What is the Expansion for JSP?
JSP stands for Java Server Pages. They are used in Java Enterprise applications that are created to be used on web pages. The JSP page acts as the user interface for the enterprise application.
Can xml be created using jsp?
Yes, JSP can output XML. To do this, simply output XML instead of HTML inside the JSP. A good idea is to start the JSP with a <%@page contentType="application/xml; charset=UTF-8" %> header, so that the correct contentType gets set.
What is the expansion of jsp?
JSP stands for Java Server Pages. Java Server Pages have become an integral part of any J2EE application. They are used extensively because they can combine the features of HTML and Java. The difficulty level of JSP is half-way between HTML and pure Java. For simple tasks like displaying the current date, you write a normal HTML page and add only a small amount of Java as a scriptlet. For big tasks like processing a shopping cart, you use JSP as the mediator between the Web form and a component (Ex: Servlet) that has all the processing logic. CGI, Perl, Active Server Pages etc were all the predecessors of Java Server Pages. Am not saying that the JSP Technology was built based on these technologies but it is safe to say that, the JSP Technology was created to overcome many of the shortcomings in the above mentioned technologies. Though the ASP technology is a web server scripting champion and is used very widely, the only problem is the Runs only in Windows Attitude of the technology. Unlike ASP, JSP has equivalent if not better features and can run in any environment making it an invaluable tool for enterprise application developers who don't want to be tied to the limitation of the system running only in Windows. Not only does JSP run on all major platforms, but the JavaBeans used by these JSPs run on all major platforms as well. JSP competes directly with ASP. In fact, you would be forgiven if you thought it was a copy. Sun took the same approach to JSP as it did with Java. Sun borrowed the syntax of its best competitor (ASP for JSP and C++ for Java) tweaked it a little, but built everything under the hood from scratch. Java syntax comes from C++, but it works on all platforms with no portability issues like C++ for the developer. Similarly, the JSP structure comes from ASP. The look and feel, and even some syntax is the same. However, ASP primarily uses Microsoft's versatile VBScript, while JSP uses the more powerful and portable Java and JavaScript.
Can you override the life cycle methods of a JSP?
You cannot override the jspService() method but you can override the jspInit() and jspDestroy() methods

What is difference between custom JSP tags and beans?
They are two totally different concepts and are entirely different when compared to one another. The similarity is that - they both are used by JSP Pages to enhance the features and functionality of the JSP Technology
What are jsp actions?
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 / >
What is tag lib directive in jsp?
The taglib directive in JSP is used to declare a set of custom tags defined in tag libraries that are used in the JSP page. It must be placed at the top of the JSP page and specifies the location of the tag library descriptor (TLD) file and the prefix to use when referencing the custom tags within the page. This allows developers to use custom tags in their JSP pages to encapsulate reusable functionality.
The Anatomy of a JSP page?
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.
What is the difference between JSTL and JSP?
The Difference between JSTL and JSP is that, JSP lets the person add embedded Java code into HTML pages. Also JSP allows the person to define their own tags. JSTL is just a standard tag library provided by Sun to carry out common tasks.
What is the difference between HTML and JSP?
HTML is client side. JSP is server side.HTML provides a means to describe the structure of text-based information in a document - by denoting certain text as links, headings, paragraphs, lists, and so on - and to supplement that text with interactive forms, embedded images, and other objects. HTML is written in the form of tags, surrounded by angle brackets. HTML can also describe, to some degree, the appearance and semantics of a document, and can include embedded scripting language code (such as JavaScript) which can affect the behavior of Web browsers and other HTML processors.The JSP syntax adds additional XML-like tags, called JSP actions, to be used to invoke built-in functionality. Additionally, the technology allows for the creation of JSP tag libraries that act as extensions to the standard HTML or XML tags. Tag libraries provide a platform independent way of extending the capabilities of a Web server. JSP is alot like php.
What is the anatomy of a jsp page?
A JSP (JavaServer Pages) page consists of HTML for structure, JSP scriptlets (<% %>), JSP expressions (<%= %>), and JSP directives (<%@ %>). Scriptlets contain Java code that can be executed, expressions are used to display output, and directives provide instructions to the JSP container. JSP pages are processed by the server to generate dynamic content for client display.
What are the advantages and disadvantages of JSP?
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.
How do you explain What is a Scriptlet?
In JavaServer Pages (JSP) technology, a scriptlet is a piece of Java-code embedded in the HTML-like JSP code. The scriptlet is everything inside the <% %> tags. Between these the user can add any valid Scriplet i.e. any valid Java Code. Scriptlets are executed at request time, when the JSP engine processes the client request. If the scriptlet produces output, the output is stored in the out object, from which you can display it.
How do you dynamically identify the jsp in servlet?
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.
