used arbitrarily by robots or crawlers, which should not need to consider the side effects that a request should cause. See safe methods below. ; POST : Submits data to be processed (e.g., from an HTML form) to the identified resource. The data is included in the body of the request. This may result in the creation of a new resource or the updates of existing resources or both. ; PUT : Uploads a representation of the specified resource. ; DELETE : Deletes the specified resource. ; TRACE : Echoes back the received request, so that a client can see what intermediate servers are adding or changing in the request. ; OPTIONS : Returns the HTTP methods that the server supports for specified URL. This can be used to check the functionality of a web server by requesting '*' instead of a specific resource. ; CONNECT : Converts the request connection to a transparent TCP/IP tunnel, usually to facilitate SSL-encrypted communication (HTTPS) through an unencrypted HTTP proxy.[3]

A gavel is typically used by the chairperson to signal the start or end of a meeting, to call for order, or to bring attention to important points being made. It should be used respectfully and sparingly to maintain decorum and attention during the meeting.

The Servlet 2.3 API consists of two packages: javax.servlet and javax.servlet.http. The base functionality is defined in the javax.servlet package whose classes and interfaces outline a generic, protocol-independent implementation. This means you can use it for non-Web applications, too. The javax.servlet.http interface defines classes and interfaces that are specific to the Hypertext Transfer Protocol (HTTP).

Yes, JSP (JavaServer Pages) and Servlets can be used together in a web application. Servlets handle the business logic and processing of requests, while JSP is used to create the user interface and generate dynamic content. Servlets can interact with JSP pages to pass data and control the flow of the application.

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.

An ASP (Application Service Provider) provides software applications over the internet, while an ISP (Internet Service Provider) provides access to the internet. ISPs offer connectivity services like email, web hosting, and domain registration, whereas ASPs offer software applications for a fee.

Advantages of JSP

1. HTML friendly simple and easy language and tags.

2. Supports Java Code.

3. Supports standard Web site development tools.

Disadvantages of JSP

1. As JSP pages are translated to servlets and compiled, it is difficult to trace

errors occurred in JSP pages.

2. JSP pages require double the disk space to hold the JSP page.

3. JSP pages require more time when accessed for the first time as they are to be

compiled on the server.

Setting and getting session attributes is fairly easy. It is the same in both Servlets and JSPs with one exception. In a JSP, you already have access to the session object, and you do not have to declare it. In a Servlet, you must get the session like this: javax.servlet.http.HttpSession session = request.getSession(); Once you have done that, you can set a session object like this: session.setAttribute("name","value"); To retrieve the value, do this: String foo = (String) session.getAttribute("name"); A couple of things to keep in mind: * The second parameter in the setAttribute method is an Object, not a String. When you retrieve the value, you have to cast it. In the example above, I am casting it to a String. * If you try to perform a getAttribute on a session attribute that does not exist, or was not set, it will return a null. * Session attributes are not available using JavaScript. You can not set or get an attribute in JavaScript. * You do NOT need to do the 'session = request.getSession() in a JSP. It is only necessary in a Servlet.

You can get the ServletContext instance in a servlet by using the getServletContext() method provided by the HttpServlet class, which is the base class for servlets. This method returns the ServletContext object associated with the servlet. For example: ServletContext context = getServletContext();

ServletContext is an interface for communication with the servlet container while PageContext is an object for managing data related to a JSP page. ServletContext is used for application-wide resources while PageContext is specific to a single JSP page.

To create an address book using JSP, you can create a form to input contact information like name, email, phone number, etc. When the form is submitted, you can handle the data in a servlet and store it in a database like MySQL using JDBC. Then, you can retrieve and display this information in the JSP using Java servlets.

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).

The servlet class created in web applications usually extend the javax.servlet.HttpServlet class. The HttpServlet extends the javax.servlet.GenericServlet. These classes contain the basic features that are required to run a web application.

you cant in the main part when you are looking at your profile, but you can refresh pictures by clicking on them and you can refresh your newsfeed

It depends on what kind of tablet.. For an iPad there is a little arrow going in a circle at the end of the box were it shows the website URL or link. It might be the same with android tablets but i am not sure. It usually looks like an arrow rounded into a circle.

JSP stands for Java Server Pages. JSP is an integral part of any j2ee application. It handles the User Interface (UI) layer of any web based application. It has support to execute java code and also can use HTML and java script. The output of a JSP page is usually viewed in a web browser like Internet Explorer or Mozilla Firefox etc.

You can retrieve an image file from a database in JSP by writing a servlet that fetches the image from the database and streams it to the JSP page. The servlet will set the content type to "image/jpeg" or the appropriate image format and write the image data to the response output stream. In the JSP page, you can then display the image by setting the source attribute of the img tag to the servlet URL.

Yes, the JSP tutorial is easy to follow and understand. It tells you what it is doing from start to finish. When the JSP life cycle is complete a screen will pop up and they are finished.
