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 does jsp mean?
jsp means Java Server Pages.
What are the Implicit object in JSP?
The implicit objects in a JSP page are:requestresponsepageContextsessionapplicationoutconfigpage
Difference between JSP and CGI programming?
JSP stands for JAVA SERVER PAGES, where as CGI stands for COMMON GATEWAY INTERFACE. In CGI, whenever a multiple requests of the same dynamic web page is made by the client to the server, a new process is cerated of the corrosponding CGI program, for each an every request generated as such.. this is not the case in JSP.. in JSP, when the first request is made for a dynamic web page..its corrosponding class file an hence the servlet is then cached in the memorey, and hence new threads are generated for the futher requests made, saving resources..
What are the JSP lifecycle methods?
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
How is PERL different from HTML?
Perl is a server-side language. It is executed on the server, and any output generated is sent to the client (the user).HTML is read and executed by the client. It is simply sent, as is, by the server.

What is client program?
As far as web programming is concerned, client side programming is code that runs in the web browser, rather than the web server. JavaScript is an example of client side scripting because the code is sent to the browser, at which point it is executed. PHP is an example of server side scripting because the code is executed on the server, and the resulting code is sent to the browser and displayed.
Difference between JSP and JAVA Script?
Hi, 1. JSP is a server side scripting while Javascript is as client side scripting language. 2. JSP also connects with database to fetch up the records from the database while javascript can be used for validate the code on client side.
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.
Why must the server program be executed before the client program?
A server program must be executed before the client program because once a client is run, it will attempt to initiate a connection with the server. If the server is down, then the client will not be able to make a connection.
Difference between java script and java server page?
JavaScript and JavaServer Pages (JSP) serve different purposes and operate in different environments within web development. Here are the key differences between them: Language Type and Purpose: JavaScript: JavaScript is a client-side scripting language. It is used primarily to make web pages interactive and to create dynamic content that runs in the user's web browser. It is embedded directly into HTML and is executed on the client's side. JSP (JavaServer Pages): JSP is a server-side technology. It is used to create dynamically generated web pages based on HTML, XML, or other document types. JSP allows embedding Java code into HTML pages and is executed on the server side before the page is sent to the client's browser. Execution Environment: JavaScript: Runs in the browser on the client side. It interacts with the Document Object Model (DOM) of the web page and can be used to handle events, validate forms, and update the content of a web page without requiring a full page reload. JSP: Runs on the server. When a web page request is made, the JSP engine on the server processes the embedded Java code and produces an HTML page (or other document types) to send back to the client's browser. Syntax and Integration: JavaScript: Uses a syntax based on the ECMAScript standard. It is often used in conjunction with HTML and CSS to create interactive web pages. JavaScript code is included directly within HTML files using the tag or in separate .js files. JSP: Uses Java code within HTML tags, utilizing JSP-specific tags and expressions. It allows for the inclusion of JavaBeans, custom tags, and servlets. JSP files typically have a .jsp extension. Use Cases: JavaScript: Ideal for tasks that require immediate interaction with the user, such as form validation, animations, handling user inputs, and making asynchronous requests (AJAX) to update content without refreshing the page. JSP: Suitable for generating dynamic web content on the server side, such as fetching data from a database, performing business logic, and preparing content before it is sent to the client. It is often used in conjunction with Java Servlets and frameworks like JavaServer Faces (JSF) or Spring MVC. Dependency: JavaScript: Does not depend on a specific server technology. It runs in the browser and can work with any server-side technology or static HTML files. JSP: Requires a Java-enabled server, such as Apache Tomcat, Jetty, or IBM WebSphere, to compile and execute the JSP code on the server side. In summary, JavaScript and JSP are fundamentally different technologies designed for different aspects of web development. JavaScript enhances the interactivity and user experience on the client side, while JSP handles the generation of dynamic content on the server side before delivering it to the client's browser.
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 is the difference between requestgetattribute and requestgetParameter in JSP?
request.getAttribute() is used on the Server side Java code to get values submitted from the form onto the Servlet or other java classes request.getParameter() is used on the JSP page to get values sent by the servlet and display it in the jsp page

Is JSP server side language?
Yes... Java server page is server side language . but it can create client side code in format of HTML . When the request send the web server the jsp process the HTML request and HTML response. by Arulmurugan C
Which one is faster servlet OR jsp?
Servlet is more faster than JSP, but JSP is more convenient than Servlet and JSP is clearly superior, shorter, simple and easier to use. JSP can be perceived as Java in HTML code. JSP require no explicit compilation as like servlets and can keep in the web application server as HTML file. The web application server in turn compile the java code in JSP and load it in its library for future execution. Servlet can be perceived as HTML in Java code. The servlet is the class file, which would be loaded in the web application server as a program. The program output will be directed to the outstream object which in turn direct to the client as HTML elements.
