A) DirectiveB) ExpressionC) scriptletD) Declaration Any text, HTML tag, or JSP element you write must be outside the scriptlet. Here is the first simple example of JSP – 8. Specify whether the following statements for the declaration element are True or False.i) The declaration elements are indeed global.ii) The declaration element syntax begins with the open standard JSP tag, followed by a colon (<%:). A) i-True, ii-FalseB) i-True, ii-TrueC) i-False, ii-TrueD) i-False, ii-False Ans: The main difference between ServletContect and PageContext is that the ServletContext provides information about the container, and on the other hand, the PageContext provides information about the request. 3. Specify whether the following servlet statements are True or False.i) Once a servlet is started, it remains in memory and can handle multiple HTTP requests.ii) Servlets do not run on the client, all execution takes place on the server.iii) A servlet is limited by support for the HTML specification. A) i-True, ii-False, iii-TrueB) i-True, ii-True, iii-FalseC) i-False, ii-True, iii-TrueD) i-True, ii-True, iii-True A scriptlet can contain an unlimited number of JAVA statements, variable declarations, or valid methods or expressions in the page scripting language. 13.
Specify whether the following statements for implicit objects are True or False.i) The response object processes the flow to the client.ii) The response object is typically used by JSP page authors.iii) The exception object can only be accessed from a single error page. A) i-True, ii-False, iii-TrueB) i-True, ii-True, iii-FalseC) i-False, ii-True, iii-TrueD) i-True, ii-True, iii-True Note that a semicolon is not allowed in a JSP expression, even if the same expression contains a semicolon when you use it in a scriptlet. 23. The page directive is used to pass information about the page to the JSP container. Which of them are the legal syntax of the page directive. Select the two correct statements: The isScriptingEnabled attribute determines whether script elements can be used or not. The default value is true and enables scriptlets, expressions, and declarations. If the attribute value is set to false, a translation time error is generated if the JSP uses scriptlets, expressions/declarations.
In the web service version of the hello1 application, response.jsp contains the following scriptlet that gets the proxy that implements the service endpoint interface. It then calls the sayHello method on the proxy and passes the user name retrieved from a query parameter: 11. is used to track information about a specific client while using a stateless connection protocol such as HTTP. A) config objectB) pageContext objectC) session objectD) application object Ans: Methods can be declared for use in a JSP page. Methods are called in all other methods that you declare, or in scriptlets and JSP expressions. 24. Is the following JSP code legal? Select the correct statement. Hello, I have often thought about this interview JSP Questions and answers Nice that it is presented so clearly. Great revelation. I have an external object and want to click a custom field instead of the default Salesforce name field on the record. I found many alternatives, such as creating a formula field and making it clickable. The problem here, however, is that external objects lack the flexibility to create formula fields.
But great job man, keep up to date with new updates. Thank you, Preethi Read extensively about each of them on JSP Implicit Objects.19. ### Can implicit JSP objects be used in a method defined in the JSP declaration? 20. Specify whether the following statements for JSP scriptlets are True or False.i) Java code in scriptlets is executed when the user requests the page.ii) The JSP scriptlet is used to execute server-side logic. a) i-True, ii-False B) i-True, ii-TrueC) i-False, ii-TrueD) i-False, ii-False 7. The purpose of an element .. is to initialize variables and methods and make them available for other declarations, scriptlets, and expressions. A) DirectiveB) StatementC) scriptletD) Expression JSP interview questions are very important if you decide to do a Java interview. JSP is an integral part of every Java EE web application and lately I`ve been writing a lot about various JSP functions. We started with JSP basics, JSP scripts, and ended with custom JSP tags to avoid Java code in JSP pages.
Some of the tutorials you can watch are: Q33. What are the steps for reading form data using JSP? There is only one syntax for the Action element because it conforms to the XML standard – TLD stands for Tag Library Descriptor file. It contains information about the tag and tag handler classes. It must be stored in the WEB INF directory. ANS: Custom tags in JSP are created by doing the following. A script expression is then used to insert the resp value into the output stream: Defines page-dependent attributes, such as scripting language, error page, and buffer requirements. ANS: RequestDispatcher() and context.getRequestDispatcher() are used for the following purposes. Q49. When does a container initialize multiple JSP objects? 26. A JSP page uses the java.util.ArrayList class multiple times. Instead of referencing the class by its full package name every time, we just want to use ArrayList. Which attribute of the page directive must be specified to achieve this.
Select the correct answer. _jspService(): The container calls the _jspService() method for each query and passes it to the objects. ANS: You can override the jspInit() and jspDestroy() methods in a JSP page. It is a good programming practice to share all allocated resources in jspDestroy(). The jspInit() and jspDestroy() methods are executed only once during the lifecycle of a JSP page and are typically declared as JSP declarations: The etiology of RA is unknown Established family genetic predisposition Studied A similar type of data validation is performed on the server side after the form is submitted. If validation fails, the additional network trip is required to return the form to the customer to repopulate the form with the correct data. A JSP expression is used to insert the value of a string-converted scripting language expression into the stream returned to the client. If the scripting language is the Java programming language, an expression is converted to a statement that converts the value of the expression to a String object and inserts it into the implicitly out object. We would explain the JSP directive in a separate chapter JSP Directives NOTE – Suppose Apache Tomcat is installed in C:apache-tomcat-7.0.2 and your environment is configured according to the environment setup tutorial. computer-associates-placement-paper-February-14-2012-3163.doc Years: Yes, the caching process can be disabled on the browser`s Back button. To do this, we can use the following code below. 16.
The . object is an instantiation of a java.lang.Throwable object. A) ApplicationB) PageC) SessionD) Exception Q19. How can we stop errors when viewing on a JSP page? Which statement, if placed at position XXX, can be used to calculate the sum. Select the correct statement. ANS: Object cloning is a process of creating an exact copy of the existing object. The clone() method of the Object class is used to clone an existing object. The class whose object is attempting to clone the object is supposed to implement the java.lang.Cloneable interface. If the Cloneable interface is not implemented, the clone() method throws the CloneNotSupported exception.
Very very helpful answers to questions, I read almost all the journaldev topics, thank you, I really enjoyed a great job. stackoverflow.com/users/1249325/khan 5. the elements used in JSP allow Java code to be embedded directly into the JSP page. A) DirectiveB) DeclarationC) ScriptletD) Action to: JSP is preferable for creating a web-based client program. Because no security policy plug-ins/files are required on client systems, Applet does. In addition, JSP pages enable cleaner and more modular application design because they allow application programming to be separated from web page design. This means that employees involved in web design don`t need to understand the syntax of the Java programming language to do their jobs. ANS: There are two ways to skip the execution of an expression language (EL) on a JSP page. Used to write template text in pages and JSP documents.
